we are planning to take a 4 month old on a flight from gatwick to almeria in april flying with easyjet. my question is where do we stand with a carseat? he is to young to use a pushchair which is allowed on flight but we do have a quinny travel system where the car seat fits to the wheel base and would like to use this. would the carseat have to be checked into hold and therefore would it be taken out of luggage allowance or could we take on board? has anyone had any experience of this?
