United Airlines Checked Baggage Policy: Fees & Free Bag Tips

United Airlines' checked baggage policy varies significantly by fare type, route, elite status, and credit card. The gap between Basic Economy and standard Economy is especially large — not only in checked bag fees, but in carry-on restrictions that make Basic Economy a trap for travelers who don't read the fine print.

United Domestic Checked Baggage Fees

On domestic US routes, United's checked baggage fees by fare class:

• Basic Economy: $35 for the first checked bag, $45 for the second. Additionally, Basic Economy passengers may only bring a personal item into the cabin — no full-size carry-on in the overhead bin. This is the most restrictive fare class offered by any major US carrier.
• Economy (standard) and above: $35 for the first checked bag, $45 for the second.
• Business Class / United Polaris (domestic): Checked bags are included.

Third bag: $150 on domestic routes. Fees beyond the third bag vary by route.

United International Checked Baggage

United's international checked baggage policy is more generous:

• Economy on most long-haul international routes (Europe, Asia, Pacific, South America): One free checked bag included.
• United Economy on trans-border (Canada, Mexico, Caribbean): May not include a free bag — confirm at booking.
• United Business (Polaris) internationally: Two free checked bags, each up to 70 lb (32 kg).
• United First (domestic long-haul): Two free checked bags.

International free bag allowances make United economy transatlantic fares significantly more competitive than their domestic economy pricing suggests.

Basic Economy: The Hidden Restrictions

United Basic Economy is a distinct product that deserves special attention:

• No overhead bin access. Basic Economy passengers are limited to one personal item that must fit under the seat in front of them. The personal item limit is approximately 9 × 10 × 17 inches.
• No same-day changes and no standard upgrades.
• Checked bag fee applies as normal ($35 first bag) — you pay to check, and you cannot bring a carry-on into the cabin.

This combination — pay to check and no carry-on — makes Basic Economy the most expensive fare class per effective luggage allowance. A traveler with a standard rolling carry-on must either pay to check it ($35+) or purchase a higher fare class. Always compare total trip cost including bags before booking Basic Economy.

Premier Elite Status Baggage Benefits

United Premier Medallion status waives checked bag fees on United-operated flights:

Premier Status	Free Checked Bags
Premier Silver	1 free checked bag
Premier Gold	2 free checked bags
Premier Platinum	3 free checked bags
Premier 1K	3 free checked bags

Premier members also receive baggage benefits for companions traveling on the same reservation in many cases — verify United's current elite benefits for companion eligibility.

Chase United MileagePlus Credit Card Benefits

Chase United co-branded cards offer checked bag benefits:

• United Explorer Card, United Quest Card, United Club Card, United Club Infinite Card: The primary cardholder and one companion on the same reservation receive the first checked bag free on United-operated flights when the ticket is purchased with the card.
• Annual savings: $35 × 2 trips × 2 travelers = $140 per year, which can exceed the card's annual fee on its own.

The free bag benefit applies to the primary cardholder and one companion per reservation. The ticket must be purchased with the qualifying card — splitting the booking or using a different payment method may forfeit the benefit.

United Baggage Weight Limits

Weight	Fee
Under 50 lb (23 kg)	Standard fee applies
51–70 lb (24–32 kg)	$100 overweight fee
71–100 lb (33–45 kg)	$200 for first bag; $100 for additional bags
Over 100 lb (45 kg)	Not accepted as standard checked baggage

United's overweight fees apply per bag and are charged in addition to the standard checked baggage fee. A 65 lb bag on a domestic route costs $35 (standard) + $100 (overweight) = $135 total.

United Baggage Size Limits

United's maximum size for standard checked bags is 62 linear inches (length + width + height combined):

• Oversize fee (over 62 linear inches): $200 per bag, each direction.
• Maximum accepted size: 115 linear inches. Bags over 115 linear inches are not accepted as checked baggage.

Sports Equipment

United treats most sports equipment as standard checked bags subject to the 50 lb weight and 62 linear inch size limits, with standard fees. Oversized or overweight sports equipment incurs the applicable oversize ($200) or overweight ($100/$200) surcharges.

• Golf clubs: Standard checked bag fee; must be in a hard or soft case.
• Skis and snowboards: Standard checked bag fee; ski bag containing skis, poles, and boots counts as one checked item.
• Surfboards and oversize items: Oversize fee if over 62 linear inches.

How to Avoid United Checked Bag Fees

1. Get the United Explorer Card or higher. The card pays for itself quickly if you fly United with a checked bag even once per year. The Explorer Card's annual fee is offset by the first-bag benefit in a single round trip.

2. Book standard Economy, not Basic Economy. Basic Economy costs less upfront but often costs more in total once you account for needing a checked bag (because you have no overhead bin access for your carry-on).

3. Fly on international routes. Most United economy fares to Europe, Asia, and South America include a free checked bag — removing the fee that applies on domestic routes.

4. Earn Premier status. Even Premier Silver (the entry tier) waives the first bag domestically and earns benefits across Star Alliance partners when you travel internationally.

5. Carry-on only. United's carry-on allowance is one bag (22 × 14 × 9 in) plus one personal item for Economy and above. Basic Economy, as noted, only allows a personal item — so carry-on only only works if you are not on Basic Economy.

6. Pack under 50 lb. Distribute heavier items into your carry-on or personal item to avoid the $100 overweight fee on bags between 51–70 lb.

United vs. Delta vs. American: Key Differences

United and Delta have essentially equivalent domestic checked bag fees ($35 first bag, $45 second). American Airlines charges $35 for the first bag on most domestic routes but has a notably higher overweight surcharge ($150 at 51 lb vs. $100 at United and Delta). United's Basic Economy is distinctive for its no-overhead-bin restriction — Delta and American Basic Economy allow a carry-on.

Summary: United Checked Baggage at a Glance

On domestic US routes, United charges $35 for the first checked bag and $45 for the second. Basic Economy adds the extra restriction of no overhead bin carry-on access. International economy routes include one free bag. Chase United cardholders and Premier status members get the first bag free on domestic flights. Weight limit is 50 lb; the overweight fee is $100 for 51–70 lb and $200 for 71–100 lb.
