I flew to Phoenix on holiday yesterday with my Phantom in it's tradecraft case. I placed it in the overhead bin and settled back for the sardine ride to Sky Harbor from New York. When I arrived 4 hours and change later I pulled it out and discovered the case was sucked in till it hit the top of the quad! Keep in mind these cases are water and dust proof. I had to pry that sucker open! Fortunately I don't see any damage. I never considered that happening since the cabins are pressurized. Take a look at the photos...
FYI - The case would not fit in the short way. I had to put it length-ways. I should of tried it backwards but it was congested in the isle and I also had my dog with me so I just stuck it sideways and closed the bin. Southwest has a very generous carry on size limit by the way.
No issues at security. The ladies were busy fawning over my dog and the guys were asking me questions about the Phantom.
UPDATE - SOLUTION BELOW
