NEW YORK, August 13 (RIA Novosti) - A U.S. discount airline has begun selling monthly "All-You-Can-Jet" passes on its domestic and international flights, according to JetBlue's website.
The monthly pass costs $599 and allows pass holders to fly to 56 of the company's destinations, including Mexico, Puerto Rico and other countries in the Caribbean.
In comparison, a monthly pass on the New York subway is around $100.
The company has also warned that if the demand for the monthly passes becomes too great, the company will halt sales. Should that happen, current pass holders would still be able to use their monthly passes.
