Why did my flight take off an hour late - almost missed my connecting flight in Taipei - had to run across the airport there and made my flight by about 6 minutes. Too much stress to start a vacation with. The on-board entertainment system was surprisingly good and the food also quite good. Still, except for going home, I don’t think I will take a 14 hour light again.
