Navigate to the airline's website. The url will usually be the name of the airline (i.e. United, Delta, Hawaiian, Southwest) followed by .com.
Click on "Check Flight Status." If you don't see a "Check Flight Status" link or icon on the homepage, type "flight status" into the website's search box.
Enter the required information. You will be prompted to enter the flight number and/or the departure and arrival cities as well as the date of the flight. You will be re-directed to another screen where you can select the flight and view its status to see if it has arrived on time or if it is delayed or canceled.
