A very general observation. It is more helpful if you identify the date that you researched.

I was very impressed when I walked into the cabin, it looks beautiful & after looking around my seat, there was definitely a lot of attention to detail to make the seats more comfortable and passenger friendly. However after spending some time in the cabin & my seat, I began to notice how tight and small the space was in general - both the cabin & the seat area.
I guess it's because of all the panels and doors of the suite, which takes up quite a bit of space.

The galley area looks tight, so it must be hard for the cabin crew to prepare the meals & drinks etc.
The worst seat has to be 1 E/F which is immediately outside the lav so best to avoid that at all cost.

I was told that the 77W Qsuites cabin is slightly larger than the A351 so that might be a better option. I've yet to try that but I'll be on the DOH-LAX flight later this month so it would be interesting to compare the feeling of space in the 77L vs. the A351

Finally, I won't be picking a rear facing seat in the future, I got a little bit nauseous & uncomfortable during take off & during the flight, it just felt weird to be sitting facing in the "wrong" direction. Had to constantly remind myself that it's no big deal, even when I was sleeping.
The landing was fine, especially since I didn't miss the usual "jerking forward" motion so that was the best part.

Overall an awesome experience on an awesome aircraft. If only all my long haul flights could be on a Qsuite :D

Where would you sit if travelling with significant other on Qsuites?

On our first qsuite leg we are doing the center two seats for the double bed. On our second 4hr qsuite leg I am debating if it's worth trying out the rear facing window seats.

Are they better?

A7-AMJ (A350-900) has been delivered with Q Suite.

HA!! It's not the fact that the seats face the rear, it's everything else in BA J.

A7-ANH (A350-1000 #8 ) has been delivered with Q Suite.

Funny!

Personally, I get car-sick easily, and can't ride in the back seat of a car without getting terribly nauseous and uncomfortable, or anywhere on a bus where I can't see forward out the window, or sitting backwards on a train. On airplanes, I get that way during taxi, but not in flight. I'm surprised @kaffir76 had a problem during flight, but I'm sure everyone's sensitivity is different.

I just flew qr830 to bkk on April 30 and it was actually a qsuite

Me too! Ever since I was a kid, I'd get car sick during road trips & even once, on an airplane on the way to Hawaii when I was 8 yo.
I'd never take the rear facing seats on a train either, or if I had to, I'd position myself sideways or something so that the backward motion wouldn't affect me too much.

It wasn't a problem per se once airborne, though I'd constantly remind myself that I'll be fine etc. (once I fell asleep, I didn't feel anything & I slept for quite a while - such is the beauty of the QSuites seat) :D

Anyway, I've chosen the forward facing seats for next week to LAX - so let's see how that goes.

I flew on that last Friday, it still smelt very new!

I have a segment booked on an A351 Q-Suites as a sole traveller with a choice of 9A or 11K for window seats. Would anyone recommend choosing one over the other?
