JetBlue will end its policy of allowing one free checked bag and will introduce three levels of bundled fares that are based on the number of bags passengers check: none, one or two bags.
The airline said it will implement bundled fares in the first half of 2015.
JetBlue will also reconfigure its cabins, installing new seats that will allow it to increase the number of seats on each flight. JetBlue says that even with the new configuration, it will continue to offer the most legroom in coach.
JetBlue will continue to offer free in-flight WiFi, which it plans to monetize through partnerships it is pursuing with Verizon, the Wall Street Journal and others.
Its entire Airbus A320 and A321 fleet will be equipped with Fly-Fi in the first half of 2015; it will begin installing Fly-Fi on its Embraer 190s after that.
Meanwhile, JetBlue will continue to add Mint premium service on flights from New York to San Francisco and Los Angeles. And, it will continue to offer premium economy seats with more legroom.
Southwest will become the lone U.S. carrier to allow free checked bags after JetBlue implements its policy change.
