People can complain about airlines costing more money than others but the thing a lot of people don't take into account is cost per mile or comfort cost per mile.
If I had to fly to NY from here in UK, I could fly with a US airline at a cost of £440 or about 13p per mile but that would be shitty quality and service, much better for me to pay £600 or 5p per mile and go on Emirates with better service, it's further to travel but it's by far the better option if you value comfort.
Next month is a trip back to Cebu with Singapore Airlines from Dusseldorf at a cost of 2.4p per mile, getting from the UK to Dusseldorf costs 14p per mile on a shitty budget Eurowings flight.
I'm planning a trip to hong kong next april and it looks like my best options are Qatar, Cathay Pacific, and Emirates. I'm leaning towards Qatar because their A350 looks cool and one of the legs of the flight is on a 787. I've only ever flown on Delta, American, United, and US Airways, so I'm expecting a life changing experience.
The A350 is a great plane to fly on, extremely smooth. 787's are different matter though because airlines are squeezing in 9 seats to cabins designed for only 8 however Qatar's 787's are absolutely awful with a miserable 17 inch wide seat and an IFE box that takes up 1/3 of your legroom.
Oh and if you do pick Qatar, don't choose a short layover just in case you have to wait to be bussed to the terminal from the plane landing.
