JetBlue has said it’s “not in a position to comment on any potential updates to its aircraft or their flying routes,” but that the airline is working with its pilots to improve the efficiency of its routes.
The company said last week that it was “reviewing its aviation portfolio to improve efficiency and performance.”
JetBlue CEO Tom Fitzgerald told investors that the company has also been working with regulators to improve its airworthiness and safety.
JetBlue’s decision comes after a number of other airlines announced last week they were suspending flights to certain airports in the U.S. over safety concerns.
In a press release Friday, JetBlue said it was suspending the flights of its Boeing 737 MAX and Boeing 777-300ER planes in both Minneapolis-St. Paul and Seattle and suspending the service of the 737 MAX in Chicago.
“We are not in a situation where we have a clear plan to resolve this issue and we cannot share it with the public right now,” Fitzgerald said.
On Thursday, United Airlines announced that it would suspend service between the Dallas-Fort Worth International Airport and Minneapolis-Saint Paul International Airport.
Last week, Delta Air Lines also announced that its flights between Atlanta and New York’s JFK airport were suspended.
United has since cancelled all flights to and from Minneapolis and Chicago.
