You’re booking a Frontier Airlines flight and concerned about baggage restrictions. Budget airlines are famous for strict baggage policies and surprise fees. Frontier airlines personal item size restrictions are real, and many travelers get caught off guard.
Frontier Airlines operates similarly to Spirit Airlines with strict baggage policies. Understanding their rules prevents costly mistakes. Let’s break down exactly what you need to know about Frontier’s baggage restrictions and fees.
Understanding Frontier’s Baggage Philosophy
Frontier Airlines built their business model around keeping base fares low. They offset this by charging for baggage. Understanding this philosophy explains their aggressive fee structure.
The frontier baggage policy charges for nearly everything beyond a personal item. Most traditional airlines include a free carry-on and personal item. Frontier charges for carry-on bags and all checked luggage.
The basic structure is:
- Personal item: Free with all tickets
- Carry-on bag: $29-39 depending on booking method
- First checked bag: $35-45
- Second checked bag: $45-55
This fee structure makes Frontier’s base fares appear cheap until you add baggage costs. Understanding the total cost prevents sticker shock at the airport.
Frontier Airlines Personal Item Size Specifications
The official frontier airlines personal item size limit is 17 inches (length) x 13 inches (width) x 8 inches (height). This equals 1,768 cubic inches of space.
This size is smaller than most major airlines allow. The restriction is tight but not impossible to work with. Many common bags fit within these dimensions.
The weight limit for personal items is 25 pounds. Most people never hit this limit. The size restriction is the real constraint travelers face.
Frontier measures bags at the gate and enforces the limits strictly. If your frontier airlines personal item size exceeds the limit, Frontier may charge you a fee or deny the item. Knowing the exact dimensions prevents gate disputes.
What Qualifies as a Frontier Personal Item
A frontier personal item can be:
- A small backpack or daypack
- A purse, shoulder bag, or crossbody bag
- A laptop bag or briefcase
- A small messenger bag
- A small diaper bag (like a coach diaper bag or similar small size)
- A small rolling carry-on if dimensions allow
The item must fit completely under the seat in front of you. If any part protrudes or sticks out, Frontier may reject it as a personal item.
Common items that exceed the size limit include standard rolling luggage, large hiking backpacks, and full-size duffel bags. These require paying for a carry-on option.
Frontier Carry On Size vs Personal Item
Many people confuse frontier carry on size with personal item dimensions. They’re different policies with different costs.
A carry on bag size with Frontier is 24 x 16 x 10 inches. This is larger than the personal item and costs $29-39 to bring on the plane. The fee varies depending on whether you purchase it during booking or at the gate.
The dimensional difference is significant. A carry-on is taller and wider than a personal item. The personal item is much more compact.
Frontier airlines carry on size is larger than their personal item allowance but smaller than traditional airline carry-ons. If you need more space than a personal item provides, you pay for the carry-on upgrade.
Frontier Carry On Fees and When to Buy
Purchasing a frontier carry on at booking costs $29 if booked online. Buying at the airport counter or gate costs $39. This price difference incentivizes purchasing in advance.
Many budget travelers skip the carry-on fee for short trips. For longer trips or when you have more luggage, the carry-on becomes necessary.
The math is simple: a $29 carry-on purchased at booking is significantly cheaper than a $100 gate check fee for an oversized item. Smart packing or advance planning saves money.
Frontier Baggage Fees Explained
Understanding frontier baggage fees helps you budget correctly for your trip.
The first checked bag costs $35 if purchased online, $45 at the airport. The second checked bag costs $45 online, $55 at the airport. Additional bags cost even more.
These fees add up quickly for families or travelers with multiple bags. A family of four checking two bags each incurs significant baggage costs.
Weight limits on checked bags are 50 pounds per bag. Bags exceeding 50 pounds incur overage fees of $25 per 5-pound increment.
Carry On Dimensions Compared to Other Airlines
Understanding carry on dimensions across airlines helps you choose the right luggage.
Frontier: 24 x 16 x 10 inches (with $29 fee)
Spirit: 22 x 18 x 10 inches (with $34 fee)
Southwest: 24 x 16 x 10 inches (free)
American: 22 x 14 x 9 inches (free)
United: 22 x 14 x 9 inches (free)
Frontier and Southwest allow the same dimensions, but Southwest includes carry-ons free. This illustrates how budget airlines monetize features that traditional airlines offer free.
Measuring Your Bag Correctly
Before traveling, measure any bags you plan to bring. The frontier airlines personal item size is specific and consistently enforced.
Use a tape measure or ruler. Measure from the outermost points: length (longest dimension), width (widest perpendicular dimension), and height (depth). Include wheels, handles, or any protrusions extending beyond the main bag.
Soft-sided bags compress slightly. Hard-sided bags cannot compress and must fit precisely within dimensions. A soft bag that’s marginally oversized might compress enough to pass inspection.
Test your bag in the sizer at the airport if possible. Many airports have size check devices near baggage claim. This confirms whether your personal item size meets requirements.
Comparing Frontier to Spirit Airlines
Frontier and Spirit Airlines are often mentioned together as budget carriers with similar baggage policies. Frontier airlines personal item size differs slightly from Spirit.
Spirit Airlines personal item size: 16 x 14 x 12 inches
Frontier Airlines personal item size: 17 x 13 x 8 inches
Spirit’s dimension is larger in two areas (length and width) but shorter in height (8 vs 12 inches). The volumes are similar. Both are significantly smaller than traditional airlines.
Frontier baggage fees and Spirit’s fees are comparable. Both charge $29-35 for carry-ons and $35-40 for first checked bags.
The main difference is Frontier allows slightly larger length and width in personal items but with less height. Spirit allows more height but slightly less length and width.
Packing Strategy for Frontier
Understanding these policies helps you pack efficiently.
For short trips using only a personal item:
- Use a compact backpack (16 x 12 x 7 inches approximately)
- Pack only essentials
- Wear bulky items rather than packing them
- Use compression bags to maximize space
- Minimize toiletries with travel sizes
- Choose lightweight clothing
For trips requiring more luggage:
- Purchase a carry-on at booking ($29)
- Use carry-on plus personal item
- Consider skipping checked bags if possible
- If checked luggage is necessary, budget the $35+ fee
Real Examples of What Size Bags Work
Understanding what size bags fit helps you shop correctly.
Fits as personal item:
- 16 x 12 x 7 inch backpack
- 15 x 10 x 6 inch laptop bag
- Standard purse or shoulder bag
- Small messenger bag
Doesn’t fit as personal item:
- 22 x 14 x 9 inch carry-on
- Standard rolling suitcase
- Large hiking backpack
- Full duffel bag
When in doubt, test items before traveling. Bring something slightly smaller than the limit to ensure approval.
Coach Diaper Bag as Personal Item
Parents often wonder if coach diaper bag or similar styles work as personal items. Most diaper bags fit the size limits.
A typical coach diaper bag is around 14 x 10 x 6 inches. This fits comfortably within Frontier’s personal item dimensions.
Diaper bags are practical personal items because they hold necessities for babies and young children. Frontier allows them when they meet size requirements.
Larger diaper bags may exceed limits. Check dimensions before traveling with a baby on Frontier.
Frontier Baggage Policy Enforcement
Frontier strictly enforces size restrictions. Gate agents measure items that appear close to limits.
The enforcement is consistent across flights and airports. You won’t receive warnings or second chances. If your item exceeds dimensions, you pay fees or check the bag.
Some travelers expect negotiation at the gate. Gate agents don’t negotiate. The policy is firm and consistently applied.
Arriving early helps. Earlier flights have more flexibility. Gate agents are stricter as departure time approaches and standby options diminish.
Frontier’s Total Cost Comparison
Understanding the complete cost structure matters when comparing airlines.
A Frontier flight base fare of $79 with a personal item is genuinely cheap. Add a carry-on ($29), first checked bag ($35), and second checked bag ($45), and the total baggage cost reaches $109. Your flight now costs $188 total.
A traditional airline flight of $149 might include free carry-on and personal item. No baggage fees. The traditional airline costs less despite higher base fare.
This comparison explains why some budget airline flights become expensive once baggage is factored in. Always compare total costs, not just base fares.
Tips for Flying Frontier Successfully

Arrive early: Show up early at the airport. Gate agents are stricter as departure approaches.
