We'll be flying CAI - AMM - DOH - BOS on our first middle east trip. The CAI-AMM-DOH legs of the trip are on RJ Business class and DOH-BOS in the QSuites.
When I check in for our flight home in CAI, will I get my boarding passes for all 3 legs of the trip even though they are on different airlines? I want everything to be smooth and not have to worry about check in at DOH.
Also, will we have to go through security and customs in AMM and DOH? our layover in AMM is 2 hours, 45 minutes and our layover in DOH is 4 hours, 15 minutes. I'd like to be able to access the Qatar business lounge.
