One of my clients will only pay for W for any destination and I pay the difference for WT+, however for a short notice trip last week even W on BA was too much for them so I was in CX/KA Y to PVG and back. I was really dreading these flights having not been in LH Y for 6 years or so.

I was however pleasantly surprised that it was more comfortable than I remembered and the service on both CX and KA would cause me to consider their Y again in future. Not much good for sleeping though and having lounge access made a difference too.
