Never flown QR before, looking at an itinerary now with a couple options, which leads me to a couple questions.

1) What's the best economy experience in the fleet? I've got options of 380, 77W and 350 (I think both 900 and 1000). Basically I'm looking at BKK-USA/Canada, I don't necessarily care where I arrive to, I've flown 380s before, I'd like to fly one again, but not if it's an inferior economy product.

2) Also having never flown through Doha, I'm looking at a couple things, I can do like a 24/48 hour stopover and explore a bit, which I'm favouring (even though it'll be insanely hot in August). But if I bail on that option there's layovers of 2/3/8 hours. I've got priority pass but I'm not sure if it's worth spending 8 hours in DOH even with lounge access. I like airports and my time isn't really worth anything so if it's an airport worth really exploring (seems like it is) I don't mind being there for an extended bit of time.

Thanks folks!
