I am Platinum too. The airlines seems to take this charge of collusion pretty seriously. I would think it certainly is happening but not in an overt way. All the airlines know that if they all raise prices and do not increase capacity while fuel prices are low that SHAZAM!: we all get to make some big bucks. Not very hard to understand.
Howdy cornfedcowboy - I think you hit on the key word “capacity”
