Can you get from Terminal 3 to Terminal 5 at O'Hare without security?

Navigating OHare International Airport (ORD) can be confusing, especially during a tight connection. Whether you can stay behind security depends on your transfer method and the time of day. Heres how to travel between Terminal 3 and Terminal 5 as efficiently as possible.

Using the Terminal Transfer Bus (Airside)

Yes, you can transfer between Terminal 3 and Terminal 5 without re-clearing security, but only if you use the designated ORD terminal transfer bus. This service operates on the airside, meaning you remain within the secure perimeter. Its a lifesaver for connecting passengers who meet specific requirements. You need a same-day departing boarding pass for a flight from the terminal you are transferring to. Without that pass, you wont be permitted to board the bus. Its that simple.

The bus operates daily from 11:30 a.m. to 9:30 p.m. In Terminal 3, you can find the bus stops near Gates G17 and K20. Once you arrive at Terminal 5, the bus drops passengers off at Gate M13. Keep in mind that these hours are strictly enforced. If your connection falls outside this window, you must look for an alternative route.

The Airport Transit System (Landside)

If you arrive after the bus stops running at 9:30 p.m., or if you dont have a qualifying boarding pass, you have to use the Airport Transit System (ATS) train. Unlike the bus, this train runs entirely landside, which is outside the secure area. Youll need to exit the secure terminal area in Terminal 3, follow signs for the ATS, and ride the train to Terminal 5. Because youve left the secure zone, you will be required to go through the TSA security checkpoint again at Terminal 5.

This process takes significantly longer, especially during peak travel hours when connecting flights ORD Terminal 3 to 5 may be impacted by security lines stretching across the terminal. The O'Hare Terminal Transfer Bus hours are crucial to check, as the ATS operates 24/7, ^[2] making it a reliable backup, but its rarely the preferred choice for a quick connection. Always factor in potential security wait times when planning your itinerary.

Lan's Tight Connection at ORD

Lan, a traveler flying from a domestic connection in T3 to an international flight in T5, landed at 7:00 p.m. with only a two-hour window. She was worried about missing her flight.

She initially tried to find the train, but the signage was confusing, and she almost walked out to the parking garage. The frustration of carrying heavy luggage through crowds was wearing her down.

She eventually spotted an airport employee who pointed her toward the T3 bus stop at Gate K20. The bus ride was short and efficient, keeping her within the terminal.

She made it to Gate M13 with 45 minutes to spare. If she had used the train, she would have missed her connection due to the long security line at T5 that evening.
