Frankfurt Airport

large and well connected airport globally but signage is quite poor for connecting or transiting traveller, especially if you are from one of the remote stand. Staff can be hit or miss when trying to ask for help but they are all quite polite. Also boarding at the gate can be quite crowded due to heavy passenger volume and traffic as well as small terminal spaces. Also the security section is not demarcated well, if you aren't careful you might accidentally leave the security section and have to go through security again, not great for transferring passenger.
