JetBlue offers new 3-month unlimited flight pass

From Aug. 22 to Nov. 22, passengers can take an unlimited number of flights from Logan International Airport to any JetBlue city - 55 in all - for a flat rate of $1,999. For $1,499, Boston pass holders can fly to 13 nonstop destinations, mainly on the East Coast. The BluePass, aimed at business customers, is more flexible than the All You Can Jet pass, allowing travelers to book and change flights up to 90 minutes before departure.

Pass holders can also miss two scheduled flights in a week without being penalized. Access to seats with more legroom and priority boarding is not included.

The BluePass went on sale yesterday and will be available until Sunday, or until the passes sell out. The one-month All You Can Jet pass sold out within a few days both times the airline offered it.

JetBlue is also offering the BluePass to customers in Long Beach, Calif. Between 15 and 20 percent of JetBlue’s passengers are business travelers, and in Boston, that figure is significantly higher, said Dennis Corrigan, vice president of sales and revenue management.

“As we’ve been really building out the Boston network, and we’ve primarily focused on business destinations, it was just a no-brainer,’’ he said.

JetBlue fell 5 cents, or 1.1 percent, to $4.65 in Nasdaq Stock Market trading, the lowest closing since July 2009.

JetBlue added routes from Boston to Washington, D.C., and Newark in the past year and beefed up its schedule to Chicago, Baltimore, Raleigh, and Los Angeles.
