Question 1

What are airline upgrade certificates?

Accepted Answer

Upgrade certificates are perks offered by major airlines to elite frequent flyers, allowing them to move from a lower cabin class (e.g., economy) to a higher one (e.g., business or first class) on paid tickets. The availability, rules, and best uses vary by airline.

Question 2

Which airlines offer upgrade certificates?

Accepted Answer

American Airlines, Delta Air Lines, and United Airlines all offer upgrade certificates through their loyalty programs for upper-tier elite members. Each program has its own name: Systemwide Upgrades (American), Global and Regional Upgrade Certificates (Delta), and PlusPoints (United).

Question 3

Can I use upgrade certificates on award tickets?

Accepted Answer

No. All three major U.S. airlines — American, Delta, and United — require you to purchase a paid, eligible fare to apply upgrade certificates. They are not valid on award tickets booked using miles.

Question 4

Can I confirm my upgrade at the time of booking?

Accepted Answer

Sometimes. If upgrade space is available, you can confirm your upgrade immediately. Otherwise, your upgrade request will be placed on a waitlist. United and American allow instant confirmation more often than Delta.

Question 5

Which upgrade program is the most flexible?

Accepted Answer

United’s PlusPoints system is the most flexible, letting members choose how to spend their upgrade points across various routes and classes. You can use them for short domestic upgrades or long-haul international Polaris upgrades.

Question 6

Which upgrade certificates are best for international travel?

Accepted Answer

American Airlines Systemwide Upgrades (SWUs) and Delta’s Global Upgrade Certificates (GUCs) are both strong options for international travel. SWUs are more widely usable, including on British Airways, while GUCs work only on Delta flights.

Question 7

Do upgrade certificates expire?

Accepted Answer

Yes. Upgrade certificates usually expire one year after they are issued, although this may vary based on your elite status cycle and the airline's policy. Always check expiration dates when planning travel.

Question 8

Can I use upgrade certificates on basic economy fares?

Accepted Answer

Only American Airlines allows you to use upgrade certificates on basic economy fares. Delta and United require you to book in higher fare classes to qualify for upgrades using certificates.

Question 9

Can I transfer my upgrade certificates to someone else?

Accepted Answer

Generally, yes. All three airlines allow you to apply upgrade certificates to tickets booked for other travelers, as long as the booking is made under your loyalty account or you're able to assist in managing the reservation.

Question 10

Are upgrades guaranteed with certificates?

Accepted Answer

No. Upgrade certificates are only confirmed if space is available. If not, your request will go on a waitlist, and upgrades may clear closer to departure based on elite status and availability.
