Terms and conditions

1. The united.com Low Fare Guarantee applies to customers who make a qualifying airfare purchase on flights operated by United Airlines or United Express and sold under the UA code, and do so through the united.com website on or after February 7, 2005. The offer is not valid for itineraries that include flights marketed or operated by other airlines (including United-marketed codeshare/Star Alliance-operated flights and Star Alliance-marketed codeshare/United or United Express operated flights).
   
2. Your claim must be made by midnight Central Time of the same day on which the ticket is purchased. Claims must be made by filling out an online claim form on united.com. The claim must satisfy all terms and conditions and must be submitted in compliance with the claims processing procedures, all as set out herein. Claims for the Low Fare Guarantee may only be made through the online claim form. No other claims will be accepted.
   
3. Tickets must be the least expensive available on united.com for the chosen itinerary at the time of purchase. The guarantee is valid only for published retail fares available on the Internet for the exact same flight(s), travel date(s), and travel itinerary for the same number of passenger(s). Fares must be in the exact same cabin(s) (First, Business, Economy) and carry the exact same fare rules and restrictions. Tickets must be purchased with a credit card and valid United States billing address and travel must originate in the 50 United States.
   
4. United Airlines must be able to verify the lower online fare online at the time of claim. The confirmed airfare purchased on united.com will be compared to the available airfare on the screen just prior to purchase confirmation of the other website, which must be an accredited distributor of United airfare. Please keep a copy of methods of verification (e.g. screen prints) in case additional verification is necessary.
   
5. The Low Fare Guarantee does not apply to unpublished fares that are not available to the general public and fares that cannot be purchased on united.com. Fares not available to the general public include, but are not limited to, corporate, military, government, wholesaler, consolidator, opaque agencies and other discount fares. The Low Fare Guarantee does not apply to package fares, such as airfares sold as part of a travel package, nor does it apply to airfares on another website that have been reduced as a result of promotional discounts, such as dollars off coupons, loyalty program discounts or fly free offers. The Low Fare Guarantee does not apply to tickets that you choose to refund.
   
6. Guarantee does not apply to fare differences of less than $10. For qualifying fare differences, United will issue the passenger(s) an electronic certificate, totaling $100 plus the difference in fare (rounded up to the nearest $5 increment). The electronic certificate is redeemable only for a future purchase of a ticket for travel on United Airlines or United Express flights sold under the UA code. The certificate is not valid for itineraries that include flights marketed or operated by other airlines (including United-marketed codeshare/Star Alliance-operated flights and Star Alliance-marketed codeshare/United or United Express operated flights). The electronic certificate is only valid for use through united.com and is valid one year from date of issue. The electronic certificate may only be applied to travel within the 50 United States, Canada, Puerto Rico and the U.S. Virgin Islands. All terms and conditions listed on the electronic certificate apply to usage. Electronic certificates will not be replaced for any reason.
   
7. The electronic certificate for the difference in fare plus an additional $100 is the sole and exclusive compensation that will be provided for United's failure to fulfill its Low Fare Guarantee.
   
8. United is the final authority on the interpretation of these rules. United Airlines reserves the right to terminate this offer at any time without notice.
