Asiana Airlines is an airline company that is based in South Korea. It mainly operates flights to the ORD from its home country.
Upon arrival the ORD, passengers of Asiana should expect to find themselves at Terminal 5, which is deemed the international terminal. However, this is not a set rule, and the flights of Asiana may actually arrive at any terminal, especially Terminal 1. This is particularly the case for flights that are codeshare flights being operated by other airlines.
If your Asiana flight is leaving from the ORD, then, as is the case with the arriving flights, you could find the check-in desks and the designated gates at just about any terminal. However, more logically, the flight is most likely set to depart from the terminal that handles international flights, which is Terminal 5. If not from Terminal 5, especially if the flight is a codeshare flight, then expect it to depart from Terminal 1.
With the concept of codeshare flights causing some uncertainty, it is a great idea to check the details of your Asiana flight ahead of time.
