Why do airports go to one place twice in a row?

1. Flight transfer: In some flights, passengers may need to transfer at an airport and wait for the next flight to their destination. In this case, the airport may become an intermediate stop for passengers to go to their destination.

2. Flight delay or cancellation: Sometimes, due to weather, mechanical failure or other reasons, flights may be delayed or cancelled. In this case, passengers may have to wait for a while, and then take the same plane or another plane to their destination again.

3. Return to the origin: In some cases, passengers may need to return to the origin immediately after arriving at their destination. This may be due to emergency, misoperation or other reasons. In this case, the airport will become the starting point and destination for passengers to travel back and forth.

4. Airport facilities and services: Some airports offer a wealth of shopping, dining and entertainment facilities, attracting many passengers to visit during the waiting period. In addition, some airports also provide business centers, lounges and other services to facilitate business travelers to handle work or rest.

5. Tourism and sightseeing: There are famous tourist attractions and cultural activities around some airports, which attract many tourists. In this case, the airport may become a transit point for tourists to travel to tourist attractions.
