The Best Unlimited Flight Passes for Frequent Travelers

Airfare usually takes up a big chunk of a vacation budget, but did you know some airlines offer an unlimited flight pass? This can be an especially intriguing option for those planning quite a bit of travel — while there are plenty of ways to find cheap flights, the cost of multiple trips in a year can quickly add up. But are these all-you-can-fly passes worth the upfront cost? Find out more about the best flight passes and how much they cost.

Frontier Airlines

In fall 2023, Frontier Airlines launched its GoWild! All-You-Can-Fly Pass. Those who purchase the pass can enjoy unlimited flights to any domestic or international destination the airline flies to. Before purchasing, be sure to check the airline’s extensive list of fees — but if you’re flexible and travel light, the potential savings with Frontier’s GoWild! Pass can be substantial.

Pros

• For each flight you take, you’ll pay a fare of just $0.01 plus taxes and fees.
• The GoWild! Pass features several options and price points. Monthly passes are available starting at $149, passes valid for only summer travel cost $499, and annual passes will set you back $599. (Prices accurate at time of publish in early 2025.)
• The airline also frequently runs limited-time specials with lower pricing for new members.

Cons

• Pass bookings can only be confirmed last-minute — one day before domestic departures and up to 10 days before international flights — which limits the appeal to travelers who can be spontaneous.
• Other restrictions to be aware of: Some blackout dates apply, availability on some routes may be limited, and bookings outside the one- or 10-day window may be possible for an extra fee.
• Because it’s a budget airline, Frontier charges extra for both carry-on and checked bags, as well as things like seat assignments or even printing your boarding pass at the airport.

Alaska Airlines

Based in Seattle, Alaska Airlines has an extensive route network on the West Coast. If you fly around Arizona, California, Nevada, or Utah frequently, then the airline’s Flight Pass may be worth the investment.

Pros

• Unlike Frontier’s subscription, Alaska’s pass doesn’t offer truly unlimited flights. There are options for six, 12, or 24 flights in a year — but that should still appeal to the majority of travelers.
• Alaska offers free seat assignments, and there are no change fees or blackout dates.
• The pricing is attractive: Passes start at $49 for six Alaska flights in a year (one roundtrip every two months), $99 for 12 flights (one roundtrip flight per month), and $189 for 24 trips (two flights a month).

Cons

• The pass is valid only for flights between 15 destinations in Arizona, California, Nevada, and Utah, so you’ll want to check those carefully and see if it makes sense for you. 
• You’ll receive a set number of credits that must be redeemed for flights before the end of the month (though travel can take place up to 90 days after you book a trip).

Southwest Airlines (Companion Pass) 

Southwest’s Companion Pass works a bit differently than the other passes on this list since it’s essentially a two-for-one pass — but it can unlock incredible value for two people traveling together.

Pros

• If you fly Southwest frequently, there’s no question the pass is worth it. Once you qualify, the Companion Pass is valid for the rest of the calendar year and the year after that.
• Once you choose your companion, they can fly with you to any of Southwest’s 120-plus destinations for just the cost of taxes and fees (starting at $5.60 one way).
• There are no blackout dates, and you can even change your companion up to three times in a calendar year.
• Unlike budget airlines, Southwest doesn’t (yet) charge extra for seat assignments or changes; each passenger can also check two bags for free.

Cons

• It’s a bit harder to obtain Southwest’s unlimited flight pass — typically, you’ll have to fly 100 qualifying flights on Southwest in a calendar year or earn 135,000 points (which include both flights and credit card purchases).
• However, one of the easiest ways to qualify is by keeping an eye out for the airline’s credit card promotions. Southwest frequently offers a bonus that includes a Companion Pass to those who sign up for one of its credit cards and meet the spending requirements and pay the annual fee. 

Air Canada and Porter Airlines

Fly to Canada frequently? Two Canadian carriers offer packages of prepaid flight credits that can be used within specific travel zones of your choosing.

Porter Airlines — which recently launched flights from Montreal and Toronto to U.S. destinations including Las Vegas, Los Angeles, and Orlando — offers what it calls the Porter Pass. Travelers can choose between 10, 20, 50, and 100 flight credits (valid for 365 days from date of purchase). Most packages are transferable, so you can also share them with others. You must sign up for the carrier’s frequent flier program to be eligible, and purchases will be made in Canadian dollars.

Air Canada’s Flight Pass works similarly — you must first choose a zone of travel (such as Canada to the U.S.) and a set number of flight credits. The program also offers an option for unlimited travel for a year. However, you must technically be a Canadian resident and a member of the airline’s frequent flier program to purchase.
