I have flown AY HEL-LAX on AY1 and HEL-HKG on AY101, shortly to fly BKK-HEL on AY. Overall I have always been impressed with them and would certainly class the A350 as a desirable aircraft to fly on. I actually prefer it to the B787, but I think the sense of space on the A380 is difficult to beat.

If AY works for you and if the TP are similar (and important) I would give AY a shot. Only caveat, all my AY trips recently have been in J.
