The largest seasonal airline at Martha’s Vineyard Airport is pushing back the start of its flights by several weeks this year. 

JetBlue will not start its summer schedule until June, with flights to Washington, D.C. beginning on June 12 and flights to New York starting on June 26. The New York schedule is about a month later than usual.

“It is a later start,” said Geoff Freeman, the airport manager. “Usually they start around Memorial Day or a little before.” 

JetBlue carries the most summer passengers of the three large seasonal airlines. In 2024, running from May through October, JetBlue transported just over 32,000 passengers on flights to and from the Vineyard. 

For comparison, that’s more than the other two airlines combined; Delta carried 17,379 passengers and American carried 14,364. 

This year JetBlue is also planning to cut back on the number of flights, though that likely won’t result in fewer passengers because the airline is bringing on a new, large airplane. 

In past years, JetBlue has flown a 100-passenger plane. That one is being phased out in favor of a 140-passenger aircraft. 

“That’s why you are starting to see some flight reduction,” Mr. Freeman said. 

JetBlue will fly to the Vineyard from D.C., JFK International Airport in New York and Boston. The schedule is anticipated to run through the end of October. 

Delta is starting up its flights to LaGuardia and JFK on May 22 and will end on Sept. 7. American Airlines usually starts towards the end of June and runs through Labor Day, but that schedule still needs to be finalized, according to Mr. Freeman. 

Mr. Freeman said the airport is not involved with the airlines’ scheduling decisions. Flight schedules often shift from year to year, depending on demand, workforce size and other factors.
