We have done an awful lot of traveling with our two under fives and have always taken our buggy as far as the gate - from a Stokke, maclaren, quinny and Jane powertwin - never had a problems. They generally just ask you to fold it before they take it off you as they don't now how to do it themselves and then you pick it up at the other end. Only time we ever had a problem was in Rhodes when they put our Stokke on the conveyor with all the other luggage and it of course didn't fit and broke, but the insurance paid out when we came back so wasn't too bad! Congratulations and good luck.
