Ask, the Interstate, ICX and ATI guys how it worked out with them at UPS. Don't forget Challenge Air Cargo either. If, A big if, Amazon goes on it's own, they will pick whom they want no matter whom you work for. I also assume they will want no union on the property nor union people. I do not see it happening as they will have to pay top dollar vs. keep the fighting amongst the contractors.

Go read all about the regionals and the whipsawing. Airline bidness 101. That Amazon guy is ruthless.
