Flying ultra-low-cost carriers can save hundreds of dollars, but baggage fees often surprise travelers at the airport. One of the biggest changes affecting budget flyers today involves the carry-on policy at Frontier Airlines. Travelers booking the airline’s Basic Fare now typically pay for standard carry-on bags, while only a small personal item remains free.
Understanding Frontier’s carry-on rules before booking can help you avoid expensive airport charges, boarding delays, and unnecessary stress. This guide explains exactly what is free, what costs extra, how size limits work, and how to minimize fees while staying compliant with airline policies.
Understanding Frontier’s Carry-On Policy
Frontier operates under an ultra-low-cost carrier (ULCC) business model. That means the airline keeps base ticket prices low while charging separately for extras such as:
- Carry-on baggage
- Checked luggage
- Seat selection
- Priority boarding
- Flight flexibility
Under most Basic Fare tickets, Frontier allows passengers to bring:
- One free personal item
- No free full-size carry-on bag
A standard carry-on bag generally requires an additional fee unless included through:
- Elite status
- Bundle packages
- Promotional fares
- Specific memberships
This structure differs from traditional airlines that often include a free overhead-bin carry-on in the ticket price.
What Counts as a Free Personal Item?
Every Frontier passenger can bring one personal item at no charge.
Frontier Personal Item Size Limit
According to Frontier’s published policy, the maximum dimensions are:
| Item Type | Maximum Size |
|---|---|
| Personal Item | 14″ H × 18″ W × 8″ D |
The item must fit completely under the seat in front of you.
Examples of Allowed Personal Items
Common acceptable items include:
- Small backpacks
- Laptop bags
- Purses
- Diaper bags
- Compact duffel bags
-
Tote bags
What Is Considered a Carry-On Bag?
A carry-on bag is any larger item stored in the overhead compartment.
Frontier Carry-On Size Limit
| Bag Type | Maximum Dimensions |
|---|---|
| Carry-On Bag | 24″ H × 16″ W × 10″ D |
This includes:
- Wheels
- Handles
- External pockets
Weight Limit
Frontier generally limits carry-on bags to:
- 35 pounds (15.8 kg)
Exceeding size or weight restrictions can trigger additional fees at the gate.
Why Frontier Charges for Carry-Ons
Frontier’s pricing model allows travelers to pay only for services they actually use. The airline argues this approach benefits passengers who travel light.
Passengers carrying only a personal item can often purchase very low base fares compared with legacy airlines.
However, travelers bringing larger luggage may find total costs rise quickly after add-on fees.
How Much Does Frontier Charge for Carry-Ons?
Carry-on fees vary based on several factors:
- Route
- Demand
- Booking timing
- Purchase channel
- Travel season
Typically:
- Buying a carry-on during booking costs less
- Adding baggage later costs more
- Paying at the airport or gate costs the most
Estimated Frontier Carry-On Fee Range
| Purchase Time | Typical Cost Range |
|---|---|
| During Booking | $35–$60 |
| Before Check-In | $45–$70 |
| At Airport Counter | $79+ |
| At Gate | $99+ |
Prices fluctuate frequently.
Based on publicly available information, there is no confirmed fixed carry-on price that applies to every Frontier flight.
Why Gate Fees Are So Expensive
Frontier aggressively enforces baggage rules at the boarding gate. Gate fees are intentionally higher because they:
- Slow boarding
- Create operational delays
- Require last-minute baggage handling
Many travelers report paying nearly double the online baggage rate after their personal item failed the size check.
Frontier’s Bag Sizer: What Travelers Should Expect
At the gate, Frontier staff may ask passengers to place bags into a metal sizing bin.
If the bag:
- Fits fully inside → usually approved
- Sticks out → may be classified as a paid carry-on
Even slightly oversized bags can trigger charges.
Common Traveler Mistakes
Passengers frequently get charged because of:
- Overstuffed backpacks
- Expanded luggage compartments
- Wheels exceeding dimensions
- Bulging side pockets
Step-by-Step: How to Avoid Frontier Carry-On Fees
1. Measure Your Bag Before Leaving Home
Use a tape measure and include:
- Wheels
- Handles
- Straps
2. Choose a Personal-Item-Friendly Backpack
Many travel backpacks are specifically designed for Frontier’s dimensions.
Look for:
- Soft-sided materials
- Compression straps
- Under-seat sizing
3. Wear Bulkier Clothing
Jackets, hoodies, and boots reduce baggage volume.
4. Use Packing Cubes
Packing cubes compress clothing and improve organization.
5. Avoid Overstuffing
A soft backpack may technically meet dimensions but fail the sizer if bulging outward.
6. Purchase Bags Early
Buying luggage during booking is almost always cheaper than paying later.
Best Bags for Frontier Personal Item Travel
Travelers who frequently fly Frontier often use:
| Bag Style | Why It Works |
|---|---|
| Soft backpack | Flexible fit |
| Small duffel | Compresses easily |
| Underseat roller | Designed for budget airlines |
| Laptop backpack | Multi-purpose use |
Hard-shell luggage is riskier because it cannot compress inside sizing bins.
Frontier vs Other Airlines Carry-On Rules
Here’s how Frontier compares with major U.S. airlines.
| Airline | Free Personal Item | Free Carry-On | Basic Economy Restrictions |
|---|---|---|---|
| Frontier | Yes | No | Carry-on costs extra |

| Southwest | Yes | Yes | More generous policy |
| Delta | Yes | Yes | Usually included |

Ultra-low-cost carriers rely heavily on ancillary revenue from baggage fees.

- Carry-on bags
- Seat selection

These perks can significantly reduce overall travel costs for frequent flyers.
Frontier Carry-On Rules for Families
Families should know several important exceptions.
Diaper Bags
Traveling with infants generally allows:
- One diaper bag in addition to the personal item
Strollers and Car Seats
Most airlines, including Frontier, permit:
- Gate-checking strollers
- Gate-checking approved car seats
Medical Devices and Mobility Aids
Under U.S. federal regulations, medically necessary devices generally do not count against baggage limits.
Examples include:
- CPAP machines
- Wheelchairs
- Walkers
- Mobility aids
Travelers should still verify specific policies directly with Frontier before departure.
TSA Rules Still Apply
Even if your bag meets Frontier’s size rules, you must still comply with Transportation Security Administration security regulations.
Important TSA Carry-On Restrictions
Liquids Rule
Passengers must follow the TSA 3-1-1 liquids rule:
- Containers under 3.4 oz (100 mL)
- One quart-sized bag
- One bag per traveler
Prohibited Items
Restricted items may include:
- Large knives
- Firearms
- Explosives

Travelers should review official TSA guidance before flying.
International Frontier Flights and Carry-On Rules
Frontier’s baggage policies generally remain similar on international routes.
However:
- Fees may differ
- Customs requirements vary
- Weight restrictions can change
Always review the specific route details during booking.
Hidden Costs Travelers Often Forget
Budget airlines sometimes appear cheaper upfront but become more expensive after extras.
Common Additional Costs
| Extra | Possible Fee |
|---|---|
| Carry-on bag | $35–$99+ |
| Checked bag | Additional fee |
| Seat assignment | Optional fee |
| Priority boarding | Optional fee |
| Airport printing | Extra charge |
Comparing total trip cost—not just base fare—is essential.
Real-World Example: How Fees Add Up
Consider two travelers flying the same route.
Traveler A
- Basic Fare only
- Small backpack
- No seat selection
Total extra fees: $0
Traveler B
- Carry-on bag
- Checked bag
- Seat selection
- Airport baggage payment
Total extras may exceed the original airfare.
This explains why experienced Frontier travelers often pack extremely light.
