Frontier Airlines Baggage Fees Guide 2026

Frontier Airlines operates as an ultra-low-cost carrier, keeping base ticket prices affordable by charging separately for most baggage services. Passengers receive one free personal item, but everything else—from carry-on bags to checked luggage—incurs fees that rise based on when and where you pay. Understanding these rules helps travelers budget effectively and avoid hefty airport surcharges.

Personal Item: The Only Free Allowance

Every Frontier passenger can bring one personal item at no cost. This must fit under the seat in front of you and measure no larger than 18 inches high, 14 inches wide, and 8 inches deep, including handles, wheels, and straps. Examples include small backpacks, purses, or laptop bags. Frontier may measure items during boarding, and oversized personal items could face carry-on fees.

Carry-On Bag Requirements and Pricing

A carry-on bag must not exceed 24 inches high, 16 inches wide, and 10 inches deep (61 linear inches total), with a maximum weight of 35 pounds. Fees depend on purchase timing:

• Pre-booked online: $30–$62
• During online check-in: $54–$74
• Airport check-in or kiosk: $79
• Gate-checked: Up to $99

Bags exceeding size or weight limits get checked at the gate for the highest fee. Certain bundles like Economy or higher fares include a carry-on for free.

Checked Luggage Fees and Limits

Checked bags have a standard size limit of 62 linear inches (length + width + height) and weight caps varying by source, generally 40–50 pounds. Fees escalate with additional bags and timing:

Data compiled from multiple sources shows variability; always check Frontier’s bag price checker for exact routes. Business fares include two checked bags up to 50 pounds each.

Overweight Baggage Charges

Bags over the standard weight face extra fees, applied per bag per direction on top of base charges. Policies updated for 2026:

• 41–50 pounds: $75
• 51–99.99 pounds: $100 (pre-April 4, 2026 bookings) or $129 (post-April 4, 2026)
• Over 100 pounds: Not accepted

Pack light to dodge these costs, as they add up quickly on round trips.

Oversized Luggage Penalties

Bags exceeding 62 linear inches but under 110 inches incur a $75 fee per bag per direction, plus any other applicable charges. Items over 110 linear inches or 100 pounds are prohibited. Special items like bicycles ($75) or antlers ($100) have unique rules.

Fare Bundles and What They Include

Frontier offers tiered bundles to simplify baggage costs:

• Basic: Personal item only.
• Economy: Adds carry-on bag.
• Premium: Carry-on plus perks like priority boarding.
• Business: Carry-on, two checked bags (50 pounds each), and lounge access.

Purchasing bundles during booking often saves 20–50% compared to à la carte fees at the airport.

Strategies to Cut Baggage Expenses

Minimize fees with these tips:

1. Prepay online: Booking bags at ticket purchase yields the lowest rates, sometimes 40% less than airport prices.
2. Choose bundles: Economy or higher fares bundle baggage affordably for frequent packers.
3. Pack minimally: Stick to personal item dimensions; use compression bags or lightweight luggage.
4. Ship alternatives: Services like LugLess offer carry-on delivery for $14–$55, potentially cheaper for heavy items.
5. Weigh early: Use a home scale to avoid overweight surprises.

Fees fluctuate by route, demand, and date—use Frontier’s tools for precise quotes.

Special Items and Sports Equipment

Frontier permits certain non-standard items with fees:

• Bicycles: $75 (disassembled, boxed).
• Surfboards/kayaks: Oversized fees apply.
• Antlers: $100.
• Pets/strollers: Separate policies.

Always confirm via Frontier’s optional services page, as rules evolve.

Changes in 2026 Baggage Policy

As of April 4, 2026, overweight fees for 51–99.99-pound bags rose to $129 from $100, reflecting adjustments for heavier operational costs. No changes to size limits, but digital check-in incentives encourage early prepayments.
