Shy; one problem lies with the 'can do steps'. Airlines tend not to differentiate between some steps and 1000 steps. If you have a limited amount, do yourself the favor of filling in no steps. You'ld rather have a higher mobility than they reckoned than the other way round.

But more important; the problem with LH and FRA are of such a size even their own staff is complaining about it. I've had large part of the crew, including the pilot, very strongly ask me to please file a complaint as they experience major problems with special needs situations apparently more often than not. Says it all, imho.
