US airlines collected $7.3 billion in baggage fees in 2024 according to the Bureau of Transportation Statistics, and 2026 projections suggest that figure will rise further as carriers refine their ancillary revenue strategies. The most significant policy change of the past year was Southwest Airlines ending its long-standing free checked bag policy in February 2025, a move that effectively erased the last holdout in what had become an industry-wide monetization shift. Understanding exactly what each airline charges, what triggers those charges, and how to legally minimize or eliminate them is now as consequential as knowing the base fare itself.

This guide compares every major US airline's baggage policy in 2026, with real numbers and actionable strategies to keep your total travel cost as low as possible. Before you book, search your route on Farefinda to compare fares across carriers and factor in these fees for an accurate total cost picture.

How to Read Your Total Fare Cost

Before comparing individual airline policies, it helps to understand how the fee tiers work. Almost all US airlines structure baggage fees in three tiers:

  • Personal item: A small bag that fits under the seat in front of you. Typically free on all carriers, including ultra-low-cost carriers.
  • Carry-on bag: An overhead bin bag. Free on full-service carriers, charged on most ultra-low-cost carriers.
  • Checked baggage: Bags in the hold. Charged by bag and by weight, with separate overweight penalties.

The critical error most travelers make is comparing headline fares without calculating total out-of-pocket costs including these fees. A $130 Frontier fare with a carry-on and checked bag can cost more than a $185 Delta fare where only a checked bag fee applies. Always calculate the all-in total, not just the ticket price, before deciding which airline wins on value. Farefinda makes it easy to compare base fares side by side so you can apply this math before booking.

American Airlines Baggage Fees 2026

American Airlines applies baggage fees based on fare class and AAdvantage status. For standard economy passengers with no status or co-branded card, the fees as of 2026 are:

  • First checked bag: $40 each way ($80 round trip)
  • Second checked bag: $45 each way
  • Third or additional bag: $150 each way
  • Overweight (51 to 70 lbs): $100 additional charge
  • Overweight (71 to 100 lbs): $200 additional charge
  • Oversized (over 62 linear inches): $200 additional charge

AAdvantage elite members receive checked bag fee waivers based on status tier. Holders of the Citi AAdvantage or Barclays AAdvantage co-branded credit cards also receive the first checked bag free when the card is used to purchase the fare. American's Basic Economy fare restricts passengers to a personal item only on most routes, making the overhead bin inaccessible without upgrading, which adds further complexity to the total cost calculation for budget-minded travelers.

Delta Airlines Baggage Fees 2026

Delta's fee structure is similar to American's, with a slightly lower first-bag charge:

  • First checked bag: $35 each way
  • Second checked bag: $45 each way
  • Third or additional bag: $150 each way
  • Overweight (51 to 70 lbs): $100 additional charge
  • Overweight (71 to 100 lbs): $200 additional charge
  • Oversized: $200 additional charge

Delta SkyMiles Medallion members receive checked bag fee waivers, and the Delta SkyMiles co-branded American Express cards provide the first checked bag free. Delta has significantly expanded its Basic Economy carry-on restrictions over the past two years. Passengers in Delta's Basic Economy fare class are now limited to a personal item on flights within the continental US, Hawaii, Alaska, Canada, and the Caribbean. According to the Bureau of Transportation Statistics, Delta ranked among the top three US carriers for total baggage fee revenue in 2024, collecting approximately $1.2 billion from checked bag charges alone.

United Airlines Baggage Fees 2026

United's checked baggage fee structure in 2026:

  • First checked bag: $40 each way
  • Second checked bag: $45 each way
  • Third checked bag: $150 each way
  • Overweight (51 to 70 lbs): $100 additional charge
  • Overweight (71 to 100 lbs): $200 additional charge
  • Oversized: $200 additional charge

United MileagePlus Premier members receive baggage fee waivers scaled to status level. United Explorer and Club Infinite Mileage card holders receive the first bag free. United has implemented its Basic Economy carry-on restriction broadly across its domestic and international network. Basic Economy passengers on United are limited to a personal item and must pay to bring any overhead bag, with gate charges applied at boarding to passengers attempting to board without the appropriate fare or bag fee paid.

Southwest Airlines: The End of Free Bags

Southwest's decision to end its "bags fly free" policy in February 2025 was among the most-discussed airline policy changes in recent years. For decades, Southwest's two free checked bags had been a genuine competitive differentiator that compelled other carriers to keep baggage fees in check on overlapping routes. That era is now over.

Southwest's current baggage fee structure as of 2026:

  • First checked bag: $35 each way
  • Second checked bag: $45 each way
  • Overweight (above 50 lbs): Fees apply at rates comparable to other major carriers

Southwest Rapid Rewards A-List Preferred and A-List members receive the first checked bag free. Rapid Rewards credit card holders also receive the first bag free when the card is used to purchase the fare. For Southwest passengers without status or a co-branded credit card, the airline is now priced similarly to American and Delta on the baggage dimension. The competitive advantage that once made Southwest the automatic recommendation for travelers who checked bags has largely disappeared from the market.

JetBlue and Alaska Airlines Baggage Fees 2026

JetBlue raised its first checked bag fee in 2025 and now charges:

  • First checked bag: $40 each way
  • Second checked bag: $50 each way
  • Overweight (above 50 lbs): $150 additional charge

JetBlue's Blue Basic fare restricts passengers to a personal item only, with carry-on bags charged separately at the gate. JetBlue Mosaic members and TrueBlue Plus credit card holders receive checked bag waivers.

Alaska Airlines offers a slightly more generous structure on the first bag fee:

  • First checked bag: $35 each way
  • Second checked bag: $45 each way
  • Overweight (51 to 100 lbs): $100 additional charge
  • Overweight (above 100 lbs): $200 additional charge
  • Oversized: $150 additional charge

Alaska Mileage Plan MVP, MVP Gold, and MVP Gold 75K members receive checked bag fee waivers. Alaska Airlines Visa cardholders receive the first bag free. Alaska is frequently underrated as a loyalty program for travelers on the West Coast. Its partnership with American Airlines allows cross-crediting of miles, adding meaningful flexibility for frequent travelers.

Budget Carriers: Spirit, Frontier, and Allegiant

Ultra-low-cost carriers operate on fundamentally different fee structures where almost every element of the travel experience is unbundled and sold separately.

Spirit Airlines emerged from its second bankruptcy in 2025 with a reduced network and revised fee structure. Current fees vary by route and by when they are purchased, with early purchases at booking significantly cheaper than gate charges:

  • Carry-on bag: $45 to $85 depending on purchase timing
  • First checked bag: $50 to $90 depending on route and timing
  • Overweight (above 50 lbs): $100 additional charge

Frontier Airlines applies a similar architecture:

  • Carry-on bag: $49 to $89 depending on purchase timing
  • First checked bag: $49 to $89 depending on route and timing
  • Overweight fees: Apply above 50 lbs at comparable rates

Frontier's discount club memberships, sold as annual subscriptions, reduce baggage fees significantly for travelers who fly Frontier multiple times per year. For regular Frontier customers, the membership often pays for itself within two round trips.

Allegiant Air operates between secondary city pairs and applies fees at every stage of the booking. Key differences from other carriers:

  • Carry-on bag: $20 to $50 depending on route and purchase timing
  • First checked bag: $40 to $75
  • Overweight (above 40 lbs): $75 additional charge

Allegiant's weight limit for checked bags is 40 pounds, not the industry-standard 50 pounds. This lower threshold catches travelers off guard and generates significant fee revenue from passengers who pack expecting the standard allowance. Weigh your bag before arriving at an Allegiant counter.

Carry-On Rules Are Tightening Across the Industry

A meaningful shift in 2026 is the tightened enforcement of carry-on bag size rules across the industry. Airlines have always had stated overhead bin size limits, typically 22 by 14 by 9 inches, but enforcement was historically inconsistent. That is changing in visible ways at airports across the country.

American, Delta, United, and JetBlue have all reported increased gate agent enforcement of size limits, particularly on high-load flights where overhead bin space is genuinely constrained. Bags that previously passed through unquestioned are now being gate-checked more frequently. On carriers with Basic Economy restrictions, gate-checking a bag that should have been paid for triggers a charge at the gate, often higher than the advance purchase price would have been.

The Federal Aviation Administration does not regulate carry-on bag size, leaving that entirely to individual airline policy and gate agent discretion. The practical risk of being charged for an oversized carry-on is higher in 2026 than in any prior year in recent memory. Travelers who routinely test the limits of "carry-on size" bags should be prepared for this new enforcement reality.

How to Avoid Baggage Fees Legally and Completely

The most effective strategies for minimizing or eliminating baggage fees in 2026:

Use a co-branded airline credit card. Every major US carrier offers a co-branded credit card that includes the first checked bag free as a core benefit. Annual fees on these cards typically range from $95 to $550, and the first-bag waiver alone can justify the annual fee for travelers who check bags on two or more round trips per year. The Citi AAdvantage Platinum card, Delta SkyMiles Gold American Express, and United Explorer card are the most widely used entry-tier options. Purchase your ticket with the card to activate the waiver.

Pack into a personal item only. For short trips, fitting everything into a bag that slides under the seat eliminates baggage exposure entirely. Purpose-designed travel backpacks from brands like Osprey, Peak Design, and Tortuga are engineered to maximize the personal item footprint. A well-packed 20-to-25-liter backpack holds several days of clothing and eliminates every baggage fee on every carrier.

Ship your luggage ahead. Services like Luggage Forward and Ship Smart allow you to ship checked bags ahead of your arrival. On international trips where checked bag fees approach $75 to $100 each way, shipping is frequently cost-competitive, with the added benefit of bypassing airport check-in entirely. Book shipping at least 48 hours before departure for reliable delivery.

Buy bundled fares that include bag allowances. Most airlines now offer fare bundles (often labeled "Comfort," "Plus," or "Flexible") that include a checked bag in the ticket price. The bundled fare is frequently only $20 to $40 more than the Basic Economy base fare, making it a genuine value when you factor in what the standalone bag fee costs. Compare all fare tiers, not just the cheapest listed price, before deciding what to book. Start your fare comparison on Farefinda to see all options side by side and pick the tier that works for your travel profile.

Achieve elite status or leverage partner benefits. Airline elite status provides baggage fee waivers on most carriers, and many extend that waiver to companions on the same booking. Even mid-tier status on a program you fly regularly can save $150 to $300 per year in bag fees alone, often representing one of the highest tangible-value status benefits outside of upgrades.

Baggage Fees Quick Reference: All Major Carriers

Here is a consolidated comparison of first and second bag fees for quick reference when you are comparison-shopping fares. All figures are per bag, each way, for standard economy passengers with no status or co-branded card:

  • American Airlines: Bag 1: $40 | Bag 2: $45
  • Delta Air Lines: Bag 1: $35 | Bag 2: $45
  • United Airlines: Bag 1: $40 | Bag 2: $45
  • Southwest Airlines: Bag 1: $35 | Bag 2: $45
  • JetBlue Airways: Bag 1: $40 | Bag 2: $50
  • Alaska Airlines: Bag 1: $35 | Bag 2: $45
  • Spirit Airlines: Bag 1: $50 to $90 (variable) | Carry-on: $45 to $85
  • Frontier Airlines: Bag 1: $49 to $89 (variable) | Carry-on: $49 to $89
  • Allegiant Air: Bag 1: $40 to $75 (variable) | Carry-on: $20 to $50

Weight limits are 50 lbs for all carriers listed above except Allegiant (40 lbs). Overweight charges apply above the limit at $100 to $200 per bag depending on the carrier. Always prepay bags at booking rather than at the airport to access the lowest fee tier on every carrier.

Frequently Asked Questions

How much do airlines charge for checked bags in 2026?

For the major US full-service carriers, first checked bag fees range from $35 to $40 each way. The second bag runs $45 each way on most carriers. Ultra-low-cost carriers like Frontier and Allegiant charge $49 to $90 per bag depending on when the fee is purchased, with gate purchases being the most expensive. Southwest, formerly the only major carrier with two free checked bags as a default policy, now charges $35 for the first bag following its policy change in February 2025. According to the Bureau of Transportation Statistics, total US airline baggage fee revenue reached $7.3 billion in 2024.

Which airlines still offer free checked bags in 2026?

No major US airline currently offers free checked bags across all fare classes as a universal default. Several airlines waive the first checked bag fee for co-branded credit card holders and elite loyalty members. Hawaiian Airlines includes a bag allowance on certain inter-island and long-haul fares, and some international routes on American and United include a bag allowance by default depending on the fare class and destination. Military personnel traveling on orders receive baggage fee waivers on all major US carriers under federal requirements.

Is it cheaper to prepay my bag or pay at the airport?

Always prepay your bag at the time of booking or at least before check-in begins. Airlines price gate charges at a premium compared to advance purchase fees, typically $5 to $45 more per bag depending on the carrier. Spirit and Frontier have the most dramatic gap between advance and gate pricing, with some routes showing gate charges that are nearly double the advance purchase price. Prepaying also eliminates the risk of being turned away if space runs out in the hold on a capacity-constrained flight.

What happens if my bag is overweight?

Overweight fees apply above 50 lbs on most US carriers (40 lbs on Allegiant). The fee is typically $100 for bags between 51 and 70 lbs, and $200 for bags between 71 and 100 lbs. Bags above 100 lbs are generally not accepted as standard checked luggage and must be shipped as cargo through separate arrangements. The most cost-effective way to avoid overweight fees is to weigh your bag before leaving for the airport. A luggage scale costs around $10 to $20 and pays for itself the first time you avoid a $100 overweight charge.

Does booking with a travel credit card like Chase Sapphire cover baggage fees?

General-purpose travel cards like the Chase Sapphire Preferred and Reserve do not waive baggage fees directly. However, the Chase Sapphire Reserve and Amex Platinum offer annual airline fee credits of $300 and $200 respectively that can often be applied toward baggage charges when fees are paid directly with the card. Co-branded airline cards are more direct: the first bag fee is waived automatically when the airline's co-branded card is used to purchase the ticket. For travelers who check bags regularly, a co-branded card paying for itself purely through bag waivers is the most straightforward path to eliminating this fee category entirely.
