Not 100% true unfortunately. Although I do agree that they won't put a 6 year old alone on the flight, my daughter went to New Zealand last summer to stay with her BF's family, she was 15 and he was 18. They flew with BA to Hong Kong and then Cathay Pacific to NZ and they were seated seperately. Now I know a 15 year old is not very young, but she was still a schoolgirl and therefore still a child. I had only agreed to the trip as I was taking them to the airport and they were being picked up by his family and he was a very responsible 18 year old. I felt pretty confident that she would be safe on the plane with her BF. She was extremely upset as she is not a very good flyer and for such a long flight she was terrified to be on her own and to make matters worse, it was her BF's birthday on the day of the flight and she had organised a little suprise b/day cake for him etc to bring out once airborne.
Both her and her BF tried everything to get the staff to re-arrange the seats but they wouldn't, I ended up going back to the airport to try to sort it out, but still they wouldn't oblige. I almost told them to pull off her luggage, but she desperately wanted to go.
Quite a way into the flight, my daughter asked other passengers if they would swap seats and eventually they found a lady traveller who agreed. So obviously it could have been done in the first place and would have saved a lot of heartache.
But with all that said, OP I'm pretty sure that they cannot expect a 6 year old to be seated without one of the adults.
sorry to hear this. Was it the UK airline that separated them too?, because this is against the aviaition authority guidelines which all do follow. It maybe that the 'child' age (in relation to pricing etc.. is perhaps technically classed as 12 maybe? Anyway, either way I am suprised BA did this?
Hope it doesn't happen to anyone else - and if it does I advise anyone to really make a fuss at check in
