1. The so-called United Airlines has a system to reduce costs. There are many systems in Taiwan Province Province. If you run for a long time and a short distance, you will find that you obviously bought an EVA air ticket, but the plane you made was China Airlines. This is the way they invented to cut costs. The two companies run the same route, and passengers who can't digest other flights can be put on other flights with fewer people by cross-flight. Everyone can make money and meet the minimum needs so as not to lose money. If you want to transfer after you get the ticket, it's up to you. For example, if you want to fly to Brisbane, Australia, but you want to transfer in China Mainland and Hong Kong, then your ticket will be written as 2006/09/18/Taipei to Hong Kong, which is September18 at 4: 00 p.m. Taipei flies to China Mainland and Hong Kong 2006/09/182. If it's the next day, you have to spend the night. If not, it depends on when you take off and report to the empty bridge on time. Otherwise, ask the airline if it needs to stay overnight. Basically, they provide hotels or not. However, according to your first question, I know that your two flights belong to the same airline, otherwise there will be no saying that you can't take a connecting flight, so you should even have a hotel for the night and re-enter the customs. You don't even have to get off the plane when you leave the customs, only for those who want to get off. I have taken these four flights and took off immediately after landing. I mainly look at how to write the ticket. Ask the airline before you leave. The time on the other ticket shows the local time. Oh, remember. Don't make mistakes. The daily flights are fixed. In some remote areas, there is only one flight a day. Once you miss it, you have to wait for the next flight, so it depends on whether you can catch another flight when you land.
