Tips, Help & Resources

Using the interactive airport maps, iFly.com can help you get through, and between the ONT terminals with ease. Here are some things you may want to know that can help you on your journey through the airport:

If you have some time before your flight's departure, be sure to grab a bite or peruse the shops, but be sure to return to the gate before boarding time!
How long is the line? Be sure to know how long you will need to wait at the security checkpoint closest to your gate.
Remember that a great low-cost alternative to parking within the airport facility is to use on off-airport parking lot. They offer lower costs, a bit further away from the terminals. Reserve here.
