JetBlue raises bag fees as oil prices soar. See how much you'll pay

• JetBlue has increased its checked bag fees, citing rising operating costs.
• The airline is the first U.S. carrier to raise bag fees in response to higher oil prices linked to the war in Iran.
• A first checked bag will now cost a minimum of $39, an increase from the previous $35 fee.

JetBlue raised its checked bag fees, citing higher operating expenses.

As the war in Iran drags on, skyrocketing oil prices have hit airlines' finances across the industry, but JetBlue appears to be the first U.S. carrier to raise bag fees as a result.

"As we experience rising operating costs, we regularly evaluate how to manage those costs while keeping base fares competitive and continuing to invest in the experience our customers value," the airline told USA TODAY in a statement. "Adjusting fees for optional services used by select customers, such as checked baggage, allows us to continue offering more competitive fares while delivering the onboard experience our customers love, including complimentary snacks and drinks, unlimited, high-speed Wi-Fi and seatback entertainment screens."

JetBlue passengers will now have to pay a minimum of $39 to check a bag, up from $35. Passengers who pay less than 24 hours before departure get charged an extra $10, and travelers who fly during peak periods around major holidays or over the summer also get charged a premium. The full schedule of checked bag fees is available on JetBlue's website.

Frequent flyer status holders, called Mosaic members at JetBlue, and those who have co-branded credit cards from the airline will still get to check their first bags for free.

Some JetBlue fares already include a checked bag. Bag fees on transatlantic flights start at $64 for basic economy ticket holders.

JetBlue did not immediately clarify if the new fees apply to existing reservations or only to new ticket purchases.

The airline's decision reflects broader economic uncertainty as the war continues. It's also reminiscent of the first bag fees charged by U.S. airlines.

American Airlines introduced checked bag fees in 2008, citing high oil prices.
