I don't fly nearly as much as you so 'no' from me - but sounds like a change from J to F might make things bearable?
Someone else in this thread mentioned pre GFC a lof more companies sending folks J, now many more are stuck in Y and I think it makes a difference. The various beancounters just see the added cost, but I think what they are not factoring in is that very frequent flyers will eventually 'hit the wall' as it seems you may have done.
When that happens is different for all of us, but companies need to be extremely wary of this as its hard to motivate a worn out road warrior once he hits that block - best to keep them as comfortable as possible to reduce the chance of ever getting there.
First class =) i can only dream, but yes you are right, the bean counters dont understand that all this travel is actually quite tiring...
I use to fly up to Chicago for the weekend but this time I just lay around in Cincinnati...
