Which Airlines Have the Cheapest Checked Bag Fees in 2026? 

In 2026, Alaska Airlines and American Airlines offer the cheapest checked bag fees among major US carriers, starting at around $35 when prepaid online. No major US airline checks a bag for free anymore after Southwest ended its free-bag policy in 2025. International carriers like Emirates, Qatar Airways, and Singapore Airlines include a checked bag on most long-haul economy fares.

April 2026 marked a turning point for air travelers. Citing surging jet fuel costs, United Airlines, Delta, Southwest, and American Airlines all raised their checked baggage fees simultaneously pushing the US average first-bag fee to $45–$50. For a family of four on a round trip, that’s potentially $360 in bag fees alone, before you’ve set foot on the plane.

What Are the Cheapest Checked Bag Fees Among US Airlines in 2026?

Alaska Airlines and American Airlines charge the lowest first-bag fees of any major US carrier in 2026, starting at approximately $35 when prepaid online. Most other legacy carriers Delta, United, and Southwest start at $45 prepaid. Ultra-low-cost carriers like Frontier and Spirit use dynamic pricing that can push first-bag fees well above $60.

Here’s the full ranking table, sorted from cheapest to most expensive for the first checked bag on domestic routes:

Fees are per bag, per person, each way. Prices reflect 2026 rates sourced from airline websites and updated travel data (Deep Arrival, Trips With Tykes, June 2026).

One edge case worth noting: JSX offers free bags across the board, but it operates as a premium charter service with fares far higher than standard airlines the “free” bags are baked into the ticket price.

How Do Legacy Carrier Bag Fees Compare to Budget Airline Bag Fees in 2026?

Legacy carriers (American, Delta, United, Southwest) charge a flat, predictable fee starting at $35–$45 for a first bag prepaid online. Budget carriers (Spirit, Frontier, Allegiant) use dynamic pricing, meaning the same bag on the same airline can cost anywhere from $30 to over $99 depending on your route, fare class, and how early you pay.

This is where travelers get caught out. Frontier’s fee can look competitive at $59 prepaid but Frontier also sets its overweight limit at just 40 lbs, not the industry-standard 50 lbs. A standard packed suitcase often hits that threshold, triggering an additional $75–$100 overweight fee that most competitors wouldn’t charge.

How Much Is Extra Baggage on International Flights in 2026?

On most long-haul international economy flights, a checked bag is already included in the ticket price. Airlines like Emirates, Qatar Airways, Singapore Airlines, Japan Airlines, Turkish Airlines, and Virgin Atlantic include at least one checked bag on transatlantic and transpacific routes. The exception is basic economy or “light” fares, which strip the baggage allowance.

For international budget carriers, you pay separately. Norwegian Air charges $19–$45 for a first checked bag on international routes making it one of the more affordable options for transatlantic travel with luggage. Icelandair’s Economy Light fare does not include a checked bag; their Economy Standard and Economy Flex fares do.

Which Airline Credit Cards Give You a Free Checked Bag?

Most US airline co-branded credit cards waive the first checked bag for the cardholder and all passengers on the same reservation. With a typical annual fee of $95–$150, a single round trip with one bag can pay off the card entirely making airline credit cards one of the highest-ROI travel tools available.

Here’s how the math works on a round trip for two people:

• Two first bags, each way = 4 bag fees
• At $45 per bag = $180 in total bag fees
• Card annual fee = ~$99–$150
• Net savings = $30–$80 on just one round trip

Top airline credit cards for free checked bags (2026):

• Delta SkyMiles® Gold American Express Card  Free first bag on Delta, ~$150 annual fee
• United℠ Explorer Card  Free first bag on United, ~$95 annual fee
• Citi® / AAdvantage® Platinum Select® Card  Free first bag on American, ~$99 annual fee
• Alaska Airlines Visa® Credit Card  Free first bag on Alaska, ~$75 annual fee
• JetBlue Plus Card  Free first bag on JetBlue, ~$99 annual fee

Important rule: Most cards require that you book the flights using that specific credit card. For Southwest, simply holding the card is sufficient booking method doesn’t matter. Always confirm the cardholder’s name matches the reservation.

How Can You Get the Cheapest Possible Checked Baggage Fee?

The single most effective strategy is to prepay your bag online never at the airport. United Airlines, for example, charges $45 prepaid, $50 in the lobby, and $75 at the gate for the same bag. That $30 gap is the price of procrastination.

Five practical strategies to reduce or eliminate bag fees:

• Prepay online: Always cheaper than paying at check-in or the gate
• Use an airline credit card: Covers the bag fee for you and your travel companions
• Travel with a personal item only: Free on every airline, including ultra-low-cost carriers
• Book higher fare classes or bundles: Many airlines include a bag in Standard or Flex fares
• Take advantage of free gate-check offers: When overhead bins are full, airlines often check bags for free at the gate

What Is the Best Inexpensive Luggage for Avoiding Bag Fees?

The best inexpensive luggage for avoiding bag fees is a compact personal item bag one that fits under the seat in front of you (typically within 18 x 14 x 8 inches). Flying with a personal item only is free on every airline and completely eliminates checked bag fees on short and medium-haul trips.

If you occasionally need more space, look for soft-sided carry-ons that compress easily and meet the standard overhead bin dimensions (22 x 14 x 9 inches on most US carriers). Rigid carry-ons with expansion zippers are a common mistake they’re more likely to be gate-checked if the bin is full, sometimes at a fee.

What Should You Know About Southwest’s Bag Policy After 2025?

Southwest ended its legendary two-free-bags policy in 2025 a change that shocked its loyal customer base. Since April 2026, Southwest charges $45 for a first bag and $55 for a second, aligned with Delta. The only way to fly Southwest with a free checked bag now is with the Southwest Rapid Rewards® credit card or elite status.
