I'm looking at booking a holiday with TUI. I've just discovered their free child places are for children aged 2 years+. So to take my son at 21 months it's over £400 more expensive (than a 2 year old) cause he's classed as a 1 year old, even though he doesn't get a seat or baggage allowance and a 2 year old does 🤯 My question is, if I put my son down as 2 years old, will the airline question it? And if they do, what will happen?
