Wow things must have changed, as all this wasn't happening last July. Flew Continental and paid everything US-side; asked repeateadly if there would be more to pay on the UK end as I didn't want any surprises -- everyone kept saying no, and sure enough nothing to pay at Gatwick when I picked up my cat. Be warned that was July 2008, so it looks like things have changed -- wasn't like this just a year ago, at least on Continental to Gatwick ARC.
