It's a good question. I saw some spending data, recently, showing that travel is way down. That might also be related to concerns about planes falling apart or catching on fire midair. 

 I'll admit that I am trying to avoid flying.  I hate security and I don't trust the safety of the planes or the pilots. 

 We already avoided it because of TSA and how unpleasant it is to fly with an energetic little kid. Actual safety concerns are just the icing on the cake.
