As I wrote about first thing this morning, JetBlue is offering 25% off ALL flights from New York Airports (JFK, LGA, and EWR) for reservations made by 4pm EST TODAY!! This is for travel September 3 through October 31, 2013.
Flights must originate from New York, but can be one-way or roundtrip. Book at www.jetblue.cim/promo and enter promo code 2HOT2HANDLE. From the time this post was written, you have another hour and a half to book!
