I went there (check routing page) and it does show an alphabet character after the 777, but does anyone knows what for example (777) N, P or L means?
How do you know it's a triple 7 with qsuite installed? Because of the plane reg nr vs the info from the first post/topic starter?

If everything stays as it is, 'm gonna fly q-suite AMS-DOH/QR274 on the 26th next week. I have booked my J ticket a week ago and until now, I checked expertflyer everyday and it keeps showing a seat map with q-suite...but i did found out QR still schedules the old biz config on average 1-3 days a week.

I have flown with SQ a350 biz class which seems to look a lot like the q-suite. Can I expect the same experience with QR compared to SQ?[/QUOTE]
