The ticket might show 台北 , but the airport is actually at 桃園.
I found that many passengers from other countries get confused.
Last time a foreigner asked me how to go to the train station, and I had to ask him indeed which train station he meant.
It seems the poor guy had no idea where he is, he thought he was already at Taipei!

Anyway typhoon is close, beware of wind and rain.
May you enjoy your trip!
