JetBlue is increasing bag fees — again. 

Checking a bag will now cost $50, up from $45, if paid for more than 24 hours before departure, and $60 within 24 hours. During peak travel periods, those fees rise to $55 and $70.

Earlier this year, most major U.S. airlines raised baggage fees. But JetBlue is the first to raise them twice. A spokesperson for JetBlue said the increases were in response to higher operating and fuel costs. 

“We’re adjusting checked bag fees to help offset rising fuel and operating costs,” the spokesperson said in a statement. “This helps us keep our base fares competitive while giving customers the choice to pay for a checked bag only if they need one.”

We’ve typically seen that when one airline increases baggage fees, others tend to swiftly follow. So don’t be surprised if checked baggage becomes even more expensive. 

The increases come on top of steadily rising fares, now up between 20% and 30% in the past few years. Executives aren’t trying to hide it: They say fare increases are still trailing overall inflation and that demand is holding up. But at some point it will be too much, and we’re watching closely for any signs of a slowdown.

On another note, I will be at our Skift Aviation Forum next week, November 12 at the TWA Hotel in New York City, so stop by and say hi. For more information on tickets, check out the banner below.
