Frontier Airlines Baggage Fees

I remember the first time I took my toddler on a flight with Frontier Airlines. We had packed everything we thought we'd need—strollers, car seats, baby carriers, toys, snacks, and even a few changes of clothes. But I didn't realize that Frontier Airlines has specific baggage policies that could add up to a surprising cost. As a parent, planning a trip with a young child is already a balancing act, and not accounting for baggage fees could throw the whole trip off course.

Frontier Airlines is known for being a budget airline, but their baggage fees are an important detail that parents like me often overlook. I learned the hard way when I was charged extra for a carry-on and a checked bag, which I hadn't anticipated. It's easy to get caught up in the excitement of a trip with your child, but understanding Frontier Airlines baggage fees is crucial to avoiding unexpected costs that could impact your travel budget.

After that initial experience, I made it my mission to research and understand the baggage policies of Frontier Airlines in depth. I wanted to be prepared for my next trip with my toddler, and I knew that if I didn't plan ahead, it could cost me more than I had expected. What I discovered was a mix of surprises, some of which were helpful and others that required careful planning. Understanding Frontier Airlines baggage fees is a key step in ensuring a smooth and stress-free family trip.^[1]

What Are Frontier Airlines Baggage Fees for Families?

As of September 2026, Frontier Airlines has a clear baggage policy, but for families with toddlers, it can quickly become a source of unexpected costs. I found that carry-on bags are free, but checked bags start at $35 each way. This can be a shock if you're not prepared, especially if you're traveling with a stroller or car seat that may need to be checked as a separate item.^[2]

To manage this, I learned that it's helpful to plan ahead and decide which items can be packed in the carry-on. This means avoiding large, bulky items that can't be brought on the plane. If you're traveling with a stroller or car seat, you can bring these on the plane for free, but they may not be able to be checked as part of your baggage limit.

I ended up checking one bag and bringing a carry-on, which meant an extra $35 fee. I had to make sure I wasn't bringing anything that could be packed in the carry-on, like a blanket or extra diapers. This was a learning curve, but it helped me avoid future surprises.^[3]

How to Navigate Frontier Airlines Baggage Fees with Toddlers

I found that the key to managing Frontier Airlines baggage fees is to use the free items allowed on the plane. This includes a stroller or car seat, which can be brought on board without being counted toward your baggage allowance. I learned this the hard way when I was planning a trip and didn't realize that my stroller could be taken on the plane for free.

I also discovered that I could pack a carry-on and a personal item, which gave me more flexibility. This meant I didn't have to check as many bags, which helped me avoid the $35 fee for each checked bag. I made a list of what I needed to bring and prioritized what could go in the carry-on.^[4]

This experience taught me that planning ahead and understanding the baggage policy can save money and reduce stress. It also helped me avoid the hassle of having to check a stroller or car seat as part of my baggage allowance.

Understanding Frontier Airlines' Free Baggage Allowance

Frontier Airlines allows passengers to bring one carry-on bag and one personal item for free. This is helpful for families, as it allows you to bring a diaper bag and a stroller or car seat. I was surprised to find that my stroller could be brought on board for free, which meant I didn't have to check it as part of my baggage allowance.

I learned that the personal item is typically something small, like a backpack or a purse. It can be useful for storing small items like a phone, wallet, or a small change of clothes. This helped me avoid the need to check an extra bag.

I also found that the free baggage allowance made it easier to manage my carry-on, which meant I didn't have to pay the $35 fee for checking a bag. This was a relief, especially since I was traveling with a toddler and didn't want to deal with unexpected costs.
