OS is a little better than LH old C definitely better than TG old C. Seats recline quite a bit. Very much on par with SK, but better service on the food. Better amenity kit, very small C cabin (24-34 seats). No Y+, upgrade policy just like LH. (op-ups only on overbooking, M&M status memebrs get first preference), no upgrade for cash unless you want to pay the C fare difference.

BTW, this question belongs into the *A forum, where it was already discussed...
