Should be illegal, Susan.
Frankfurt is a different bracket, I'm sure it's actually possible to have a decent experience there, it's just that if it's anything other than a straightforward in and out job, you're in trouble. Everything is fucking miles away from each other. If you're changing there with any kind of a tightish turnaround then it is a total nightmare.
I also flew back through there (Hamburg-Frankfurt-Birmingham) about three months after 9/11, got stuck going through the same queue to departures as a flight to New York and the security checks were ridiculous, nearly caused me to miss my flight completely.
So should calling me ' Susan ' !
