OK

pu2. It rarely happens when you get on the starting point, and the closer you get to the airport, the less seats you have

OK

pu3. In the case of the first train, it is often full. You have to be careful when you get on the first train because the flight time is fast. I'm in a hurry to schedule the flight, but it's often full
