Low-cost carrier JetBlue is now selling refundable fares, with a catch: they’ll cost fifty to over a couple hundred bucks more. A nonrefundable adult ticket from Buffalo, NY to JFK on Valentine’s Day, returning on Monday, will cost $69. Wanna upgrade to refundable? That’ll be $299 total please. At that premium, the prospect of getting a refund hardly seems worth it for most travelers. For airfare nerds, the new fares will be designated class Y, fares previously designated Y will now be class E. The airline is promoting the refundable tickets by giving quadruple TrueBlue points for tickets bought before February 13.
