When you know the methods for checking in at the airport, travel becomes more manageable, smoother, and more seamless. In general, you can check in online, use your airline’s app, go to the kiosk at the airport, or avail yourself of the traditional counter check-in method. This article provides detailed ONT Airport check-in information to help you navigate your airport journey more easily and conveniently. So let us get started.
At the Ontario International Airport, there are several ways to check in, as outlined below. Make sure you choose the option that is most convenient for you. When you do not invest too much time in check-in, you may have the privilege of experiencing a shorter wait time at the security checkpoints.
That is the easiest and the best way. When you check in online, you get your mobile boarding pass in advance. This way, you may skip the long lines at the check-in counter and even experience lesser wait times at the security checkpoints. Most airlines open their check-in window 24 hours before the flight’s departure time. It would help to check with the airlines at ONT Airport by visiting their official website or checking their mobile app. Each carrier has its own rules and may differ from others in the online check-in window.
Your next option is to use the check-in kiosks at the Ontario International Airport, available at both Terminals 2 and 4. When at the check-in kiosks, you can also print your boarding pass, if you don’t have one already, alongside your baggage tags. If you have already checked in online and have no checked baggage, you can proceed directly to security.
If you’re not familiar with checking in at self-service kiosks, the procedure is outlined below.
If you wish to enrol in the CLEAR or TSA PreCheck program for expedited security screening, you can find them at Terminals 2 and 4. At Terminal 2, the CLEAR lanes are open between 6 in the morning and 5 in the evening. If you are in Terminal 4, the lanes function from 6:00 am to 7:00 pm.
You may not be comfortable with checking in online. You may require additional assistance with check-in, have large bags, or have special requests. In such cases, you may go to the check-in counters, validate your documents, and check your bags. Most check-in counters open 2-3 hours before departure, while international flights open 3-4 hours earlier.
