That's bizarre. Ring the agency and ask? Makes no sense to do the coach in that instance. However, I would be collecting her from the airport. I always do for first arrival and final departure. Any trips home in between they have to take the train, tube and coach to get them to the airport!
We will definitely meet her at the airport if we possibly can. She is older (27) but may not have had much experience travelling abroad. This will limit the days when she can travel, though, as we can't get off work, so if she can't get a flight on one of those days we may need her to come at least part of the way by public transport.
I always used to offer to meet my au-pairs at Birmingham Airport. However, this airport mainly deals in scheduled airlines which are expensive and, as au-pairs are responsible for their own airfare, every one of them used to prefer to get a cheap bucket flight to Stansted.
That was fine - but I can't make a 6 hour round trip to Stanstead when I've got 3 children in school.
My argument was, I was happy to collect au-pairs from my nearest airport, a 50 minute drive away, but if they prefer to buy a much cheaper flight to Stansted, they had to be responsible for getting themselves to my town. I thought this is reasonable. How far away is your nearest airport.
I've emailed the agency to explain about the trains and ask if it's ok to arrange it by train - he's probably thinking 'you daft so-and-so, of course it's ok' but then, it does actually say in the terms and conditions it has to be coach!
Our nearest airports (Humberside, Doncaster) would only be reachable from Hungary by a very roundabout and very expensive route, so I don't have a problem with meeting them at an airport a couple of hours drive away - it's just that we are v limited as to when we can actually get there. If she wants to fly to Luton she'll have to get a coach, though.
