United Airlines charges for checked bags on most tickets, but the fee depends on your ticket type and frequent flyer status

United Airlines charges $38 for the first checked bag and $48 for the second checked bag on most domestic flights. These are the standard fees as of 2024. However, you won't pay anything if you hold certain ticket types, elite frequent flyer status, or a United credit card. The fee applies per direction of travel, so a round trip means you could pay twice if both legs charge the fee.

The key is knowing which passengers get free checked bags. If you're flying on a basic economy ticket, you'll pay. If you're flying on economy, business, or first class, your checked bags are free. The difference between these ticket types affects more than just baggage — basic economy also restricts seat selection and carry-on bag space — so the checked bag fee is often part of a larger cost difference.

Key Takeaways

  • Standard checked bag fees are $38 for the first bag and $48 for the second on domestic flights, charged per direction of travel.
  • Economy, business, and first class tickets include free checked bags; basic economy tickets do not.
  • United MileagePlus elite members (Silver and above) and United credit card holders get free first checked bags regardless of ticket type.
  • International flights may have different baggage allowances and fees depending on your destination region.
  • Paying the fee at the airport costs more than paying online before your flight.

Who gets free checked bags

If you hold MileagePlus elite status at the Silver level or higher, your first checked bag is free on all United flights. This includes Silver, Gold, Platinum, and 1K members. Your when ready family members traveling on the same reservation also get the benefit. The second bag still costs $48 if you need it.

The United Club Infinite credit card and the United Explorer Card both include a free first checked bag benefit for the cardholder on all United flights. You don't need elite status to get this — it comes with the card itself. Other United credit cards (like the United Gateway Card) do not include this benefit, so check your specific card's terms.

If you're flying on a paid ticket in economy, business, or first class, checked bags are included at no extra cost. The only time you pay is if you're on a basic economy ticket or if you're checking more than two bags. Basic economy is United's lowest-cost ticket type and comes with restrictions on seat selection, carry-on bags, and checked luggage.

How much you'll pay and when

The standard domestic fee is $38 for your first checked bag when you pay online before your flight. If you wait and pay at the airport, the fee jumps to $50. The second checked bag costs $48 online or $60 at the airport. A third bag and beyond cost $200 each. These prices explore to flights within the continental United States.

International flights follow different rules depending on where you're flying. Flights to Canada, Mexico, and the Caribbean typically follow the same fee structure as domestic flights. Flights to Europe, Asia, and other distant regions often include a higher baggage allowance as part of the ticket, so you may get two free checked bags instead of one. Check your specific flight's baggage policy before booking.

The fee is charged per direction of travel, which means a round trip counts as two separate journeys. If you're flying from New York to Los Angeles and back, you could pay the first-bag fee twice — once on the outbound flight and once on the return — unless your ticket type or status covers it.

How to avoid paying the fee

The simplest way to avoid checked bag fees is to book a ticket type that includes them. When you search for flights on United's website, you'll see the ticket types listed: basic economy, economy, business, and first class. The price difference between basic economy and economy often comes close to the $38 checked bag fee, so comparing the total cost (ticket plus baggage) makes sense before you buy.

If you fly United frequently, the MileagePlus frequent flyer program offers free checked bags starting at the Silver elite level. You earn elite status by flying a certain number of miles or segments in a calendar year, or by spending money on United flights and the United credit card. The Silver level requires 25,000 elite may have access to miles or 30 paid segments in a year.

The United credit card route is faster if you don't fly often. The United Explorer Card costs $0 the first year and $95 per year after that, but it includes the free checked bag benefit when ready. If you check one bag per round trip and fly twice a year, the card pays for itself. The card also earns bonus miles on United purchases, which can offset the annual fee.

Paying the fee online versus at the airport

Always pay for checked bags online before you arrive at the airport. The fee is $38 online but $50 at the airport — a $12 difference per bag. You can add checked bags to your reservation on United's website up to 24 hours before departure. Log into your booking, find the baggage section, and select how many bags you want to check.

If you forget to pay online and realize at the airport that you need to check a bag, you'll pay the higher rate at the ticket counter. There's no way around this at the gate or baggage drop, so the best practice is to decide before you leave home and handle it on the website.

What counts as a checked bag

A checked bag is any piece of luggage you hand to the airline at the ticket counter or baggage drop and don't carry onto the plane. United's standard size limit is 62 inches (length plus width plus height) and 50 pounds. Bags larger than this or heavier than 50 pounds may be rejected or charged an oversized baggage fee of $200.

Your carry-on bag and personal item (purse, backpack, laptop bag) don't count toward the checked bag limit and don't cost extra. However, basic economy tickets restrict your carry-on to a personal item only — you can't bring a full-size carry-on bag. This is one reason basic economy is cheaper: you're paying less partly because you have fewer bags allowed.

Frequently Asked Questions

Do I have to pay for checked bags if I'm flying basic economy?

Yes, basic economy tickets do not include checked bags. You'll pay $38 online or $50 at the airport for the first bag. If you need to check a bag, upgrading to a regular economy ticket at booking time is often cheaper than paying the baggage fee separately.

Can I get a refund if I paid for a checked bag but didn't use it?

No, checked bag fees are non-refundable once you've paid them. If you change your mind about checking a bag, you cannot get the money back. Make sure you actually need to check a bag before you pay the fee online.

What if my bag is overweight or oversized?

Bags over 50 pounds or larger than 62 inches total dimension will be charged an additional $200 oversized baggage fee on top of the standard checked bag fee. Weigh and measure your bag before you arrive at the airport to avoid this surprise charge.

Do connecting flights count as separate journeys for baggage fees?

No, a connecting flight is one journey. If you're flying from New York to Los Angeles with a connection in Denver, you pay the checked bag fee once, not twice. The fee is charged per round trip or one-way ticket, not per flight segment.

Does my child need a separate checked bag fee?

Yes, each passenger — including children — is charged separately for checked bags. A family of four flying basic economy would pay $38 per person for the first checked bag, totaling $152 for one bag per person. Children do not get free or discounted baggage fees on United.
