Got ready to board. In fact the first two zones were boarding and then discovered a flat tire on the plane. Everyone had to get off. Got ready to board again and then they discovered two blown out lights. Had to special permission from some executive to fly without the lights. Got that. Boarded again. It was bad enough to lose three hours because of the time difference but we were even later. So this meant I was up fifteen hours.

The people from check-in, to the cabin crew, to flight crew were all pleasant and efficient. The under seat space were a little cramped.

Everything was fine, but would have been nice if they offered some coffee and tea. Especially since it was so early in the morning
