Is it enough to transfer from San Francisco to Denver airport for one and a half hours?

If it is made in China, it is enough.

It's a little tight to come in from abroad.

If you miss your flight, of course, you should find the next airline, explain the reason and see if you change it for free or for a fee. When all international flights arrive in San Francisco, passengers must get off the plane and enter the country. The only way is to go to the immigration office-check passports, visas and other documents. Immediately after the immigration office, I said the baggage carousel, took out my baggage and went through the customs to check the substance with the immigration declaration form issued by the ship. Go through the customs and pay attention to the baggage transfer sign (baggage consignment). If you have hung your luggage directly to Denver in China, and there is a note from Denver on your luggage, you don't have to go through any formalities, just push it over. Pay attention to the screen to see where the boarding gate of Denver is, leave the terminal, take a free car ferry or walk. Go through the security check and go to the boarding gate. If you miss your flight, find the airline counter and tell them the situation. Whether it is reasonable (such as delayed flights, delayed entry procedures, etc.). ), maybe you can change your visa for free. Go to the official website flysfo airport to check their maps or interactive maps.
