Geoff, as above, if overfilled it will leak, but I’ve used mine in all weathers (from Moscow winter to Singapore downpours and all points in between!) Very, very pleased with it.
Ivantate – 120k? About 175 here, I think. Luckily, haven’t flown anywhere since October! Already got Australia, and a few US trips lined up for next year.
an hour or so wait for baggage
Where are you flying? I spend a lot of time doing one night stops around Europe (This year has included Barcelona (lots!), Madrid, Moscow, Frankfurt, Amsterdam, Glasgow, Munich, Paris, Stockholm etc, etc) and my experience is never that! OK, on some long hauls I’ve had long(ish) waits for baggage, but never more than about half an hour! Then again, I do have a nice “priority” tag on my bags, so that might help!
