Travelling on UA from AMS to IAH, then connecting on a separate ticket at IAH to PHX on AA. Will there be a place in the international arrivals at terminal E to check my bags onward on AA (or, if UA will tag them through to PHX, to drop them off)? Or do I need to lug the bags from terminal E over to terminal A in order to check them for my onward AA flight? What's the mode of transportation landside from E to A? Bus?
