If you're planning a trip this summer, this one deserves a look as there won't be many more. For the most part, the carriers are now setting their sights on fall travel (it's no mistake that these discounts extend into early fall and come days after Southwest announced fall deals) and are just filling leftover spots with short-term sales like this one.
Anyway, this offer is good until midnight for travel from July 13-Oct. 5. Sale seats will not be available on all days or flights. Also note: Sale prices will only be available through the JetBlue site; you won't see them on Orbitz, Travelocity, Expedia, or Priceline. Here's the fine print, and some sample one-way fares from Boston:
Baltimore $34; Newark $39; Pittsburgh, Washington (Dulles) $44; Washington (Reagan) $49; Richmond, Va., $59; Charlotte, NC., $69; Jacksonville, Fla., $79; West Palm Beach or Tampa $89; Chicago $94; Bermuda or New Orleans $99; Phoenix $129; Austin $139; Aruba $164.
