Frontier Airlines Bag Policy 2026 | Sizes & Fees
Flying Frontier and want to know what actually comes free under the official frontier airlines bag policy? Unlike most major carriers, Frontier only includes a personal item at no charge — everything else, including a standard overhead carry-on, costs extra. Knowing the exact bag sizes, weight limits, and booking your bags early can save you real money at the airport.
Quick Answer: Frontier Airlines Bag Policy at a Glance
Frontier includes one free personal item per passenger on all fares. Carry-on bags in the overhead bin and checked bags both require an additional fee, whether purchased in advance or at the airport. Under the official frontier airlines bag policy, personal items and carry-ons are both capped at 35 lbs; checked bags are capped at 40 lbs — stricter than the 50 lbs many other airlines allow.

Important notes: Frontier explicitly measures personal item sizing at the gate using sizing bins, and gate purchases of carry-on or checked bags cost significantly more than booking online in advance — always add bags through My Trips or at booking rather than waiting.

Official Frontier Airlines Bag Policy Overview
One personal item is included with all Frontier fares at no charge, sized up to 18″ × 14″ × 8″ and 35 lbs, including handles, wheels, and straps. A carry-on bag, sized up to 24″ × 16″ × 10″ and 35 lbs, must be added when booking or purchased separately — it’s never included free under standard frontier airlines bag policy rules. A checked bag, up to 62 linear inches and 40 lbs, also requires a separate purchase, and Frontier recommends buying it at least 60 minutes before your flight. Bags purchased during booking or in advance through My Trips cost less than bags purchased at the airport counter or gate.
What Makes This Frontier Policy Different
Frontier’s structure is a genuine outlier among U.S. carriers: while most airlines include a free personal item and a free carry-on, Frontier only includes the personal item — the overhead carry-on bag is always a paid add-on, regardless of fare type. Frontier also caps checked bags at 40 lbs rather than the 50 lbs standard used by most legacy carriers, meaning a bag that would be fine on another airline could trigger an overweight fee here. The airline is also notably strict about gate-side sizing enforcement, using dedicated sizing bins to measure personal items before boarding.
Allowed Bags and Size Limits Under Frontier Airlines Bag Policy
Review the breakdown of allowed bag types, maximum dimensions, and fee guidelines under the official frontier airlines bag policy:
| Bag Type | Status | Max Size & Weight | Rules & Conditions |
|---|---|---|---|
| Personal Item | Free / Included | 14″H × 18″W × 8″D, max 35 lbs | Must fit under the seat in front; purse, tote, small backpack, or laptop bag. |
| Carry-On Bag | Paid Add-On | 24″H × 16″W × 10″D, max 35 lbs | Overhead bin storage; purchase online in advance for lowest price. |
| Checked Bag | Paid Add-On | 62 linear inches, max 40 lbs | Standard checked limit is 40 lbs; overweight fees apply if over 40 lbs. |
| Military Luggage | Free (Active Duty) | 1 personal item, 1 carry-on, 2 checked (50 lbs) | Complimentary with valid active-duty U.S. military ID. |
Personal Item (Free)
Included with every fare, the allowed frontier airlines personal item size can measure up to 18″ × 14″ × 8″ (or 14″H × 18″W × 8″D) and weigh up to 35 lbs, including handles, wheels, and straps. It must fit completely under the seat in front of you — a purse, laptop bag, or small backpack are typical examples.
Carry-On Bag (Paid)
A carry-on bag can measure up to 24″ × 16″ × 10″ and weigh up to 35 lbs, but it’s never free — it must be added during booking or purchased separately, ideally in advance to avoid a steeper frontier airlines carry-on fee at the airport. Adding “Board First” guarantees overhead bin space by boarding with Group 1.
Checked Bag (Paid)
A checked bag can measure up to 62 linear inches (length + width + depth combined) and weigh up to 40 lbs. Frontier recommends purchasing it at least 60 minutes before your flight, and pricing is lower when purchased during booking or through My Trips rather than at the airport.
Military Exceptions
Active-duty U.S. military personnel receive one free personal item, one free carry-on bag, and two free checked bags (up to 50 lbs each) upon showing a valid military ID.
Prohibited/Extra-Fee Items
- Unpurchased carry-on bags: Any carry-on bag brought without being purchased in advance is charged at higher gate pricing.
- Oversized personal items: Personal items exceeding 18″ × 14″ × 8″ or 35 lbs are charged an oversized fee at the gate.
- Overweight/oversized checked bags: Checked bags exceeding 62 linear inches or 40 lbs trigger substantial excess luggage fees.
- Airport counter / gate purchases: Bags added at the airport counter or boarding gate are priced significantly higher than online advance purchases.
How Security Screening Works
Standard TSA airport security screening applies to Frontier passengers like any other airline, including the 100ml liquid rule for carry-on and personal items. Frontier’s own additional check happens at the gate, where personal item sizing is verified using dedicated sizing bins — a bag that doesn’t fit is charged an oversized fee on the spot, so it’s worth measuring your bag before you leave home rather than testing the limit at boarding.
Packing Strategy for Faster Entry
- Measure your personal item: Check your bag against 18″ × 14″ × 8″ and 35 lbs before you leave, since Frontier checks this precisely at the gate.
- Book bags online early: If you need a carry-on or checked bag, purchase it during booking or through My Trips — never wait for the airport, where the frontier airlines carry-on fee and bag rates are much higher.
- Check in bags at least 60 minutes prior: Purchase your checked bag at least 60 minutes before your flight, per Frontier’s own recommendation.
- Have military ID ready: If you’re active-duty military, bring your valid military ID to claim your free personal item, carry-on, and two checked bags.
- Travel ultra-light: Pack to fit everything into the free personal item allowance if you’re trying to avoid bag fees entirely — many travelers manage this for short trips.
- Add Board First: Add “Board First” alongside your carry-on purchase if you want guaranteed overhead bin space.
Security Check Anxiety Tips
If airport processes make you anxious, knowing that Frontier measures personal items strictly at the gate — using an actual sizing bin, not just a visual check — means it pays to measure your bag at home rather than hoping it’s “close enough.” Booking any carry-on or checked bag online well before your flight, rather than waiting until the gate, removes one major source of last-minute stress and cost. Packing light enough to fit only the free personal item sidesteps the bag-fee question entirely for shorter trips.
Day-of Entry Tips From BagPolicyInfo
- Only the personal item is free: Unlike most airlines, Frontier’s carry-on is always a paid add-on, never included.

- Gate prices are the most expensive: Book bags online during booking or through My Trips for the lowest cost.

- Military travelers get real perks: Free personal item, carry-on, and two 50-lb checked bags with a valid ID.
