Same old problem, nobody knows anything when you like to use your extra allowance on seldomly used partner airlines, same when it comes to upgrades renting cars, checking in at hotels.I will never forget the expression on the face of the Golden Tulip Manager after showing him the FD book and he realised that every FD Blue Plus member is entitled to an upgrade..

By the way, I am not really sure that the extra baggage allowance is applicable on Comair...
And to be honest, it is a lot to ask for, if the Comair Supervisor has nothing about it in her documents.Good to read that it worker out.

Always tough to find out who did not update his employees correctly, knowing KLM, I tend to believe that KLM is responsible...

Under any circumstance one should always carry a FD rulebook or a more actual printout from the website.
