More US airlines raise baggage fees: See the list

America’s biggest airlines have all increased their fees for checked baggage amid soaring jet fuel prices. 

Jet fuel costs have more than doubled in the nearly seven weeks since the U.S. and Israel started a war with Iran. Fuel is typically the second biggest expense for airlines after labor.

JetBlue was the first U.S. airline to announce baggage fee hikes, with United following suit the same week. Since then, American, Delta and Southwest have also increased bag fees. Here’s the latest: 

American Airlines

Effective April 9, American Airlines is increasing its checked bag fees by $10. 

Prepaid checked bags will be $45 for the first one and $55 for the second. If you pay at the airport, it’ll be $50 for the first and $60 for the second. A third checked bag will cost $200, a $50 increase. 

JetBlue Airways

JetBlue Airways is increasing baggage fees by $4 to $9 for economy travelers.

For flights within the U.S., Caribbean, and Latin America, the first checked bag will now cost $39 during off-peak travel (up from $35) and $49 during peak periods (up from $40). Travelers who pay less than 24 hours before departure will still incur an additional $10 fee.

Passengers with qualifying JetBlue co-branded credit cards or elite frequent flyer status will continue to be exempt from baggage fees.

United Airlines 

United Airlines raised checked bag fees by $10 to $50 for travelers purchasing tickets starting April 3.

Prepaid bag fees are now $45 for the first bag, $55 for the second and $200 for the third. 

Bags paid within 24 hours of travel are now $50 for the first, $60 for the second and $200 for the third. 

Eligible passengers — such as United Chase credit card holders, MileagePlus Premier members, active military members and travelers in premium cabins — can still check a bag for free. 

What they're saying:

"The reality is, jet fuel prices have more than doubled in the last three weeks," United CEO Scott Kirby wrote in a memo to employees in March. "If prices stayed at this level, it would mean an extra $11B in annual expense just for jet fuel. For perspective, in United’s best year ever, we made less than $5B." 

Despite soaring fuel costs and higher plane fares, Kirby said in March that "demand remains the strongest we've ever seen."

Delta Airlines 

For tickets purchased after April 8, Delta is increasing checked bag fees by $10 to $50. 

That means it will be $45 for the first bag, $55 for the second bag and $200 for the third. The fees apply to both domestic and select short-haul international routes. There are no changes to longer international flights.

Delta SkyMiles Medallion Members; customers traveling in First Class, Delta Premium Select and Delta One; active-duty military customers, and those with eligible co-branded Delta SkyMiles American Express Cards will still get one free checked bag, according to Delta. 

Southwest Airlines

Southwest is raising its fees to $45 for the first checked bag and $55 for the second, up $10 from when Southwest first started charging for checked bags less than a year ago. 

Active military, A-List Preferred customers and passengers who pay for Choice Extra fare can check up to two bags for free.

A-List customers and Rapid Rewards credit cardholders get one free checked bag.
