Ah, is that the problem? I must have read about it in another airlines' forum and confused the two?

She is using the Skyflyers service, at least I hope so, as the information had disappeared from the original request and I had to go through it all again today. The main reasons I want to accompany her aren't critical. a) I know how dozy she can be, when she first started using buses on her own to and from school, she often called me from strange places to talk her back home and b) she apparently can't enter a lounge without an adult. But if she's ever going to do this confidently in the future (and I very much want her to), I'd like to have her take the lead this time, knowing I'm behind her to help.

I've never travelled through BOS before, I do feel more comfortable sending her on her own if it's an easy airport. I'm sure she could handle DFW and SAN on her own, but not LHR or LAX.

Thanks for your responses.
