To JetBlue’s surprise (but nobody else’s), the program was quite successful. The airline is taking advantage of the “while supplies last” comment in the promotion. Since the airline ran out of passes, it won’t keep the deal alive until Friday.
JetBlue does cite the realistic concern about seat availability: if too many people have passes, it could become impossible to accommodate everyone who’s entitled. Of course, the world is silent on whether oversized passengers need to buy two monthly passes, based on the growing airline trend regarding growing fliers.
