I’ve just bought a Joie pact flex signature and it came with a carry bag. I’m going away in December and DS will be 2. My thinking is I’ll use the stroller through the airport, take it up to the plane, fold it down and put it in the bag then put it in the over head storage. We are flying with easy jet. I know the dimensions of the stroller folded down are the right side to be able to do this but will easy jet allow this?
