Hi,
I am planning an award trip to BKK and have the option of flying the longhaul sector via FRA, ZRH, MUC or CDG.

I am not a regular Thai flyer and would like your view on which flight I should book given the different aircrafts. Obviously interested in the most up to date F product.

From FRA I can choose a 744 flight or a 773.
From MUC is the 744
From ZRH is the 346
From CDG is a 744

Which flight would you recommend?

Thanks for any help.
