Thanks both. Feeling reassured (a little anyway). Really I won't feel relaxed until I've collected him again at the other end.
He's used to his crate, it's roughly the same size as his usual one anyway, but he's been spending some time in the travel one over the last week or so.
The airline says he has to be there 3 hours before the flight, we have to be there 2 hours (and given the crazily slow security at Manchester, 2 hours really is the minimum). I wish he could be out and about closer to departure but at least the flight is relatively short at 4 hours.
Definitely no sedatives! That'd only add an extra layer of stress to the whole ordeal.
I have a big plastic clamp-on bowl, so if they don't top up water before he gets on the plane, I'll definitely attach that so I know if we're delayed in the heat he should have some water left.
I'm glad I've only got to worry about this in the one direction since he'll be staying there (but then I have to worry about saying goodbye....). EEEEK!
