Has anyone used SW and ME on an inbound trip? I'm wondering if you had any trouble getting your baggage delivered to your room or if it happens just as smoothly as it does for "participating" airlines. I do understand that the participating airlines part is supposed to only matter on outbound flights. I just want to make sure that inbound does go smoothly. We won't be using ME on the return portion of the trip. Tried searching and didn't come up with anything. Sorry!
