No—checked bags aren’t free on Frontier unless you buy a bundle, hold Frontier elite status, use the airline’s credit card perk, or qualify as active‑duty military.
Frontier builds low base fares and lets you add only what you need. That means a checked suitcase usually carries a fee. The good news: there are clean paths to get a free checked bag on specific tickets or with certain credentials. This guide spells out each path, plus sizes, weights, and smart ways to keep costs down.
Quick answer: Frontier checked bags and when they’re free
Most travelers pay for checked luggage on Frontier. Free checked bags appear in a few situations:
- You bought a Business bundle that includes two checked bags.
- You hold elite status high enough to unlock checked bag benefits.
- You’re active‑duty U.S. military traveling with valid ID.
- You’re the primary cardholder of the Frontier Airlines World Mastercard with the free checked bag benefit.
- You caught a limited‑time promo that explicitly adds a free checked bag to your itinerary.
What you get with a standard Frontier ticket
A standard Frontier fare includes one personal item only. That small bag must fit under the seat, and the size cap is 14 x 18 x 8 inches. Carry‑ons and checked bags are extras you add during or after booking. Checked bags must stay within 62 linear inches and 40 pounds unless your fare or status says otherwise. Frontier publishes these limits on its bag size and weight page, which lists the personal item cap, overhead bin dimensions for carry‑ons, the 40‑pound checked weight, and the surcharges for oversize and overweight pieces.
Table: who gets a free checked bag on Frontier
| Traveler or fare | Free baggage included | How it’s granted |
|---|---|---|
| Standard fare (no status) | Personal item only; checked bag not free | Base policy |
| Economy or Premium bundle | Carry‑on included; checked bag still paid unless stated on offer | Bundle features |
| Business bundle | Two checked bags, often up to 50 lbs each, plus seat upgrade perks | Bundle details |
| Frontier elite status | Gold: free carry‑on; higher tiers add free checked bag(s) | Member benefits |
| Active‑duty U.S. military | One free carry‑on and two free checked bags; oversize/overweight fees waived for the two free bags | Military waiver |
| Frontier Airlines World Mastercard (primary cardholder) | Two free checked bags on Frontier‑operated flights | Card benefit |
Tip: Fees and inclusions can shift by route and date. Always check the bag options shown during booking before you pay.
Are checked bags free on Frontier with status or bundles?
Short answer: sometimes. Frontier sells curated bundles, and it also rewards loyal flyers. Here’s how both routes can turn a paid suitcase into a free one.
Bundles: Economy, Premium, and Business
Frontier bundles package popular extras. Economy adds a carry‑on. Premium layers a seat upgrade and early boarding. Business is the standout for baggage: it includes two checked bags and the weight allowance for those bags rises to 50 pounds each instead of the usual 40. If your trip needs checked luggage both ways, that Business bundle can offset bag fees in one click while also giving you a more spacious seat.
When bundles are on sale, the math gets even friendlier. Frontier has run seasonal deals that throw in a free checked bag for nonstop trips during a defined window. Those are date‑limited promos, so they only count if your itinerary explicitly shows the free bag at checkout.
Elite status: Gold, Platinum, and Diamond
Frontier Miles status unlocks bags at different rungs. Gold starts you off with a free carry‑on. Platinum adds the first checked bag at the normal weight limit. Diamond steps it up to two checked bags. If you travel with family on the same reservation, many perks extend to companions listed on that booking. Status offers change from time to time, so glance at your account benefits before you pack.
Military: who qualifies and what you get
Active‑duty service members with valid ID receive generous baggage waivers on Frontier. The standard military allowance includes one free carry‑on and two free checked bags, and the airline waives oversize and overweight charges for those two free checked items. Veterans and retirees don’t receive the same waiver unless they’re traveling on active orders, so bring updated credentials if you expect to use the policy. Details live on the airline’s military bags policy. The waiver applies only to active‑duty travelers; family members follow the normal rules unless their fare or status adds benefits.
Credit card perk: two free checked bags
Frontier’s co‑branded World Mastercard adds a powerful baggage benefit for the primary cardholder on Frontier‑operated flights: two free checked bags. The perk applies to bags up to 40 pounds each, which matches the airline’s standard weight cap. Make sure your card is on the reservation and your Frontier Miles number is attached so the system prices your bags correctly during check‑in.
The rules that don’t change: sizes, weights, and cutoffs
Good packing starts with numbers. These are the core limits that govern bag acceptance across most tickets:
- Personal item: 14 x 18 x 8 inches, under‑seat size.
- Carry‑on: 24 x 16 x 10 inches, up to 35 pounds.
- Checked bag: up to 62 linear inches, up to 40 pounds unless your fare bumps that to 50.
- Overweight fees: charges apply at 41–50 pounds and again at 51–100; over 100 pounds isn’t accepted.
- Oversize fees: charges apply at 63–110 linear inches.
Online purchase windows matter too. You can usually add and pay for bags online up to about an hour before departure. Buying in advance keeps costs in check and speeds your airport drop‑off.
Smart ways to avoid surprise bag charges
You don’t need elite status to dodge extra costs. Use these tactics and you’ll keep your spend predictable.
Pick the right bundle for your trip
If you’re checking a suitcase roundtrip, the Business bundle’s two 50‑pound bags can outvalue stand‑alone bag purchases, especially on peak dates. If you’re traveling light, Economy or Premium may be plenty since both include a carry‑on that keeps fees off your cart.
Balance weight across bags
Frontier’s overweight fees kick in one pound after the limit. Slide heavy items to a second bag or your carry‑on to keep each checked piece at or under its cap. A small digital luggage scale pays for itself the first time it keeps you from crossing 41 pounds.
Use the free personal item well
That under‑seat bag is included on every ticket. Choose a soft‑sided tote or small backpack that maximizes the 14 x 18 x 8‑inch outline. Pack dense items there—chargers, meds, a light jacket—and free up space in your suitcase.
Know what must stay out of checked bags
Spare lithium batteries and power banks belong in your carry‑on. Liquids over 3.4 ounces go in checked luggage, while travel‑size liquids in your carry‑on must fit the quart‑size 3‑1‑1 rule. Keep IDs and valuables with you, not in a checked bag. Frontier’s sizing and weight rules linked above are a handy pre‑trip checklist for bag prep as well.
Table: where you buy your bag and what you’ll usually pay
| Purchase point | Relative cost | What to expect |
|---|---|---|
| During booking | Lowest | Best price and widest choice of seats and bundles |
| Post‑booking online or in app | Low | Still below airport pricing; easy to tweak quantities |
| Airport kiosk or counter | Higher | Pay more and spend time in line |
| At the gate | Highest | Strict size checks and last‑minute fees if a bag won’t fit overhead |
Are checked baggage fees waived on Frontier for military flyers?
Yes, for active‑duty travelers with valid ID. The waiver covers one carry‑on and two checked bags, and the oversize and overweight charges don’t apply to those two free checked pieces. If you’re moving with tough‑to‑pack gear, that extra flexibility helps. The waiver applies to Frontier‑operated flights, so third‑party flights on the same itinerary may have different rules.
How to pick the cheapest path for your trip
Every trip is different, so start from your packing list and run the numbers shown at checkout.
One way with one suitcase
If you only need one checked bag, buy it during booking. Prices rise as you move toward departure, and at the gate they’re steep. If a bundle is only a few dollars more than a stand‑alone bag, grab the bundle and enjoy the extra perks.
Roundtrip with two bags
Business bundle wins often here. Two checked bags included each way trims line time and stops the scale stress at 50 pounds. If you already hold Platinum or Diamond status or the Frontier credit card, you may already have free checked bags—stacking beyond what your ticket includes won’t add more freebies, so let the system choose the better deal.
Family trip with mixed needs
Put the heaviest packer on the reservation with status or the card benefit, since many perks extend to companions on the same record locator. Then buy one extra checked bag if needed and lean on carry‑ons included in your bundle. A shared packing list prevents duplicate items and keeps everyone under the limits.
Packing rules that save time and money
- Photograph your bag’s contents before you close the zipper. If a bag goes missing, those pictures speed up claims and reimbursements.
- Place itinerary and contact info inside the suitcase. External tags can tear off.
- Use hard tags on checked bags and a bright strap so your suitcase stands out on the belt.
- Lock your bag with TSA‑approved locks, or use zip‑tie tags you can snip on arrival.
- Put a copy of your hotel address in the front pocket to help rerouting if a tag smudges.
What happens if Frontier delivers your bag late or damaged?
U.S. rules require airlines to compensate travelers for reasonable expenses when a checked bag is delayed, and for loss or damage when bags don’t make it. Save receipts for essentials you buy while waiting, and file a written claim with Frontier within the time window noted on your receipt. If the bag fee was charged and the bag arrives late, you may be due a refund of that fee along with expense reimbursement. For international trips, compensation follows treaty limits that vary by route. You can read the Department of Transportation’s guidance for travelers on its lost, delayed, or damaged baggage page and use those steps if you need to escalate a claim.
Quick reference: sizes, fees, and best practices
- Measure before you pack. The checked size limit is 62 linear inches. If your suitcase is close, grab a tape measure and add the three sides to avoid oversize charges.
- Aim for 38–39 pounds on standard tickets for a buffer below the 40‑pound cap.
- Keep lithium spares, matches, and lighters out of checked bags. Put meds in your personal item.
- Add bags online as soon as your plans firm up. Prices online beat airport rates.
- Screenshot your bag selections and the checkout page so you can prove what you bought if systems hiccup.
Bottom line: when will Frontier checked bags be free for you?
Most of the time, they won’t be. They do turn free when you buy a Business bundle, hold the right Frontier status tier, qualify as active‑duty military, or carry the airline’s World Mastercard as the primary cardholder. Watch for limited‑time promos that add a free bag to nonstop tickets, and always price bags during booking to lock the lowest rate. With the right mix of bundle, status, or waiver, you can bring a suitcase without paying a dime—and still keep your fare low.
