I'm in Stockholm airport, waiting for a flight to England. The flight is delayed by half an hour, which gives me 20 minutes from touchdown to get to the bus station, not very likely in Heathrow. If I miss the last bus, I can take the last tube to KX, and that gives me 6 minutes to get up from the underground station into the mainline station and catch the last train to Cambridge. If I miss that, I'm stranded in Kings Cross, which seems worse than being stranded in Heathrow! So most likely I will end up hanging around Heathrow for 4 hours, getting into Cambridge some time after 6 am. That sucks very badly, and it's exactly what happened a year ago; it's almost enough to make me want to go back to Ryanair.
Oh well, even if tonight is hellish, I will end up in England where I'll get to see cartesiandaemon and my parents and maybe some sibs and any other friends I manage to catch between Xmas and New Year. And in the middle I'll go to cartesiandaemon's family in NW England for my first real Christmas. And celebrate my 30th birthday.
