Low-cost airline JetBlue is auctioning off more than 300 round-trip flights at their eBay store and, as of this posting, some still have opening bids of five or 10 cents. The flights mostly connect to and from major metro areas (NYC, Boston, Chicago) and vacation destinations (Northern/Southern California, Florida's vacation spots, Salt Lake City), with a total of 20 airports covered, while the six "mystery" vacation packages are already pulling higher bids. The flights initially present only a range of dates, but all the flights leave on Thursdays or Fridays and return on Sundays or Mondays, and specific times and flight numbers appear when a bid is placed. If you've got a spare day of vacation or personal time, it couldn't hurt to try and find a cheap use for it. If you place a bid or find a seriously good deal, share your find in the comments.
