I suppose you have your reasons (Global ATM alliance?), but if you’re paying monthly fees on your US chequing accounts, for most people it’s worth shopping around.
leaving the US next month anyways. When I went to shop around, I was told small local banks don't do international wires, I didn't try the other big ones.
My credit union (First Tech) does wires. It goes through another bank, but they allow me to initiate it from my account etc, so there's no practical difference.
