Terms and conditions

Travel certificates expire one year from original date of issue, unless otherwise noted. They are redeemable toward transportation on any flight operated by United Airlines or United Express. Otherwise, travel certificates are not valid on flights operated by other airlines, including United marketed codeshare and Star Alliance flights.

You'll enter your travel certificate details on the Payment page of united.com when booking a flight. On that page, select “United payment types” and then “Electronic travel certificate.” The certificate amount will then be applied to the total trip price. If you’d prefer to book your reservation over the phone, call 1-800-UNITED-1 (1-800-864-8331). A fee may apply for redemption by phone. You’ll be asked to provide the last name of the certificate recipient. Certificates may not be redeemed through a travel agency.

The promotion code and PIN must be presented at time of ticket purchase.

Travel Certificates have no cash value.

Travel Certificates will not be honored in conjunction with prepaid tickets, fee-waived tickets, MileagePlus awards, tour packages or other service charges, including excess baggage charges, pet charges, etc.

If the face amount of the Travel Certificate exceeds the cost of the ticket for which it is surrendered, any residual amount will be applied to the same PIN for use toward another ticket until either the original issued amount is depleted or the expiration date has been reached, whichever comes first.

Travel Certificates are not transferable and may not be sold, traded or bartered. However, the original recipient of this Certificate may arrange travel for another person if done without selling or bartering this Certificate. Any sale or barter of Certificates, or any offer to sell or enter into such a transaction, shall render Certificates null and void such that Certificates shall no longer be redeemable by any person, including the original recipient.

Positive identification may be required when using travel certificates toward the purchase of a ticket. United is not liable for loss, theft or unintended use of travel certificates by a person other than the original recipient.

United's Contract of Carriage applies to all travel on United Airlines and United Express.
