Flying Frontier Airlines can be a great way to save money, but there are a few key things you need to know before you book your next flight.

We’ve flown budget airlines like Frontier before, and trust us – going in prepared makes all the difference. Here are three important rules to keep in mind before you fly Frontier in 2025.
Budget for Bags and Seat Assignments
Frontier might have some of the cheapest base fares out there, but don’t let that fool you – those low prices don’t include much. If you’re bringing more than a small personal item, you’ll need to pay extra for a carry-on or checked bag. And those fees can add up FAST.

Seat assignments? Yep, that’s extra, too. If you don’t pay for one, you’ll be assigned a seat at random when you check in. If you’re traveling with family or friends and want to sit together, you’ll need to factor in that additional cost.

Pro tip: Pay for bags when you book your flight, because the price goes up the closer you get to departure. If you wait until you’re at the airport, you could be paying way more than you expected.
Be Wary of Long Layovers
Frontier’s ultra-low fares can be tempting, but sometimes they come with, well… conditions like 11-hour layovers. (Yes, really.) When you see a super cheap flight, make sure to check the total travel time before booking.

Budget airlines often offer the lowest prices on flights with long connections, odd departure times, or inconvenient routes. If you’re okay spending half a day in an airport to save a few bucks, go for it! But if you’re on a tight schedule, it might be worth paying a little more for a more convenient itinerary.
Check In Immediately and Have a Backup Plan
Frontier isn’t alone in being known for overselling flights, and if your flight is full, the airline will bump passengers who checked in last. To avoid getting left behind, check in as soon as the window opens – usually 24 hours before departure.

And if you’re flying Frontier to a time-sensitive event (like a wedding, graduation, or Disney vacation), you need a Plan B. Budget airlines don’t have as many daily flights as major carriers, so if yours gets delayed or canceled, you could be stuck. Before you leave, consider having a refundable backup flight booked or a rental car reservation on standby. You’ll thank yourself later.

Flying Frontier can be a great way to travel on a budget, but you have to know what you’re signing up for. Extra fees, long layovers, and overbooked flights can catch travelers off guard if they’re not prepared. But if you budget accordingly, check your itinerary carefully, and plan ahead, you can make the most of your Frontier experience without any major headaches.
