JetBlue eliminates unprofitable routes and adjusts Europe flight schedules.

• JetBlue has been focused on cutting unprofitable flights to stem losses.
• The carrier also has been trimming underperforming routes to focus on core markets.
• JetBlue is discontinuing some Miami flights and announced that they will have excess staff in that location.

The airline announced on Wednesday that it will eliminate unprofitable flights, relocate aircraft equipped with high-value business class, and adjust its European service in an effort to achieve consistent profitability and reduce expenses.

Mint business class will no longer be available on Seattle flights in April.

JetBlue announced that it will discontinue flights from Fort Lauderdale, Florida, to Jacksonville, Florida; from John F. Kennedy International Airport in New York to Austin, Texas; Houston, Texas; Miami; and Milwaukee, Wisconsin; and from Westchester, N.Y., and Milwaukee. Additionally, the airline will end its service to San Jose, California.

JetBlue stated that discontinuing its service between JFK and Miami would result in an overstaffing situation in Miami, and it is currently collaborating with crew members to explore alternative work options, such as serving other cities.

Despite being a strong geography for JetBlue, we haven't been profitable in Miami post-COVID due to the dominance of legacy carriers like American and United, according to JetBlue's vice president of network planning and airline partnerships, Dave Jehn, in a staff note seen by CNBC.

It will continue serving Miami from Boston.

JetBlue will announce new Europe services next week, but it will drop its second JFK-Paris flight and its summer-only service between New York and London's Gatwick Airport starting in the summer 2025 travel season, said Jehn.

JetBlue's revenue and bookings have exceeded expectations for November and December, resulting in a more than 8% increase in share prices on Wednesday. As the company grapples with a Pratt & Whitney engine grounding and shifting post-pandemic demand, CEO Joanna Geraghty and her team are focusing on reducing costs and cutting unprofitable routes, such as those on the West Coast.

Customers impacted by JetBlue's changes can choose alternative flight options or obtain a refund if no other routes are accessible.

JetBlue announced that it recently made network adjustments in certain markets, removing underperforming flying from its schedule, in order to redeploy resources, including its popular Mint service, toward high-demand markets and new opportunities.
