Understanding United Airlines fare class system can transform your booking strategy and significantly improve your travel experience. Here are the essential insights every traveler should know:
- Fare classes determine upgrade eligibility: Y and B class tickets offer the best upgrade chances, while Basic Economy (N class) blocks all upgrade opportunities entirely.
- Expert Mode reveals hidden inventory: Activate this feature in your MileagePlus settings to view all available fare buckets and make strategic booking decisions.
- Higher fare classes accelerate elite status: Full-fare tickets earn more Premier Qualifying Points, helping you reach elite status faster than discounted fares.
- Award availability favors MileagePlus members: Premium cabin awards use “IN” fare codes exclusively for United elites and cardholders, blocking partner program access.
- Basic Economy restrictions extend beyond price: N-class tickets don’t earn Premier Qualifying Flights and come with baggage, seat selection, and change limitations.
The key to booking like an expert lies in balancing price with benefits. Sometimes paying slightly more for a higher fare class delivers significantly better value through upgrade opportunities, flexibility, and accelerated elite status progress.

Most regular travelers don’t realize that a fare basis code’s first letter could determine their upgrade eligibility – a surprising 60% are unaware of this fact. Understanding United fare classes might make the difference between securing that coveted upgrade or staying put.
United Airlines has raised Premier status thresholds by approximately 25%, based on recent data, making elite status more challenging to achieve. But smart travelers who understand fare classes can maximize their status earnings effectively.
The numbers tell an interesting story. A concerning 35% of Basic Economy passengers later wished they hadn’t booked that fare after facing luggage restrictions and seat assignment problems. Y-class fare bookings show much better results, with travelers reporting a 50% higher upgrade success rate compared to budget options.
The lower price point of Basic Economy tickets might catch your eye, but these fares bring stricter limitations. To cite an instance, passengers earn zero Premier Qualifying Flights (PQF), which they need to achieve elite status.
The next sections will explain United fare classes, their impact on your travel experience, and expert booking strategies. Let’s explore these insights together!
What Are United Fare Classes and Why They Matter
United fare classes use letter codes to categorize tickets based on their features and pricing. These codes may look confusing, but they can affect your travel experience in many ways.
Understanding fare buckets and codes
United Airlines uses fare buckets (also called fare classes) as inventory management tools to track ticket sales and seat availability for each flight. Prices usually increase to the next available fare class once a particular fare bucket sells out.
These fare classes determine several vital aspects of your ticket:
- Mileage and Premier Qualifying Point (PQP) earnings
- Upgrade eligibility and PlusPoints requirements
- Change and refund flexibility
- Overall travel experience
Knowing these codes gives you an advantage during booking. You can improve your chances of getting an upgrade by understanding which fare classes allow upgrades.
How many fare classes does United Airlines have?
United Airlines uses many fare classes in its different cabins. Each letter code stands for a specific ticket type with unique benefits and rules.
First and Business Class fare codes:
- J: Full fare
- C, D: High fare
- Z: Discounted fare
- P: Deepest-discounted fare
Premium Plus fare codes:
- O: High fare
- A: Discounted fare
- R: Deepest-discounted fare
Economy fare codes:
- Y, B: Full fare – eligible for regional instant upgrades
- M, E, U, H: High fare
- Q, V, W: Discounted fare
- S, T, L, K: Deep-discounted fare
- G: Deepest-discounted fare
- N: Basic economy (domestic and short-haul international)
What does United fare class mean?
The fare class on your United Airlines ticket shows more than just your cabin. It reveals which specific “bucket” of tickets you bought within that cabin.
Your fare class affects:
- Status earning potential – Higher fare classes help you reach elite status faster by earning more Premier Qualifying Points (PQP) based on ticket price. Basic economy tickets (N class) earn PQP but don’t count toward Premier Qualifying Flights (PQF).
- Upgrade opportunities – Elite members can get instant upgrades with full-fare economy tickets (Y and B classes) under certain conditions. Discounted economy fares need more PlusPoints or might have limited upgrade spots.
- Mileage accrual – Partner programs like Air Canada Aeroplan base mileage earnings on your fare class instead of ticket price.
- Flexibility – Better change and cancelation terms come with higher fare classes, though United offers refundable options in various fare classes.
Price differences are most obvious within the same cabin. Domestic flights may let you upgrade from a discounted fare to a fully refundable one. Long-haul international flights usually offer three pricing tiers for the lowest economy fare class: basic economy, standard economy, and flexible economy.
You can see available fare classes by turning on “Expert Mode” in your United MileagePlus profile settings. This feature helps you make smarter booking decisions by showing all fare class inventory during your search.

Each letter in United’s fare codes tells you exactly what kind of ticket you’re getting – complete with its own perks and limits. Learning these differences helps you book smarter and get the most from your travel.
Economy: Y, B, M, H, Q, V, W, S, T, L, K, G, N
Economy class has the biggest selection of fare codes, with prices and flexibility that match every budget:
- Y, B: These are full-fare economy tickets that give you total flexibility and the best rewards. All elite members can grab instant upgrades on regional flights if upgrade seats are open.
- M, E, H, U: You’ll get good flexibility with these high-fare economy tickets. Premier 1K members can snag instant regional upgrades with M-class tickets.
- Q, V, W: These economy fares come with some limits but cost less. W-class stands out because it’s the lowest fare that lets you upgrade to Polaris.
- S, T, L, K: You’ll save more money with these economy fares, though they come with more restrictions.
- G: This is the lowest-priced regular economy fare you can buy.
- N: Basic economy works for domestic and short international flights. The prices are rock-bottom, but you’ll face limits on bags, seats, and changes.
Premium Plus: O, A, R
United’s premium economy product, Premium Plus, comes in three flavors:
- O: You get maximum flexibility and rewards with this high-fare Premium Plus
- A: This discounted Premium Plus gives you good value while keeping some flexibility
- R: The lowest-priced Premium Plus option saves you money but has more restrictions
Premium Plus hits the sweet spot between economy and business. It’s perfect for longer flights where you want extra comfort without splurging on business class.
Business and First: J, C, D, Z, P
The premium cabin options deliver United’s best service levels:
- J: Full-fare business/first class lets you change plans freely and earn maximum rewards
- C, D: High-fare business/first class tickets
- Z: A business/first class fare that costs less but still offers great value
- P: The most affordable business/first class option still gives you a premium experience
These premium fares include priority everything, better food choices, and lie-flat seats on planes that have them.
United Airlines fare classes for domestic vs international flights
The fare classes work differently on domestic and international flights:
- Basic Economy (N) shows up mostly on domestic and shorter international routes
- Long-haul international flights usually come with three price levels in each fare class:
- Basic economy gives you fewer perks
- Standard economy includes normal perks
- Flexible economy adds full refunds to standard perks
Domestic flights have fewer fare options in each cabin compared to international routes.
United Airlines fare class comparison table
| Fare Class | Cabin | Flexibility | Upgrade Eligibility | Mileage Earning |
|---|---|---|---|---|
| J | First/Business | Highest | N/A (already premium) | Highest (150-200%) |
| C, D | First/Business | High | N/A (already premium) | High (150%) |
| Z, P | First/Business | Moderate-Low | N/A (already premium) | Good (125-150%) |

| S, T, L, K | Economy | Low | Limited availability | Lower (50%) |
| G | Economy | Very Low | Very limited | Lowest (25-50%) |
| N | Basic Economy | None | Not eligible | Limited (25-50%) |
The right fare class depends on what you need. Look beyond the price tag – upgrade chances, miles earned, and flexibility might be worth the extra cost, especially on longer flights.
Upgrade Fare Classes and PlusPoints Rules
Your ticket’s fare class determines your access to premium cabin experiences through United’s upgrade system. A clear understanding of upgrade eligibility helps you book flights that maximize your chances of getting a better seat.
What United fare classes are upgradeable?
All but one of these United fare classes are upgradeable – basic economy (N). Notwithstanding that, upgrades have different tiers:
- Regular economy fares (Y through G) can be upgraded to Premium Plus or Polaris
- Premium Plus fares (O, A, R) can be upgraded to Polaris business
- Deeply discounted economy fares (S, T, L, K, G) require more PlusPoints
Your chances of clearing the upgrade waitlist improve with higher fare classes within each cabin.
PN, PZ, RN: What they mean
These special codes represent United’s upgrade inventory buckets:
- PN: Reserved for Global Services members and instant upgrades for Premier 1K customers on eligible full-fare economy tickets
- PZ: Available for Premier Platinum and 1K members using PlusPoints or mileage awards; also used for Complimentary Premier Upgrades
- RN: Upgrade inventory for Premium Plus seats for all members
How PlusPoints work by fare class
United awards PlusPoints as upgrade currency to Premier Platinum (40 points) and Premier 1K members (320 points). Your original ticket determines the cost:
| Upgrade Type | Standard Economy | Discounted Economy | Premium Plus |
|---|---|---|---|
| To Premium Plus | 20 PlusPoints | 20 PlusPoints | N/A |
| To Polaris (long-haul) | 40 PlusPoints | 80 PlusPoints | 30 PlusPoints |
PlusPoints are deducted only after upgrades clear, except for partner airline upgrades.
Can I upgrade United fare class?
Several methods are available:
- Complimentary Premier Upgrades (for elite members)
- PlusPoints (for Platinum and 1K members)
- MileagePlus miles + possible co-pay
- Cash upgrades at check-in or at the gate
Each method comes with specific fare class requirements, costs, and clearance timelines.
Which fare class gives instant upgrades?
Elite members traveling on Y and B fare classes (plus M for Premier 1K) could receive instant upgrades when upgrade space was available. United has announced the elimination of instant upgrades for Y, B, and M fares starting August 21, 2025. Premier 1K members can still use the “Skip Waitlist” feature with PlusPoints on flights more than 30 days away.
Award Fare Classes and Mileage Redemption
MileagePlus miles give you access to a different set of fare classes for award travel, beyond just paying cash. These codes tell you about seat availability, pricing, and if you can book those seats with your miles.
Saver vs Everyday awards: I, IN, JN, X, XN, YN
Award tickets come in two main types:
- Saver Awards: These give you the best value but are harder to find. You’ll need fewer miles, making them the best way to use your points.
- Everyday Awards: These are easier to find but cost way more miles. The prices change based on demand, cash price, and other factors.
Award fare codes help you learn about seat availability:
| Fare Code | Cabin | Who Can Access | Availability |
|---|---|---|---|
| I | Business/First | All members & partners | Very limited |
| IN | Business/First | Elite members, cardholders | Much better than I |
| JN | Business/First | Everyday awards (all members) | Dynamic pricing |
| X | Economy | All members & partners | Limited |
| XN | Economy | Elite members, cardholders | “Fare Code” |
| YN | Economy | Everyday awards (all members) | Dynamic pricing [193] |
United Polaris fare class for award tickets
United has made a big change by limiting Polaris business class awards to MileagePlus members. Most premium seats now show up in the “IN” fare bucket instead of “I”.
Only these travelers can book Polaris award seats:
- MileagePlus Premier members (all tiers)
- Holders of co-branded MileagePlus credit cards with annual fees
How award fare classes affect partner redemptions
Partner airlines can only book seats in specific fare buckets:
- “I” for business/first class (not “IN”)
- “X” for economy (not “XN”)
United’s choice to use “IN” instead of “I” for Polaris awards blocks partner programs from accessing these seats.
Partner award rates have dropped:
- Business class to Europe: Down from 88,000 to 80,000 miles
- Transpacific business class: Down from 110,000 to 100,000 miles
United Airlines ticket types for award travel
United uses dynamic pricing without an official award chart, but you’ll notice some patterns:
- Short-haul flights: Start at just 5,000-6,000 miles
- US to Europe economy: Around 40,000 miles (saver level)
- US to Europe business: About 80,000 miles (saver level)
Booking United-operated flights with miles usually costs less than partner flights. This makes United’s own flights a better value when using your miles.

How does activating Expert Mode help when booking United flights?
Expert Mode, activated in your MileagePlus account settings, allows you to view detailed fare bucket availability when searching for flights. This visibility helps you make strategic decisions about which fare class best suits your travel needs and upgrade prospects.
What is a fare class on United Airlines?
A fare class is a letter code that determines your ticket’s price, benefits, and flexibility. It’s essentially the specific type of ticket you’ve purchased within your cabin class, affecting everything from seat selection to upgrade eligibility.
How many fare classes does United Airlines have, and how are they organized?
United operates with dozens of fare classes organized into four main cabin categories: First/Business (J, C, D, Z, P), Premium Economy (W, S, E), Economy (Y, B, M, H, Q, K), and Basic Economy (restricted codes). Each letter represents different price points and perks within its cabin.
How do United fare classes differ between first/business, premium economy and economy?
Higher fare classes in first/business offer full flexibility, lounge access, and premium earning rates, while premium economy provides extra space with moderate benefits. Standard economy fare classes balance price and perks, whereas basic economy strips away most flexibility for the lowest fares.
Where can I find the fare class for my United flight when booking?
Your fare class appears as a single letter on your ticket receipt and confirmation email. You can also spot it in your MileagePlus account under trip details or by checking the fare rules during the booking process on United’s website.
Why should I pay attention to the fare class I book with United?
Fare class determines your upgrade eligibility, mileage earnings, change fees, and seat selection options. Booking the right fare class can mean the difference between a rigid, restrictive ticket and one that adapts to your travel needs.
How does fare class affect elite status qualification with United?
Your fare class directly impacts how many Premier Qualifying Points (PQPs) and Premier Qualifying Flights (PQFs) you earn. Premium fare classes like Y or B earn 100% of flight miles, while deeply discounted classes might earn significantly less toward your status goals.
Are certain fare classes eligible for complimentary upgrades on United flights?
Full-fare economy tickets (Y, B fare classes) and premium cabin fares have priority for complimentary upgrades if you hold elite status. Basic economy and heavily restricted fare classes typically aren’t eligible for any complimentary upgrade considerations.
Can fare class affect how many miles or points I earn with United or partner programs?
Absolutely—higher fare classes earn more redeemable miles and elite-qualifying credits. A first-class J fare might earn 150-300% of flight distance, while a basic economy ticket could earn just 25% with United and even less with partner airlines.
What’s the difference between basic economy and other economy fare classes on United?
Basic economy restricts seat selection, doesn’t allow changes or cancellations, boards last, and earns fewer miles. Standard economy fare classes (K, L, Q, M) offer more flexibility, better earning rates, and the ability to select seats and make changes for a fee.
Is there a way to book a specific fare class on United’s website?
United’s website typically shows fare options by price and category rather than specific letter codes. To target a particular fare class, work with a travel agent or call 888-635-5228 directly—they can search inventory by specific fare class codes for your route.
