ur2,
That is exactly right. Trains, buses and now planes wait for no one. If you're late, they'll just leave without you.
Having been in aviation for over a decade, it still astounds me how people are so arrogant to think that an airline will delay a plane full of people in order to wait for one latecomer.
It is no secret that passengers must get to the airport in plenty of time for their flight. Now it's just being enforced.
