I am looking to do DOH-IAD in few months time. Has anyone flown this route?
Do you get dine on demand/a la carte, or the usual trolley service? If it's the trolley, what do you get served given the outbound is a morning flight (brunch/snack/dinner I'm thinking) and inbound (supper, breakfast, lunch).

Have they started handing out pj's recently?
Do they provide limo drive/chauffeured car on arrival to IAD?
Which lounge does QR use in IAD?

Sorry if these questions have already been answered somewhere else. Thanks
