I've flown a few times with my DS classed as an infant and had no trouble taking car seats, buggies etc. with me as there is usually and allowance for 'infant' equipment. However, I'm about to book a (low cost, short haul) flight for just after his second birthday and there doesn't seem to be any allowance for car seats and buggies as he just gets the same as any adult (approx 10kgs hand luggage depending on airline). I am really going to need a car seat and a buggy while I'm away, and preferably a travel cot too. Any advice on how to take these would be greatly appreciated!
