boarding process was smooth, Crew was excellent. i booked Comfort+ the seat was good but very old and the entertainment screen get stuck and difficult to control again maybe because its old device brought from other old airplanes not belong to Qatar Airways new fleets. Food is not at all matching the hype of Qatarairways, what i had in Emirates or Etihad economy class is way better.
