Actually I have now used QR three times, all using the new airport. Everything has been 100% fine. Lots of helpful staff on the ground. Maybe I am lucky, and most of the issues at that airport have been resolved. I do like the on board experience, I did love a new 787 Plane, the staff were fabulous and faultless and I slept five hours which is a record for me. As Havoc10G says, it is a different experience onboard, and I have had so many fabulous EK crews, but I think I prefer the QR experience. Both fantastic, but I prefer the on-board QR approach. And my bags arrive. This is a deal breaker for me.
Maybe the rose colored glasses will come off at some point, but so far I feel like Qatar is like emirates of few years ago, when nothing ever went wrong, but when it did, you felt like you had communicated with someone who cared. Maybe I need for something to go wrong at QR and see how they really compare.
