I saw this in Stockholm in February or March and I thought it was a Swedish thing because it was so awful. Designed to make people suffer. Took pictures and sent it to friends. Avoid KLM.

Those sitting from rows 15 and back where forced to board through the rear door, so they had to to go down a stairway into the tarmac, walk to the back of the plane, and then climb the stairs to the rear door. It was -7 degrees outside and very windy (17 knots). The last passengers also got to taste some snow.

Never been so happy to be sitting on the front, but maybe that is what KLM wants, make it a lot worse for those sitting on the back so that more will buy comfort seats. I really can't believe forcing passengers to take a longer and more difficult way to get to the plane will save time.
