Heads-up: I'm heading across the pond

I’m heading over to the UK for a week, starting this Wednesday. I’ll be flying from SEA to LHR via ORD, getting in around 6am on Thursday. From Thursday through Saturday I’m going to be staying in Oxford, visiting my mother and brother (and hanging out in the city). Then on Sunday I’ll take a train in to Paddington, tube to King’s Cross, and a GNER train to Edinburgh. Amazingly, this is only my second visit to Scotland. (The first was a day trip in about 1975, when I was a post-grad student at Newcastle-on-Tyne.) On Monday and Tuesday I’ll be at Amazon.com‘s Edinburgh Development Centre for a variety of meetings. (Long-time readers will know that I’ve always been interested in the challenges posed by distributed development.) And I’ll fly home on Wednesday: BMI from EDI to LHR, then United LHR-ORD-SEA.
Now I just have to work out the crazy (and constantly changing) rules for carry-on bags on flights to and from the UK….
(It would be great to pop down to see some of my old mates from SunUK, but I don’t think the schedule will allow it. Plus I’m going carless on this one; I’ll be taking the bus from Heathrow to Oxford. Maybe next time.)
