Many thanks for this heads-up.
I was actually looking into our first proper family holiday in several years and eyeing DPS.
Ended up fixing departure date to 22nd to snag PEY on the A35K.
Of course, this will likely make Y on the return on a crowded 777 feel worse...
Always happy to help, enjoy the A350! Yeah, it's a shame that the regional 777s are such a step down from pretty much all of Cathay's other products but I guess it will be phased out in the not-too-distant future, and then all CX aircraft will be up to standard.
