So the functionality of the case is an absolute hit. When flying with children there nichst better for hand luggage. My son loves the suitcase. Long distances in the terminal must be set back are also not a problem if you have no more strollers there. Simple child on it and drag. Works well and is fun. Waiting times also not a problem because the case always has a sitting area. The only restriction: it does not fit a lot in. Therefore, even for hand luggage (toys, Paint, etc.).
