Online check-in is a win
I checked in the flight from Heathrow to Narita this morning and found a seat 1) which is on aisle and 2) seats next to the seat were all vacant.
Actually when I’m on board and found that I’m the only one on the row. I enjoyed the movie Mission Impossilbe III and ALWAYS (the Japanese one), then slept away taking those three seats as flat. So good.
