My return trip started out painfully but ended well enough. I arrived at the Air France counter at the Brussels Midi train station to find that the train I was booked on for Paris-CDG airport was not the Thalys as my colleagues had assured me, but a regular TGV and hence out of service because of the strike. Well. Air France had a bus heading to the airport but it wouldn't arrive in time for my flight. Luckily I was able to get on the later flight to Washington DC.
I went from the land of pink-cheeked Belgians who looked like prosperous medieval burghurs to a plane full of Americans anxious to get home in time for Thanksgiving.
