One last thing for anyone flying with car seats...we learned on our last flight over here that car seats are rated in terms of where they can be used. One of our seats was FAA approved...the other was not. So we had to gate check one of them. We had never had an issues before so it might be a "flying overseas" thing.
That's car seat hell for you. Well before our flight last year, I called Delta 5 times to enquire about specific car set requirements. No one was able to tell me with any certainty if the English car seat I had would be accepted on the flight.
A rep at Delta's London office told me the car seat had to be FAA approved. When I asked her how foreign travellers with small infants managed to fly Delta without FAA approved seats, the only thing she could do was direct me to contact the TSA. So Delta takes money from non-Americans daily, but their standard, inflexible criteria only seems to cover Americans.
I ended up paying a visit to Gatwick twice to speak to a Delta rep in person. An employee found Delta literature pertaining to non-American car seats. English car seats are stamped with an EU number and symbol, an equivalent to the FAA. The English employees had a difficult time finding the information, and I was sure a flight attendant in the US would stop me from using the eat after not recognizing the EU symbol's significance.
Luckily, I decided on a slender Britax model and I was able to use it during the entire trip without hassle.
Overall the lack of information caused me a tremendous amount of stress and aggro, and over information (I still feel) should have been straight forward and easy to obtain.
Grrrr.
