Understanding Frontier Airlines Baggage Policies

Frontier Airlines operates one of the most restrictive baggage policies among U.S. carriers. Unlike many competitors that include checked bags with most ticket types, Frontier charges separately for nearly everything beyond a personal item. This guide explains what those charges are and how they work.

As of 2024, Frontier's basic "Basic" fare includes only one personal item at no charge. A personal item is defined as a purse, laptop bag, backpack, or similar small bag that fits under the seat in front of you. Anything larger—including a standard carry-on roller bag—requires payment.

The airline's fee structure includes carry-on bags, checked bags, seat selection, and beverage service. Understanding these charges before booking helps you make informed decisions about which airline to use and what fare level might work for your trip. Frontier's unbundled model means you only pay for services you actually use, which can result in lower base fares but higher total costs if you need multiple services.

Frontier's business model differs significantly from traditional "full-service" carriers. Airlines like Delta, United, and American typically include at least one checked bag and a carry-on with most fares. Frontier instead offers lower starting prices and lets passengers add services à la carte. This approach appeals to leisure travelers carrying minimal baggage but can surprise those unfamiliar with the policy.

Practical Takeaway: Before booking a Frontier flight, calculate the total cost by adding your base fare plus all anticipated bag fees. Compare this total to competitors' all-inclusive pricing. You may find that a higher base fare with another airline actually costs less overall.

Carry-On Baggage Fees and What's Included

Frontier charges $35 for a carry-on bag when purchased during initial booking on most fares. If you add a carry-on bag after booking but before your flight, the cost increases to $40. At the airport on the day of travel, a carry-on bag costs $45. These prices apply to standard roller bags and similar-sized luggage.

The one item included free with all Frontier fares is your personal item. This must be small enough to fit under the seat in front of you. Examples include a purse, small backpack (approximately 14 inches wide by 8 inches deep by 8 inches tall), laptop bag, or briefcase. The airline measures personal items at check-in, and bags that don't fit are subject to carry-on fees.

Frontier allows one free personal item and one paid carry-on bag per person. If you travel with multiple pieces of luggage—for example, a small rolling bag plus a backpack—you would need to pay for the additional item. Some travelers minimize fees by consolidating belongings into a single personal item, then purchasing a carry-on only when necessary.

The timing of when you purchase a carry-on bag matters significantly. Booking the bag when you purchase your ticket saves $10 compared to purchasing at the airport. Many travelers can save money by committing to their baggage needs in advance. Additionally, Frontier's website and mobile app allow you to manage baggage options during the booking process, showing the exact cost before you complete your purchase.

Elite frequent flyer members receive benefits that may waive carry-on fees. Members of Frontier's loyalty program at higher tiers can receive free carry-on bags as part of their membership benefits. The Frontier Elite credit card also includes a free carry-on bag benefit, though this comes with an annual fee for the card itself.

Practical Takeaway: If you travel frequently on Frontier or anticipate multiple trips, evaluate whether the airline's Elite credit card saves money over time through free carry-on bags and other perks. Calculate the annual fee against your typical baggage costs to determine if membership or the credit card makes financial sense.

Checked Baggage Charges and Limits

Frontier charges $30 for the first checked bag and $40 for the second checked bag when purchased during booking. Like carry-on bags, prices increase if you add checked bags after purchasing your ticket. Adding a checked bag within 24 hours of your flight costs $35 for the first bag and $45 for the second. At the airport, first checked bags cost $40 and second checked bags cost $50.

Each checked bag can weigh up to 50 pounds and measure up to 62 inches (length plus width plus height). Bags exceeding these limits are subject to additional oversized baggage fees. Oversized items cost $100 each. Understanding these dimensions helps you pack efficiently and avoid unexpected charges. A standard rolling suitcase typically meets these requirements, but soft-sided bags or non-traditional luggage may exceed limits.

Frontier allows up to two checked bags per person, though additional bags beyond this limit face overage fees. The airline does not publicly specify overage fees on their website, so contact customer service directly if you need to check more than two bags. For most travelers, two checked bags provide sufficient capacity.

The airline includes free checked baggage for certain passengers: active-duty military personnel, elite frequent flyer members, and some credit card holders. Military passengers receive one free checked bag with valid military identification. Frontier's highest loyalty tiers provide free checked bags as a membership benefit. These exceptions can substantially reduce travel costs for frequent or long-distance trips.

Weight distribution across your bags helps you stay within limits. If one bag approaches 50 pounds, redistribute items to another bag. Scales at home or in retail stores allow you to weigh bags before arriving at the airport, preventing costly surprises. Many airports have scales near check-in counters where you can weigh bags before paying fees.

Practical Takeaway: For trips where you need checked baggage, calculate whether purchasing your first checked bag ($30 at booking) is cheaper than paying for extra carry-on luggage and consolidating belongings. For longer trips requiring multiple bags, compare the total baggage cost to alternative airlines that might include free bags with their base fare.

Seat Selection Charges and How to Minimize Costs

Frontier charges for most seat selections beyond the airline's "standard" seats. Standard seats are located in regular rows and cost nothing extra—you receive a random seat assignment at no charge. Preferred seats, which include extra legroom or forward positioning, cost $10 to $39 depending on the flight and seat location. Exit row seats typically cost more due to extra legroom. Seats near the front of the cabin cost more than those toward the rear.

The airline's website displays seat maps during booking, showing prices for each available seat. You can see exactly what you'll pay for seat selection before confirming your purchase. Many leisure travelers accept standard seat assignments at no cost, while business travelers or those with mobility needs may choose to pay for specific seats.

Frontier's pricing for seat selection fluctuates based on demand, similar to how airlines price tickets. A preferred seat on a full flight may cost more than the same seat on a less-crowded flight. Booking your flight well in advance sometimes provides more seat selection options at lower prices, though this varies.

Some travelers minimize seat selection costs by checking in online exactly 24 hours before their flight. This allows you to select from available seats at that time, and many free standard seats may still be open 24 hours before departure. Checking in early doesn't guarantee a preferred seat, but it improves your chances of getting a decent standard seat without paying extra.

For passengers with disabilities or medical conditions, Frontier provides accessible seating accommodations. Contact the airline directly rather than purchasing a seat online. The airline also allows passengers to request seat assignments near family members or traveling companions, though requests are not guaranteed and may involve fees.

Practical Takeaway: Unless you have specific seat needs, accept a free standard seat assignment. If you want better legroom or positioning, compare the cost of a preferred seat to the value it provides for your specific flight length. For flights under three hours, many travelers find the standard seat adequate and save money by declining seat purchases.

Other Charges: Beverages, Snacks, and Ancillary Services

Frontier does not include free beverages or snacks on most flights. The airline sells drinks, snacks, and meals à la carte. Soft drinks, bottled water, and alcoholic beverages are available for purchase. Snacks include items like cookies, pretzels, and chips. Prices typically range from $
