All the flights that we have searched for leaving from Scotland all go through one of the northern cities (Chicago, Newark, Detroit, Minneapolis, etc). This is no good, since we have no idea what the weather could be. This only left us the option of leaving through Manchester, and flying with Delta through Atlanta. But Delta is difficult to work with as far as letting you set up the booking yourself, at least that's the attitude I received, and we are being forced to use an agent. It's costing us as much to ship them back as it did to bring them here. They are also going to have to stay overnight in Atlanta, before being onwards to our final destination in Louisville...all due to the stupid requirements they have, which basically means we have to have 6hrs between arrival and departing on the next flight. That isn't possible, so that's means we have to use the agent so they can board the cats the next day.
All in all, I've been pretty frustrated by this.
