US airline upgrade types compared: miles and status

US airline upgrade types compared is a guide to the four upgrade routes US carriers use — complimentary, certificate, points-based and paid — and to the published rules behind them. On the points side, United MileagePlus members can use miles to upgrade a ticket with Star Alliance Upgrade Awards on partner-operated flights such as Turkish Airlines, SWISS, South African Airways and Singapore Airlines.

Key takeaways

  • There are four upgrade routes to compare — complimentary, certificate, points-based and paid — and each one has its own entry in the encyclopedia.
  • MileagePlus members can use miles to upgrade a ticket with Star Alliance Upgrade Awards on Turkish Airlines, SWISS, South African Airways and Singapore Airlines flights. [7] [8] [9] [10]
  • Service charges may apply to those upgrade awards, and the charge depends on the type of ticket, the travel dates and the member's MileagePlus status. [7] [8] [9] [10]
  • Award tickets cannot be issued at the airport, so an upgrade that needs an award ticket has to be handled before the airport. [7] [8]

What are the four main upgrade types?

The four labels describe what a traveller exchanges to move cabins: nothing beyond the ticket itself, a certificate, miles or points, or cash. The table below points to the entry that explains each route in full.

The points-based route is the one United sets out most fully on its partner pages through Star Alliance Upgrade Awards, which a MileagePlus member can apply to a partner-operated ticket. [7] [8] [9] [10] On those carriers, Premier members also receive Star Alliance Gold or Silver benefits while travelling. [7] [8] [9] [10]

How do MileagePlus miles pay for an upgrade?

The mechanism is the Star Alliance Upgrade Award. United's pages for Turkish Airlines, SWISS, South African Airways and Singapore Airlines all state that MileagePlus members can use miles to upgrade a ticket with Star Alliance Upgrade Awards, alongside the option of booking a regular award flight online or through the reservations line. [7] [8] [9] [10]

Price is not a single flat figure. Each of those pages says there may be service charges, and that the charge depends on the type of ticket, the travel dates and the member's MileagePlus status. [7] [8] [9] [10] The same pages state that award tickets cannot be issued at the airport, which applies to the award side of the booking rather than to the upgrade request itself. [7] [8]

How do members earn the miles they spend?

Points-based upgrades are funded from the member's MileagePlus balance, so the earn rate matters. For tickets bought directly from United and issued on or after April 2, 2026, award miles are calculated on the fare price together with MileagePlus status and, where it applies, United card membership. [7] [8] [9] [10]

General member3 miles per dollar6 miles per dollar
Premier Silver5 miles per dollar8 miles per dollar
Premier Gold6 miles per dollar9 miles per dollar
Premier Platinum7 miles per dollar10 miles per dollar
Premier 1K9 miles per dollar12 miles per dollar

The United MileagePlus Debit Rewards Card and United Gateway Card unlock the Cardmember earn rates after $10,000 of spending on the card within a calendar year. [7]

Tickets bought from another airline, a third-party website or a travel agency earn on flight distance and fare class instead. [7] On Turkish Airlines-operated flights, business classes C, D, Z and K earn 125% of miles flown, discount business J earns 100%, deep discount economy T, L and V earn 50%, and fare classes F, G, I, N, P, R, U, W and X earn no miles at all. [7]

What limits apply to these rules?

  • Fare class follows the operating carrier. Award miles accrued on codeshare flights are based on the operating carrier and its equivalent fare class, which can differ from the booking class purchased. [7] [8] [9] [10]
  • Some operators are excluded. On the Turkish Airlines page, flights operated by AJet are not eligible for mileage accrual or redemption. [7]
  • Upgrade cost is not fixed. The service charge attached to a miles upgrade depends on ticket type, travel dates and status, so the same cabin can cost different amounts on different bookings. [7] [8]
  • Award tickets are not airport-issued. The partner pages state that award tickets cannot be issued at the airport. [7] [10]
  • Published rules set eligibility and price, not a seat. Whether an upgrade actually clears on the day depends on fare class, route, status and operational availability.
