That nice peteyoung worked his mysterious magic once more and I was moved from seat 31D to 15F, very nice indeed.
I still can't cope with take-offs and landings, it seems. But for as long as the plane was stationary on the ground, or in motion a respectable distance above it, I had a good journey.
And the last piece of email I received before going offline for the flight at 10:26 UK time was a piece entitled "FW: foot long sub". I am assured that this refers to something satisfying with a meat filling, but I suspect I'd do better with some sort of baguette.
