Frontier Airlines checked baggage weight & size rules.

Did you know your checked bag’s weight could determine how smooth or expensive your Frontier Airlines journey turns out to be? Frontier Airlines is known for its ultra-low fares, but that also means every inch of your luggage counts. Understanding Frontier Airlines baggage weight and size limits isn’t just about following the rules-rather, it’s about traveling smarter and saving more money. 

Whether you’re a light and organised packer or someone who brings it all, knowing about what and how much is allowed can help you avoid last-minute repacking and save you from costly airport fees. Frontier’s checked baggage policy clearly outlines how much you can bring in your luggage, what size counts as standard, and what happens if you exceed the given limits. 

This blog by Affluence Travels walks you through the checked baggage dimensions through smart planning. So, before you zip up that suitcase, let’s unpack everything that you need to know for ensuring your journey feels light, easy, and stress-free with Frontier Airlines. 

Frontier Airlines Checked Baggage Weight Limit

For checked bags on Frontier, the standard weight limit is 40 lbs (about 18 kg) or less.

If your bag weighs more than 40 lbs, you’ll face oversize or overweight fees:

• 41-50 lbs: additional fee of $75

• 51-100 lbs: additional fee of $100

• Over 100 lbs: bag not accepted

It’s worth noting that for certain international travel, such as flights to and from Canada, different rules may apply — with a maximum limit of 70 lbs in some cases.

So before you zip up your suitcase, check your bag’s weight at home using a luggage scale to avoid surprise charges at check-in.

Frontier Airlines Checked Baggage Size Limit

In addition to weight, there is a size limit for checked bags. The total linear inches (length + width + depth) must not exceed 62 linear inches for standard checked baggage.

If your bag’s dimensions are bigger:

• 63–110 linear inches: oversize fee applies ($75)

• Over 110 linear inches: bag not accepted

When you choose your luggage, check the size label or measure the external dimensions, including wheels, handles, and straps. Staying within the 62-inch limit ensures your bag qualifies under the standard allowance.

Frontier Airlines Checked Baggage Fees

While the size and weight limits define what’s allowed, the cost of checking the bag depends on when and how you purchase the option. Frontier encourages passengers to buy baggage allowance during booking to get the lowest rate.

Key points to remember:

• Add checked bags during booking or online check-in to get the lowest fee.

• Waiting until airport check-in or gate means higher fees.

• Oversized and overweight fees are charged in addition to standard bag fees.

Therefore, we recommend checking your baggage cost while booking your ticket to budget smartly and avoid last-minute surprises.

Pack within limits for a seamless check-in and explore top tips for affordable last-minute flight bookings to add bags cheaply even if plans change suddenly.

Oversized and Overweight Baggage Rules

If your checked bag exceeds the standard limits, Frontier’s policy is straightforward:

• Weight over 40 lbs up to 50 lbs: $75 extra fee

• Weight 51-100 lbs: $100 extra fee

• Weight over 100 lbs: not accepted

• Size over 62 linear inches but up to 110 inches: $75 oversize fee

• Size over 110 linear inches: not accepted.
  
  

Frontier allows up to six checked bags per passenger per trip, subject to operational restrictions. So if you’re traveling with a group or carrying heavy gear, you’ll need to pay separately for each bag and make sure all stay within limits.

To avoid refusal or added costs, always weigh and measure your luggage before heading to the airport.

Tips to Avoid Baggage Fees and Travel Hassles

Here are some practical tips from Affluence Travels to keep your trip smooth and cost-efficient:

• Weigh your bag at home: Use a luggage scale to make sure it’s within the 40 lbs limit.

• Measure all dimensions: Include wheels, handles, and straps to ensure your bag doesn’t exceed 62 linear inches.

• Purchase checked bags early: It’s cheaper to buy during booking or online check-in.

• Pack smart: Use compression bags and avoid bulky items. Shift heavier items to your carry-on if possible.

• Check international rules: Flights to or from Canada may allow up to 70 lbs per bag.

• Explore bundle options: Some Frontier bundles may include one checked bag, which can save money.

• Avoid last-minute surprises: Oversize and overweight fees are steep—plan ahead.

• Check special items: Sports gear, musical instruments, or fragile items may have different policies.

How to Add or Manage Checked Bags with Frontier Airlines

Adding or managing checked bags with Frontier is easy and can be done at multiple stages of your journey:

1. During booking: Add your checked bag directly while purchasing your ticket.

2. After booking: Use the “Manage Trip” option on Frontier’s website or mobile app to add luggage before check-in.

3. Online check-in: You can still add bags here at a lower rate compared to airport pricing.

4. At the airport counter or gate: Bags can be added, but fees are significantly higher, and size/weight rules remain the same.
   
   

Tip: Always add your bags early for the most cost-effective experience.

The 40 lbs standard applies to most domestic routes, but confirmed via affordable flight tickets when booking Frontier to bundle and avoid per-bag surprises.

Important Exceptions and Special Items Policy

While the standard checked bag follows the 40 lbs and 62-inch rule, there are a few exceptions and special cases to note:

• International flights: Certain routes, like those to and from Canada, may allow up to 70 lbs per bag.

• Military personnel: Active U.S. military members and eligible family members with valid ID may receive up to two free checked bags and waived oversize or overweight fees (within standard limits).

• Special items: Sports gear, musical instruments, and fragile or oversized items are allowed but may require additional fees or handling.

• Smart luggage: Bags with lithium batteries or charging ports may face restrictions, so always confirm before packing.
  
  

Checking the “Special and Fragile Items” section on Frontier’s website before you travel can help avoid last-minute complications.
