I've been flying long-haul Qatar in Economy pretty often for the past 6 months. Legroom is reasonable but the seat cushions become uncomfortable within the first 2 hours of flight. Food is tasty but portions and variation small compared to other mideast carriers. Entertainment is limited (again, compared to other mideast carriers). Crew are friendly enough and processes are clear.
