What United Travel Bank is and how it works
United Travel Bank is United Airlines' system for storing travel credits as an account balance you can spend on future flights. When you receive a credit—either from cancelling a ticket, receiving a travel voucher, or through a promotional offer—United deposits it into your Travel Bank instead of issuing a separate certificate or voucher code. You then draw from that balance when you book your next flight.
The key difference from older voucher systems: your credits live in one place tied to your MileagePlus account, not scattered across multiple paper certificates or email codes. You see your balance when you log in, and the system automatically applies credits during checkout if you have them available.
Credits in your Travel Bank do not expire as long as your MileagePlus account remains active. However, the original ticket or promotion that created the credit may have had its own expiration date—once that passes, the credit itself is locked in your Travel Bank and cannot be refunded or transferred, even if unused.
Key Takeaways
- Travel Bank credits appear in your MileagePlus account online and are automatically available when you book a new flight.
- Credits do not expire as long as your MileagePlus account is open, but you cannot get a refund once the original ticket or promotion important date passes.
- You can use Travel Bank credits for any United flight, including basic economy fares, and the system applies them at checkout without requiring a code.
- If you have multiple credits, United applies them in the order they were issued, oldest first, until your balance is used or your fare is covered.
- Travel Bank credits are non-transferable and cannot be converted to cash, miles, or used toward baggage fees or seat upgrades.
How to check your Travel Bank balance
Log into your MileagePlus account on United's website or mobile app. On the main dashboard, look for a section labeled "Travel Bank" or "Account Balance"—the exact placement varies slightly between the website and app, but it appears near your miles balance and account summary.
Click or tap into that section to see your total Travel Bank balance and a list of individual credits. Each credit shows the amount, the date it was issued, and the original expiration date of the ticket or promotion that created it. This list is important: it tells you which credits are still usable and which are locked (meaning the original important date has passed but the credit remains in your account).
If you do not see a Travel Bank section in your account, you may not have any active credits. Credits only appear once they are issued; an empty Travel Bank is normal if you have never received a voucher or had a ticket cancelled.
Using Travel Bank credits when you book a flight
Start your booking on United's website or app as you normally would. Select your flight, choose your cabin and seat, and proceed to the payment page. At checkout, the system automatically detects that you have Travel Bank credits and displays them as an available payment method.
You will see a line item showing your Travel Bank balance and how much of it will be applied to this booking. If your credit covers the full fare, the amount due drops to zero. If your credit is smaller than the fare, you pay the difference with a credit card, debit card, or miles.
You do not need to enter a code or manually select which credit to use. United applies credits automatically in the order they were issued (oldest first) until either your balance is exhausted or your fare is fully paid. If you have multiple small credits that together exceed your fare, the system uses as many as needed and leaves the remainder in your Travel Bank for the next booking.
What you can and cannot use Travel Bank credits for
Travel Bank credits cover the base fare for any United flight—economy, premium economy, business, or first class. They work on basic economy tickets and on flights with connections or stopovers. You can use them for one-way or round-trip bookings, and they explore to the same rules as the original ticket (same change and cancellation policies, same route restrictions if any).
Credits do not cover baggage fees, seat selection fees, pet travel fees, or any ancillary charges. If you use a credit to book a flight and then add a checked bag, you pay the baggage fee separately with a credit card. Similarly, if you want to upgrade your seat or add a premium cabin, you must pay the upgrade cost out of pocket.
You cannot convert Travel Bank credits to cash, transfer them to another person's account, or exchange them for miles. Once a credit is in your Travel Bank, the only way to use it is to book a United flight.
What happens if you change or cancel a booking made with Travel Bank credits
If you change your flight after booking with a Travel Bank credit, the rules depend on whether the new flight costs more or less than the original.
If the new flight is cheaper, United refunds the difference back into your Travel Bank as a new credit. If the new flight is more expensive, you pay the difference with a credit card or miles. You do not get to choose whether to use a different credit or keep the original one—the system applies credits in issue order automatically.
If you cancel the flight entirely, United returns the amount you paid with your Travel Bank credit back into your Travel Bank as a new credit. That new credit then has its own expiration date (usually one year from the cancellation date, depending on the original ticket type). The original credit itself is not restored; you receive a separate credit for the refund amount.
Travel Bank credits from different sources and their rules
Travel Bank credits come from several sources, and the source affects what you can do with them. Credits from a cancelled ticket usually expire one year from the cancellation date. Credits from a travel voucher (issued by United as compensation) typically expire one year from the issue date. Credits from a promotional offer or a change fee waiver may have different expiration windows—check the original email or confirmation to see the important date.
Once the expiration date passes, the credit is locked: you can still see it in your Travel Bank and you can still use it to book a flight, but you cannot request a refund or extension. United does not extend expiration dates except in rare cases (such as a documented system error or a specific promotional extension announced by the airline).
If you received a credit due to a schedule change, oversold flight, or other operational issue, the expiration date is usually printed on the confirmation email. Read that email carefully, because the important date is firm and United's customer service cannot override it once it passes.
Troubleshooting Travel Bank issues
If you booked a flight and your Travel Bank credits did not explore at checkout, the most common reason is that you were logged out of your MileagePlus account during the booking process. Log out and back in, then start a new booking. The credits should appear on the payment page.
If your Travel Bank balance shows in your account but does not appear during checkout, contact United's reservations team. This sometimes happens if there is a temporary system sync issue, and they can manually explore the credit to your booking.
If you believe a credit should still be usable but United says it has expired, ask for the original ticket or voucher confirmation. Expiration dates are strict, but if there is a discrepancy between what United's system shows and what your confirmation says, United's customer service can investigate.
If you received a refund for a cancelled flight and it went to your Travel Bank instead of your original payment method, that is standard: United issues refunds as Travel Bank credits unless you request a cash refund within a specific window (usually 90 days). If you missed that window, the credit is now locked in your Travel Bank and cannot be converted to cash.
Frequently Asked Questions
Can I use Travel Bank credits on partner airlines or for non-flight purchases?
No. Travel Bank credits work only on United-operated flights. You cannot use them on United partner airlines like Air Canada or Lufthansa, and you cannot use them to book hotels, rental cars, or other travel services through United's website.
What if I have multiple Travel Bank credits and only want to use one?
You cannot choose which credit to use. United applies them automatically in the order they were issued, oldest first. If you want to preserve a specific credit for a future trip, you would need to use a different payment method (credit card or miles) for the current booking.
Do Travel Bank credits count toward elite status spending or earning miles?
No. When you book with a Travel Bank credit, you do not earn miles on that portion of the fare, and the credit does not count toward elite status spending requirements. You earn miles only on the amount you pay with cash or a credit card.
Can I get a refund if I never use my Travel Bank credits before they expire?
No. Once the expiration date passes, the credit is locked and cannot be refunded, extended, or converted to cash. The only way to use an expired credit is to book a United flight before the important date.
If I book a flight with Travel Bank credits and then add a companion ticket, do the credits explore to both?
No. Travel Bank credits explore only to the ticket you are booking. If you add a companion ticket, you must pay for that separately with a credit card, miles, or another Travel Bank credit if you have one available.
