Anybody know the hours of the Qatar checkin counter at O'Hare? I note they have a 7:30pm flight and a 1:30am flight. Does the desk remain open between flights, or shut down until 10:30ish? I ask because I doubt we will be able to get QR boarding passes at our point of departure, since QR wants to check travel documents. Have a long layover and trying to figure out whether to hang out in T3 for several hours, or head directly to T5. Don't want to be stuck outside security in T5.
