Frontier Airlines Carry-On Size: A Complete 2025 Guide for Travelers

When you fly with Frontier Airlines, understanding carry-on rules can save both time and money. The airline keeps fares low by offering basic tickets and charging separately for extra services. That means your bag size really matters. If your suitcase is too big or heavy, you may have to pay extra at the gate. Knowing the limits before you pack helps you breeze through security and keep your travel budget intact.

Frontier Airlines Carry-On Size and Weight Rules

Frontier allows one personal item for free. A standard carry-on comes with a fee. Because space on board is limited, each inch counts.

Key Rules

• Personal Item: 14 × 18 × 8 inches (max). Must fit completely under the seat.

• Carry-On Bag: 24 × 16 × 10 inches (including wheels + handles).

• Weight Limit: No fixed rule, but you must lift it yourself into the overhead bin.

• Gate Check Fee: Oversized bags may be charged up to $75 if found non-compliant.

Tip: Measure your luggage at home with a tape measure before leaving. Frontier staff are known for checking sizes closely.

What Counts as a Personal Item

Your free personal item is perfect for essentials you’ll want nearby during the flight. It should slide neatly under the seat in front of you.

Common Examples

• Small backpack or daypack

• Laptop bag or briefcase

• Purse or handbag

• Camera bag

• Compact duffel bag

Try to keep valuables like passports, electronics, and medications inside this smaller bag for easy access.

Carry-On Fees and How to Save Money

Frontier’s pricing model separates tickets from add-ons such as baggage. Booking smartly can cut your costs dramatically.

Ways to Save

• Add Online Early: Buy your carry-on while booking your ticket. Prices start near $45 but rise closer to departure.

• Bundle Up: Frontier’s The Works and The Perks packages include carry-on, checked bag, and seat selection.

• Avoid Gate Payments: Paying at the airport may cost $75 or more.

• Sign Up for Emails: Frontier often releases limited-time baggage discounts.

Booking your flight and baggage together through Affluence Travels ensures transparent pricing and real-time savings.

Tips for Packing Your Carry-On Efficiently

Travelling light doesn’t mean leaving essentials behind. Smart organization helps everything fit neatly within the allowed dimensions.

Practical Packing Tips

• Roll, don’t fold clothes to save space.

• Wear bulky jackets and sneakers instead of packing them.

• Use travel-size toiletries (3.4 oz each max).

• Organise with packing cubes.

• Keep documents and electronics on top for security checks.

Many travellers also carry a small digital scale to confirm weight before heading to the airport.

Carry-On Allowance for Frontier Airlines Flights

When booking Frontier Airlines flights, remember that only one personal item is free. Standard carry-ons come with an extra fee unless you’ve purchased a bundle.
Through Affluence Travels, you can compare fares, baggage options, and upgrade bundles in one place, helping you choose the best combination of price and comfort. Frontier’s strict policy rewards travellers who plan ahead.

What Happens if Your Carry-On Is Oversized

Oversized luggage often causes delays and surprise costs. Frontier’s gate staff use sizing boxes to test bags before boarding.

If Your Bag Is Too Large:

• It will be tagged and checked into the hold.

• You’ll pay a gate fee depending on the extra size. 

• Refunds for pre-paid carry-on fees are not given.

To stay worry-free, measure twice and pack once.
