Sorry to keep adding to the OP's check list

but you will ALSO want to SAVE YOUR ORIGINAL BOARDING PASSES!!! I really can't emphasize this point enough. Once your flights are done, scan them along with your ticket and email it Qatar Airways ASAP, that way they can start to follow up with it sooner rather than later
