Hi In september we are going aborad for the first time with the baby. Well actually first time with kids. 4 adults, 2 toddlers and a 4 month old. We've booked our flights and reserved our seats (6 plus babe in arms) I'm just wondering what the deal is with pushchairs? Do you need to pre book them with the airline? Do they go in the cabin or hold? are they included or on top of your baggage allowance? I'm looking at getting a second hand lightweight stroller, but my sister is talking about taking the double buggy? Any advice much appreciated.
