Also, just a reminder. In Great Britain it's one carry-on period. Fortunately, we had put all toilet articles in our checked luggage, so we were able to get the camera case in my carry-on and Lynn's purse in hers. There are also other differences from the States in that you can't bring any sharp object( like short scissors) and no lighters. And, Gatwick is as bad, or worse than Heathrow.
