ONT Airport Overview

To help you plan your layover or overnight sleepover, here is a quick run-down about what to expect during your time at Ontario International Airport.

What to Expect

Ontario Airport (code: ONT) has three terminals: Terminal 2, Terminal 4, and an International Arrivals Terminal. All flights depart from Terminals 2 or 4, while the two-gate International Arrivals Terminal is dedicated to flights arriving from international destinations. An Inter-Terminal Shuttle connects the terminals on the landside. Amenities are limited to a handful of eateries and shops in Terminals 2 and 4, plus free WiFi.

Security & Safety

Sleeping in any airport can include a certain level of risk, especially when travelling alone. It’s important to take certain precautions to ensure your safety and the security of your valuables. Here are a few tips:

Safety First. It’s a good idea to know where the security office is located and look for video cameras where you plan to sleep. You can also ask the security personnel for advice on the safest places to spend the night.
Don’t Seclude Yourself. If you’re travelling alone, we recommend you stay near other travellers or close to security. This will help you feel more secure and deter potential thieves.
Hide Your Valuables. It’s also important to hide your valuables. Don’t leave them out in plain view, as this could make you a target for theft. Additionally, if you are a deep sleeper, you may want to padlock your bag to something or sleep with your bag up against a wall to make it harder for someone to access zippers and pockets. We have received reports of sleepers who woke up without their phones and laptop bags. The travellers were left with just their headphones and laptop bag strap.
Stay Alert. It’s best to stay alert and awake if you feel unsafe or uncomfortable. Drink coffee or other caffeinated beverages to help you stay awake, and remember that you can always catch up on sleep during your flight. These simple precautions can help you enjoy a safe night at the airport.
