Overall Frankfurt is okay but not particularly cutting edge. I often fly to the UK from it and hate the fact that you have to go through security twice. For flights to the UK you go through the main security area but then have to go through a smaller security right before the gate. Usually when I am traveling it is with my young son and after hauling all my luggage through security number two to the gate waiting area I have been dismayed to see that the toilet is outside the gate and before security. I then have to haul all my stuff back out of the gate to use the toilet and then go through the security line all over again. What idiot puts toilets outside of the gate and security? At least put a sign warning people there are none in the gate waiting area!
