The 10 Best Airline Affiliate Programs for 2026

Here's the uncomfortable truth about airline affiliate programs: the four biggest US carriers — Delta, American, United, and Southwest — have no affiliate program for flight bookings. Across the 141 airline programs in our database, the average EPC is $1.01, and commissions typically run 0.5-2%, often calculated only on the base fare (excluding taxes and fees that can double the ticket price).

But airline content is some of the highest-intent traffic on the web. Someone researching "best flights to Paris" is about to spend thousands on travel. The real question isn't which airline program pays the most — it's how you monetize the entire trip. Direct airline commissions are the smallest slice of what smart publishers earn from flight content.

This guide is structured around that revenue stack. We start with the elephant in the room (the Big Four US carriers have no flight programs), then work through each tier from highest payout to lowest, ending with a reference section covering the 10 best direct airline programs for publishers who want the complete picture.

What About the Major US Airlines? Delta, American, United & Southwest

None of the Big Four US carriers have an affiliate program for flight bookings. This is the single most important fact most airline affiliate guides get wrong. United and Southwest have vacation package and loyalty programs; Delta and American have nothing. The real monetization path for all four is credit cards and OTAs.

Delta Air Lines has no public affiliate program for flights or vacation packages. We confirmed this across every major network: CJ, Rakuten, Awin, Impact, ShareASale, FlexOffers. The monetization path is co-branded Delta SkyMiles American Express cards (Blue, Gold, Platinum, Reserve) available through Amex's affiliate program on CJ and Awin, with typical payouts of $50-$200+ per approved application. Delta SkyMiles points purchases via Points.com may also be available on FlexOffers.

American Airlines also has no public affiliate program. AA Vacations operates through travel agents, not publisher affiliates. Your options: Citi AAdvantage and Barclays AAdvantage Aviator co-branded cards on CJ, Bankrate, and CardRatings ($50-$175+ per approval), or promoting AA flights via OTA affiliate programs like Expedia or CheapOair.

United has no affiliate program for flight bookings. What exists is United Vacations (vacation packages only) on CJ at 0.50-1.00% (tiered), Mavely at 0.7% domestic / 1.4% international, and Skimlinks at ~2%. Multiple top-ranking sites incorrectly claim 2% commissions through Impact Radius — the official network is CJ, and the base rate is 0.50%. The average basket is $2,186, but a 24% reversal rate (commissions paid after travel, not at booking) erodes earnings significantly. Social media promotion is prohibited. CJ's terms require you to market as "United Vacations," not "United Airlines." A separate MileagePlus Points.com program on FlexOffers pays ~2% on loyalty points purchases with a near-zero EPC ($0.02). We cover this in detail in our full United Airlines affiliate program analysis.

Southwest has no affiliate program for flight bookings. We checked every major network and confirmed this in our full Southwest Airlines affiliate program analysis. What exists: Southwest Vacations (vacation packages only, not flights) on Mavely at 2.8% and CJ at just 0.50% — but this program appears to be winding down as Southwest launched Getaways by Southwest in mid-2025, bringing packaging in-house. A Rapid Rewards Points.com program on FlexOffers pays ~2% on loyalty points purchases but has a $0.00 EPC. Your best option for Southwest flight traffic is aggregators (Kayak, Expedia) now that Southwest joined major metasearch platforms in 2024-2025. Chase Rapid Rewards cards (Plus, Premier, Priority) are available through CardRatings, Bankrate, and CJ at $50-$200+ per approval.

So how do you monetize content about these airlines? That's what the rest of this guide covers — starting with the highest-paying tier.

Tier 1 — The Real Money

Airline Credit Card Affiliate Programs: $50-$200+ Per Approval

Here's the math that reshapes how you should think about airline content monetization. A United Vacations commission at 0.50% on a $2,186 package earns you ~$11. A single Chase United card approval through CJ or CardRatings earns $50-$200+. One card application equals 5 to 20 vacation package sales. Credit cards are often the only direct conversion path for airline content, and they dramatically outperform even the best direct airline commissions.

The strategic insight: every airline review, route comparison, or "best time to fly" article is a credit card opportunity. A reader researching Delta flights to Paris is also a prospect for the Delta SkyMiles Platinum Amex. Structure your content to address the flight question first (building trust), then present the card as the natural next step for earning miles on that route.

Tier 2 — The Rest of the Trip

Hotels, Car Hire & Insurance: Higher Commissions Than Airlines

A reader researching flights is also booking hotels, renting cars, and buying travel insurance. These adjacent products often pay better than the airline itself. Commission rates of 3-8% on hotels and car hire dwarf the 0.5-2% typical of direct airline programs, and a single article about "flights to Paris" can link to all of them.

Hotels

Your reader needs somewhere to stay at the destination. Hotel affiliate commissions run 3-7%, well above airline rates, on average baskets that often exceed $500.

Car Hire

Ground transport at the destination. Rental car programs offer 5-8% commissions — a single car booking can earn more than several airline ticket commissions combined.

Travel Insurance

Travel insurance converts well because travelers buy it close to departure — a natural decision point after booking flights. Conversion rates of 6-14% are common, far above typical affiliate program benchmarks.

Vacation Packages

Bundles mean bigger commissionable amounts. Even at low percentage rates, the high average order values drive meaningful per-sale earnings.

Tier 3 — Broadest Coverage

OTA & Aggregator Programs: Cover Every Airline

Online travel agencies work for all airlines, including the Big Four that have no direct programs. Many OTA EPCs exceed direct airline EPCs, with no per-airline approval friction. Join one OTA program and you can monetize content about any carrier.

Note that Booking.com's $5.65 EPC on CJ exceeds every direct airline program except ITA Airways. For publishers covering the Big Four US carriers, OTAs are the primary path to earning commissions on actual flight bookings. Pair OTA links with credit card CTAs for a two-revenue-stream approach on every article.

Tier 4 — Direct Airline Programs

The 10 Best Direct Airline Affiliate Programs

For publishers set on promoting airlines directly, here are the programs with real performance data. These complement the revenue tiers above — they're not the primary revenue driver for most airline content, but they add an incremental layer for carriers that have programs.

Airline Affiliate Programs: What the Data Shows

The airline affiliate vertical operates under constraints that distinguish it from most categories. Commission rates are among the lowest in affiliate marketing, typically clustering between 0.5% and 3%. This is often compounded by a "base fare only" rule, where commissions are not paid on taxes, fees, or fuel surcharges. On a $1,200 long-haul ticket, the commissionable base fare might only be $500, dropping your effective commission rate to less than 1% of the total price a customer pays.

Because of this, the most successful airline content publishers diversify their monetization. Vacation packages consistently outperform standalone flight bookings. Programs like United Vacations ($2,186 avg basket) or British Airways Holidays (2-5% commission) can deliver materially higher earnings per sale. Online travel agencies (OTAs) and aggregators like Trip.com often offer better terms and broader product ranges than direct airline programs.

Cookie duration is another critical factor. While 30 days is a common standard, several major carriers offer less. Lufthansa and Singapore Airlines both have 14-day cookies, putting pressure on affiliates to drive immediate conversions. On the other end of the spectrum, the Emirates program on the Admitad network reportedly offers a 365-day cookie, providing a massive window to capture commissions from considered purchases.

Putting It Together: Content Strategy for Airline Affiliates

The revenue stack isn't theoretical — it's a practical blueprint for every piece of airline content you publish. Here's how to layer the tiers on a single article.

"Best Flights to Paris" Article

Credit card CTA: Open with the flight research (building trust), then present the relevant airline card — "earn 3x miles on this route with the Chase Sapphire Preferred." Hotel links: "Where to stay in Paris" section with Booking.com affiliate links (4%, $5.65 EPC). Car hire: "Getting around France" sidebar with Avis or Europcar (8%). Insurance: "Do you need travel insurance for France?" with Travelex link. OTA: Link to actual flight booking via Booking.com or Priceline. Direct airline: If covering Air France or another carrier with a program, add that link too. One article, five or six revenue streams.

"Delta vs United" Comparison

Neither airline has a flight affiliate program, so the entire monetization comes from credit cards: Delta SkyMiles Amex vs Chase United Explorer. This is a natural credit card comparison article disguised as an airline comparison. Add OTA links for readers who just want to book.

Minimum Viable Monetization

At minimum, every airline content page should have three things: a credit card CTA for the relevant airline (Tier 1), a hotel link for the destination (Tier 2), and an OTA link for the flight booking itself (Tier 3). This combination works regardless of whether the airline has a direct affiliate program — which, for the Big Four US carriers, it doesn't.
