I'll take 14 hrs in QR vs 8 in DL or KLM.
I actually prefer longer flights - I get better sleep in them.
And I will definitely take the DOH lounge over AMS
But my previous experience with QR was onward to JNB -on their brand new Dreamliners...those are very nice.
I can see that their service to JRO/NBO/DAR is on A320's recliners...
