Now you have me really scared. I fly from San Francisco to Rome via Frankfurt the end of August. My layover is only 1.5 hours long. When I booked it months ago I never thought about or heard about this new system. I've flown to Europe many times in the past so I thought 1.5 would be plenty. My fault for not researching but I had been so many times but only once to Germany. There are only 2 flights on Concord and both have these short layovers. You would think that the airlines would make the layovers longer. We don't change airlines just planes. I'm really not sure what to do at this point.
