Flew Qsuites DOH-ORD and was very impressed. QR has noticeably improved not only the hard product but the soft product as well. I don't fly QR all that much, maybe once every 2 years. My previous flights have been OK, nothing special. Years ago QR FAs were stiff and formal, almost unhappy. That has changed. This flight was great, more like F than J---friendly and proactive FAs, quite edible food elegantly served, and the door somehow caused me to sleep much better.
Only thing I hated was the map display, which was constantly interrupted by 'smoking not allowed' and other messages.
