NEW YORK (TheStreet) -- With demand for its premium Mint cabins on New York flights exceeding expectations, low-cost airline JetBlue (JBLU) has announced it will be adding Mint cabins to select routes from Boston, the airline's No. 2 destination after its hub at John F. Kennedy International Airport.

The new premium seats will be added to planes flying the  Boston to San Francisco route starting in March 2016, and the Boston-Los Angeles run in October 2016. The airline will also be offering Mint cabin flights out of Boston to Barbados on a seasonal basis starting in March.

Having previously only offered only coach-class seats, JetBlue unveiled the premium service, which includes lie-flat beds, private suites, 15-inch video screens, and a curated and customizable tapas-style menu along with other amenities, for its cross-country passengers in 2014. One-way Mint tickets between Los Angeles and New York's JFK, as well as flights between San Francisco and JFK, are currently being offered starting at $599 on JetBlue's website.

Mint offers the longest beds on any airline in the continental U.S. market at 6-feet, 8-inches, as well as the widest seats of any U.S. domestic flight. Those seats also feature a massage function, power outlets and USB ports.

Beyond the introduction of Mint to the Boston routes, JetBlue also said it will increase the number of daily Mint cabin flights flying the JKF-LAX and JFK-SFO routes. JetBlue also announced they will also be offering nonstop flights between Boston and Nashville, Tenn., and daily nonstop service to Fort Lauderdale, Fla., in the spring.
