Hello! I flying Frontier Airlines Terminal ORD it was surprised in a good way. The terminal was tidy and organized. Check-in was efficient, and TSA was quicker than I anticipated it would be. I didn't have a problem with the minimal food options, as there's just enough to pick up a quick bite before boarding the flight. The terminal is very spacious with lots of seats and charging points, which made the wait go by. The boarding was a bit chaotic (as always with Frontier, but other than that, everything ran smoothly. If you're taking from, you'll have a fairly good experience with no big problems.

Which Terminal Does Frontier Airlines Use at ORD?

Let’s start with the basics: Frontier Airlines operates out of Terminal at Chicago O'Hare. The terminal is primarily used by American Airlines, but Frontier has a dedicated section in Concourse L. It's easy to find, and signs are posted clearly. Terminal the newest terminal at O’Hare, but it’s functional, busy, and full of life. We had no trouble navigating it, even with two kids in tow and a couple of carry-ons.

Check-In Experience: Smooth Sailing (If You’re Prepared)

We arrived about two hours before our flight, which gave us plenty of time to check in, drop off bags, and go through security. Frontier Airlines has self-service kiosks available in Terminal, and using them really speeds things up. We printed our boarding passes, luggage tags, and paid for our bags in advance online (a must-do with Frontier if you want to avoid extra charges). The Frontier staff at the bag drop were efficient and friendly. One team member even helped an elderly couple who were struggling with the kiosk—just a small gesture, but it made the whole environment feel more human and welcoming. A quick tip: if you're new to flying Frontier, know that they charge for carry-ons and checked bags, and even for seat selection. It's budget travel, so everything is a la carte—but if you're organized, it's not a big deal.

Security: Busy but Manageable

Security at O'Hare can be hit or miss. It was pretty busy when we went through TSA, but the lines moved relatively fast—about 25 minutes from start to finish. We had prepped our liquids, electronics, and kids’ snacks ahead of time, which helped. The TSA agents were businesslike but polite, and a staff member guided us to a family-friendly line. Honestly, considering how hectic O’Hare can get, this part of the trip was smoother than expected.

Concourse L: Frontier Home Base

Once we got through security, we headed to Concourse L, where Frontier  gates are located. This area had a decent layout, with plenty of places to sit, plug in devices, and grab a snack. It’s not the most glamorous terminal (like United’s newer sections in Terminal), but it’s clean, bright, and practical. The gate agents were organized and clear with announcements, and there were plenty of people around if you had questions. We loved that there were USB ports and outlets near most seats, especially for keeping tablets charged while the kids played games before boarding.

Dining Options and Amenities

Terminal 5 has a surprisingly good mix of food options—not just fast food but also healthy and family-friendly choices. We grabbed sandwiches and coffee and still had time to relax. The bathrooms were clean, there were hand sanitizing stations everywhere, and signage was posted in multiple languages.

Boarding the Flight

Frontier Airlines uses a zone boarding system, and the gate agents managed it efficiently. They allowed families with small children to board early, which we really appreciated. It made it so much easier to get settled before the rush.  Even though Frontier gets a reputation for delays or disorganization, our flight boarded right on time. The staff were upbeat and made sure the boarding process went smoothly—even helped a few people struggling with oversized carry-ons figure things out without causing drama.

Onboard the Frontier Airlines Flight

The Frontier cabin is plain and no-frills, but if you understand what you're getting into, it's no issue. The seats don't recline, legroom is minimal (we shelled out extra for legroom in the front row), and there is no seat-back entertainment. That being said, the cabin was clean, well-lighted, and fresh-smelling, which is more than I can say for some other carriers! The flight attendants were pleasant and competent. They provided a brief safety demonstration, served drinks and snacks (for sale), and did some light-hearted announcements that really did make people laugh. We brought our own snacks and entertainment, which I would definitely recommend, particularly with children.

Family-Friendly Features

O'Hare is remarkably friendly for families, particularly Terminal 3. They have family bathrooms, an ample supply of elevator rooms for strollers, and even a play space for small kids at Gate K2 if you're inclined to roam around. Frontier did not make us feel treated differently simply because we were traveling in economy class. Actually, a gate agent saw we were trying to balance a car seat and stroller and kindly offered to tag and check the stroller at the gate before we even requested it. Those are the little things that make a difference.
