But my top vote goes to Euro 'Business Class' that I experienced recently for the first time as I found cheap 'open jaw' J fares from MNL to Europe/UK.
Very poor standard, cold meal but no better than sitting in economy. Shadow next to me a slight bonus.
For every other intraEuropean journey I use very comfortable rail with a Global first class Eurailpass. Largely works extremely well, even though DB in Germany run late on some trips, though not badly on trains on which I've travelled. Way superior to the European airport and "J" class experience.
