Helsinki-Vantaa airport, 16:45
I finished teaching the XML Foundations course, ate a sandwich, and headed for the airport. I am spending five days in London researching and having meetings. I am boarding in the plane in a very cold wind.
I am flying Norwegian which is slightly cheaper than Finnair and has the advantage of landing in Gatwick not Heathrow. Today this will not be as much of an advantage because only one runway has been cleared of snow and take-off will be delayed.
