You make it sound as if you've had enough of flying the Premium cabins and want to try something different...no problem with that it's just not very common here on FT
Not sure I've had enough of it, would happily fly premium for economy prices
.
Thankfully cheap business class returns seem to crop up fairly often for trips I know I need and can plan months in advance (did EU-Asia return for ~$1300 earlier this year and have EU-South Africa booked for not much more next year). The big change is much less travel for the sake of travel or EQD/EQMs.
