Jet Blue recently offered a special month-long “all-you-can-jet” pass for purchase, allowing buyers unlimited travel between 9/8 and 10/8 for the low price of $599. Worth it?

Two friends think so. Clark Dever and Joe Dinardo are milking this deal for all it’s worth, crisscrossing the country and spending only 12 hours in each city before hopping the next flight. Talk about getting your money’s worth.

Perhaps the bigger issue here is the marketing strategy. Jet Blue has gotten quite a bit of publicity over this gimmick. And the pass itself sold out early, thanks in large part to Twitter. The promotion sold out 36 hours before the deadline, once Jet Blue’s tweet went viral. Proof positive that tweeting can lead to tangible revenue results.
