Since all of the cargo growth is international, the outsourcing trends will put a big damper on any kind of growth at UPS. This is just my opinion and I hope I'm wrong, but I see the writing on the wall. As far as growth of the airline at UPS, I think it about as big as its going to get. Future growth will be primarily from US to international destinations as foreign country point to point flying will probably be done by other contracted carriers.
I'm not a doom and gloom guy by any stretch of the imagination, but I see this as simple reality.
