United Airlines Promo Codes & Discount Codes

1. Lock a fare, then use the 24-hour window to keep shopping

   Full refund if you cancel within 24 hoursLow effortAnyone booking directly, 7+ days before departure

   When you book directly with United at least a week before departure, you can cancel within 24 hours for a full refund with no fee — Basic Economy and Money + Miles bookings included. If a lower fare turns up in that time, cancel the whole reservation and rebook; the refund goes back to your original payment, and card refunds are processed within 7 business days. Need longer than a day? FareLock holds the price for 3, 7 or 14 days on select flights, starting at $5.99 for three days, but that fee is nonrefundable and doesn't count toward the ticket.^{[2, 5, 14, 15]}

   1. Book on united.com or the United app at least 7 days before the flight.
   2. Keep comparing fares for the next 24 hours.
   3. If you find better, cancel every flight on the reservation in My Trips and rebook.

2. Choose standard Economy when your plans could change

   No change fee on trips from the U.S.Low effortTravelers whose dates aren't fixed

   Basic Economy can't be changed — the only route is cancelling and buying again — and after 24 hours a cancellation leaves at most a partial travel credit. Standard Economy has no change fee on trips that start in the U.S., and if the new flight is cheaper, the difference comes back as a travel credit. Already on Basic Economy? In My Trips you can add United Economy benefits from $74.50 per traveler per direction domestic ($149.50 international); every passenger on the reservation has to add them, and the charge isn't refundable.^{[1, 2, 14]}

3. Join MileagePlus before you book

   3 miles per dollar and cheaper Wi-FiLow effortEveryone

   MileagePlus is free to join and its miles never expire. On standard fares a general member earns 3 miles per dollar of the fare and carrier surcharges (government taxes don't count), though Basic Economy earns nothing for members without a United card or Premier status. Members pay $8 instead of $10 for per-flight Wi-Fi on U.S. domestic and short international flights without Starlink, and only members can connect on flights with free Starlink Wi-Fi.^{[8, 9, 10, 14, 16]}

   1. Create a free MileagePlus account on united.com.
   2. Add your MileagePlus number to every reservation.
   3. Check it shows on your boarding pass at check-in.

4. Use a United card for free bags and cheaper award flights

   First bag free; at least 10% off awardsHigh effortPrimary United cardmembers

   With the United Explorer Card, the primary cardmember and one companion on the same reservation check their first standard bag free on United-operated flights; the Quest and Club cards cover two bags, and United puts the saving at up to $200 per round trip for one free bag and up to $440 for two. Buy the ticket with the card and keep your MileagePlus number on the booking. Primary cardmembers also book United and United Express award flights for at least 10% fewer miles (at least 15% with Premier status); Gateway and Debit Rewards cardholders unlock that only after spending $10,000 on the card in a calendar year.^{[7, 8, 10]}

5. Active-duty military: verify your status for 5% off

   5% off the base fare, plus free bagsSome effortActive-duty U.S. military

   Active-duty members of the U.S. Army, Navy, Air Force, Marines, Space Force and Coast Guard who verify their status in their MileagePlus profile get 5% off the published base fare on select United-operated flights bought on united.com or the app, for up to nine passengers as long as the service member is on the itinerary. Flights must start in the U.S., Guam, Puerto Rico, the U.S. Virgin Islands or Canada, and Basic Economy, special promotional fares and other discounts are excluded. U.S. military personnel also check bags free on United flights — three bags on personal travel and five on military orders.^{[6, 11]}

Codes and offers kept by David Jones, who lists only codes the store makes public.

United takes promo and offer codes in the promotion section of its flight search, and the fares it then shows already include the discount. We list only codes United publishes itself on united.com; its deals page showed none on October 17, 2026.

1. A Basic Economy bag that won't fit under the seat costs $75 at the gate

   On routes where Basic Economy includes only a personal item, a carry-on brought to the gate that doesn't fit under the seat is checked for $75 on tickets bought on or after April 3, 2026, and there is no free gate check. Premier members, Star Alliance Gold members and primary holders of qualifying United cards (not the Gateway or Select cards) who booked with the card can bring one carry-on.^[1]

2. The 24-hour refund has fine print

   It applies only when you book at least a week before departure, you must cancel every flight for every passenger on the reservation, and tickets bought with e-certificates are excluded. A FareLock fee paid to hold the fare is not refunded.^{[2, 15]}

3. Accepting a rebooked flight ends your refund right

   After a cancellation or major delay, taking the alternative flight United offers means you are no longer entitled to a refund. If you would rather not travel, decline the rebooking and request your money back to the original payment.^[5]

4. The cardmember bag perk depends on how you paid

   Buy the ticket with your United card (new cardmembers get a 90-day grace period) and make sure your MileagePlus number is on the reservation. Codeshare flights and unpublished fares bought through sites such as Priceline or Hotwire don't qualify, and Premier members get no extra bags from the card.^[7]

5. Booking through an agent costs extra

   Booking online is free, but ticketing with a United agent costs $25 by phone within the U.S. and Canada, and changing a flight over the phone can also carry a fee.^{[3, 14]}
