The arrival of Shake Shack in JFK International Airport's Terminal 4 on May 24 will be a celebration—especially since free burgers will be given away. From May 19-22, "free burger passes" will be distributed at Delta's T4X (376 West Broadway), granting customers the opportunity to save nearly $5. The downside is that the lines will be very, very long. The upside is obviously free Shake Shack.

You have a little less than a week to decide what's more important.
