We're looking to fly from Gatwick to Estonia with our 4-month-old daughter next week. The plan is to take the carseat and wheels through security and give them to the airline to put in the cargo hold for the duration of the flight. Unfortunately neither the airline nor the airport can confirm that this is possible. Both say that they think "it should be doable". Therefore I would appreciate comments from people who have flown from Gatwick with their infants. Have you had any problems with security? Have you got any tips on how to make the flight less painful for everyone?
