Lots of companies offer promotions and giveaways through Facebook, so it’s completely plausible that JetBlue might be offering a free vacation if you share and like a photo or “like” their brand page. You should do a little checking before you hit “share,” though. Like making sure that the page you’re sharing really belongs to the brand.

Right now, as in this very afternoon, there’s a JetBlue spoof page blowing up Facebook. Don’t share it, don’t like it: there’s no Vegas vacation giveaway. Sorry.

Here’s a solid hint: the page says that “Holiday and hotels are all paid for with $2,000 spending money.” An American company like JetBlue probably wouldn’t say “holiday” — that’s U.K. English. They’d say “vacation.”

Also, the real JetBlue Facebook page has more than 700,000 “likes,” as befits an established airline. The fake one has about 1,000. It’s grown by 100 in the time it took me to write this post. Warn your family, friends, and frenemies.
