Traveler pro tips

It's unlikely your bags will be lost during travel. But there are are a few steps you can take to help reduce this risk:

Before going to the airport, remove all old bag tags.
If you're checking a bag, make sure you get to the airport early.
Keep your bag tag receipt. You should also take a picture of your bag and bag tag receipt together for your records.
Place your phone number or email on a luggage tag or inside the front pocket of your bag so if your bag tag is lost, we can contact you to confirm where to send it.
Use our bag tracker or a device like an AirTag to keep an eye on your bag.
Place medication, valuables and other essentials, like keys and your wallet, in the bag you plan to bring on the plane with you.

Save time at the airport by prepaying for your bags. If you’re traveling on a United or United Express flight within the U.S., you can use your miles to pay the baggage fees before check-in.
If your flight is canceled, you can request a refund for any checked bag fees. Visit our refunds page to find out more.
United Business^®, United First^®, and United Polaris^® business class seats come with free checked bags. If you upgrade to one of these cabins before you check your bags, you won't have to pay for them. If you're still assigned to United Economy when you check your bags, then you will have to pay bag fees.

Some customers don’t have to pay fees for checked bags. This only applies to United- and United Express®-operated flights. If you’re eligible for different types of exemptions, the larger one will apply.

Active U.S. military personnel and their dependents.

The benefits below apply only on United- and United Express-operated flights.

For most trips that include a connection, your checked bags will follow you to the last stop on your ticket. You'll need to go to baggage claim and re-check your bags if:
- You have a layover
- You make a connection that involves an overnight stay
- Your connecting flight departs more than 12 hours after you arrive at the airport
- You’re connecting to a trip on a separate ticket and the flight is not with a Star Alliance™ partner airline
- You’re traveling internationally but connecting to a domestic flight in your destination country
Usually, we keep checked bags on the same flight as the traveler. If we can't, we send your bags on the next flight with available space.
If you check a bag with our partner airlines for the first segment of your trip, they decide what bag fees apply. There may be an exception if United's code is used for the first flight on the ticket.
Fee waivers for MileagePlus Premier members or United MileagePlus Chase card members may not apply on our partner airlines.
For details and information about each partner airline, you can visit their website.
United follows the U.S. Department of Transportation regulations when setting bag fees.
- The airline for the first segment of your trip will set the bag fees for your entire trip. If you decide to make a change to your trip and use a different airline, the policies of the new airline will apply. The flight number assigned to the first segment of your trip will come from the first airline you used for your trip. If this airline is not United or United Express, different fees may apply.
- Bag fees are based on the date of ticketing and on the ticketed cabin. They're also based on the traveler's status or membership on the date of travel. Checked bag fees apply at any point where you check a bag.
- For a trip that includes one or more connections, checked bags go to the final stop on the ticket. The fee for checking a bag from your starting point to your last stop will apply. If your connection is to a different airline, you must recheck bags with the new airline. Checked bags can go to your last stop if your new flight is Star Alliance member airline operated.
- If you chose to have a layover, your checked bags will go to your layover point, where you can collect them. When you resume travel, you may check your bags again. Fees may apply.
- Certain airports may reject your luggage based on size, weight or number of bags.
