AY has huge problems with A350 routes. Yesterday PEK was switched to A333 while OH-LWB stayed in HEL and LWC went to BKK. LWC had today a 7 hour turnaround in BKK and is expected to arrive 4,5hours late to HEL.
LWC has most likely some problems to be fixed because AY cancelled PEK today, when they could have taken LWC there with ~3hour delay.
Tomorrow LWA will switch JFK to BKK, so again ~1600 miles more to be flown by A350 every day. Let's see how that goes...
