The plane at 9:00 arrives at Taoyuan Airport at 11:00, and then goes to Songshan Airport to transfer to the plane at 14:40 or 14:30 to Kinmen. How can I get there?

There is a direct MRT train from Taoyuan Airport to Taipei Main Station, and only 2 or 3 stops. Run for 40+ minutes, then get out of the station and look for MRT Bannan Line to Zhongxiao Fuxing Station, then transfer to Wenhu Line to Songshan Airport Station. After exiting the airport customs, the whole journey is MRT, but the airport line is separated from other lines in the city, even if you hold an Easy Card, you have to go to the station and then enter the station. In addition, the customs queue at Taoyuan Airport is very long. I have arrived at Taoyuan Airport 3 times at noon and evening, and the longest queue was nearly an hour. Such a turnaround should come in time. Personally, I estimate that the entire journey will take 1.5~2 hours after customs clearance. You must find a map to familiarize yourself with the situation of Taoyuan Airport before departure. You can log on to the website of Taoyuan Airport. There are two types of vehicles on the MRT line from Taoyuan Airport to Taipei Main Station. You must take a direct train (Slow station stop). Taipei Main Station is also very complicated. It takes 10 minutes to get out of the airport MRT station to the MRT Bannan Line platform, and the next transfer is much more convenient. I wish you the best of luck.

It takes 650 meters to walk from the airport to the blue line and Bannan line. It is very hard to drag the luggage. It is also quite far from the underground to the elevated line when the blue line turns to the brown line. The two transfers will cost a lot of money. If you have less time, it is recommended to take the 1840 bus. One bus goes directly to Songshan Airport. There is one bus every 25 minutes. The journey time is 50 to 60 minutes. The fare is 140 cheaper than taking the airport MRT. This is the most convenient choice. The timetable is shown in the attached picture

Rapid transfer to high-speed rail, faster than cars.
