The airline with the best average grade is Qatar Airways with 8.7/10.
The average flight time is 7 hours and 40 minutes.
The A-350 is a terrific airplane. I had a very comfotable flight in a very quiet environment. Engines are very quiet , I was amazed by this. Temperature was a bit warm during the flight but that was well managed by the crew. Food on this sector was average, cleary a Singapore catering issue but the wines were excellent as the wine list is the same in Business for all the network of Qatar Airways.
I have become a big fan of this company that delivers a fantastic quality/price ratio that unfortunately legacy airlines are falling behind but for sure that is another topic that we won't cover here.
Thanks for reading and safe travels!
