When they announced the full flats on the HKG route, I decided to check how Finnair J compares against CX business class and made a mistake of booking a AY long haul ex HEL for my summer holiday in June.

This promise for full flat is the usual Finnair "promise". I took a flight on 5th of June to HKG and that route was promised to have full flat. When I entered the cabin I noticed that it was the old torture J instead. I spent the entire flight thinking that I could have taken the Cathay instead. Naturally my comparison ended with CX 6 - AY 1. Only the wine list was marginally better in AY.

I would treat this promise of full flat on "promised" routes with great caution. Play safe, take CX. After, its the best business in OW.
