Train Peterborough to KX, then a quick walk to St. P Intl and down the old Thameslink (now FCC) service to Gatwick - arrived about 10:30. As I'd checked in and printed my boarding pass online, and had no need of bag drop, went straight through passport control and security in nothing flat with no hassle. Definitely worth doing THAT again.
Grabbed a cooked breakfast at the Wetherspoons'. Milled around a bit and failed to find a decent and non-pricy pair of noise-cancelling headphones at Dixons, so settled for Marcus Trescothick's autobiography and the latest Scarpetta in a 2 for 20 deal from Borders, and headed for Gate 17.
Not that crowded a flight, boarded on time, (name withheld) was just behind me in the exit row gap making all the pre-flight announcements and being generally friendly. The folks in 48 A/B were angling for exit row, and there was a bit of pre-take-off negotiation with her which resulted in them getting seats in 25 B/C, some folks from elsewhere getting 49 A/B/C and me getting 48 A/B/C all to myself, which was just fine, thanks

Took off on time, in general a nice smooth flight. The folks in front were mostly happy to sit upright, so I got to spend some time with the smaller netbook writing my talk (and revelling in the 8 hours+ battery life). Watched 'Clone Wars' and the superb 'Man on Wire' on the less-than-stellar Nova system (didn't check which plane I was on, sadly).
Staff in general friendly, food decent - the BBQ chicken was remarkably nice, and I'm a sucker for G_ mousses. Choc ice mid-flight was still pretty much frozen, though, when it got to me.
Landed almost on time (watching from 48 A), spend the usual age taxying, disembarked at 1710 local, and got entirely the WRONG queue in US Customs - anytime you hear the 'Welcome' bit of the video loop five times, you know you backed a loser. So much so, most of the checked baggage was out by the time I made it through: finally met my ride at 1810.
