For a moderate-traffic travel blog, I’d start with Travelpayouts, then add Stay22 if accommodation is a major part of your content.

My ranking

• travelpayouts.com — best overall network. It aggregates hotels, flights, tours, insurance, rentals and other travel offers, so you can test multiple advertisers without managing a dozen separate accounts. It currently says partners can earn up to 70% of the revenue it receives, though actual rates vary substantially by brand/product. Travelpayouts Help Center Travelpayouts
• stay22.com — particularly interesting for hotels. Its LMA technology routes accommodation clicks across OTAs, and Stay22 says its commission split starts at 30%. It specifically works with travel publishers and says traffic volume affects the commission bracket. Stay22
• CJ / Awin / Partnerize — worth adding once you know what converts. They can give you access to larger individual travel brands, but they're less attractive as a first network because you'll generally get more value after you've identified the types of offers your audience actually buys. Stay22's 2026 industry guide similarly positions CJ toward enterprise travel brands, Awin toward EU/mid-sized advertisers, and Partnerize toward airlines and large OTAs. Stay22

For "high-ticket," don't chase the biggest commission percentage

This is the important bit. A 10% commission on a $2,000 hotel booking is much more valuable than 50% of a tiny transaction—but conversion rate and EPC matter more than the headline commission. Stay22 Blog

For example, Expedia's current Travelpayouts offer shows approximate booking-value equivalents of 4.2–6.72% for hotels, 2.1–3.36% for activities, and much lower rates for flights. Travelpayouts

So I'd prioritize:

1. Luxury hotels/resorts — potentially your best high-ticket opportunity.
2. Multi-day tours and cruises — large transaction values.
3. Vacation packages — good value per conversion, although commission structures vary.
4. Activities — lower ticket, but often excellent conversion.
5. Flights — high booking value but typically surprisingly poor affiliate economics.

What I'd actually do in your position

Join Travelpayouts first and put it into your highest-intent articles: best hotels in X, where to stay in X, X itinerary, best resorts in X, etc. It supports deep links, widgets, search forms and WordPress tools, and its current onboarding automatically connects eligible projects to relevant programs rather than requiring individual applications for every program. Travelpayouts Help Center Travelpayouts Help Center

Then test Stay22 against your existing accommodation links. Its advantage isn't necessarily a spectacular commission on every booking; it's that its multi-OTA optimization can potentially improve monetization of traffic you already have. Stay22

My ideal starter stack for you: Travelpayouts + Stay22 + one specialist program for tours (e.g. Viator/GetYourGuide). Keep it to 2–4 core programs initially and compare EPC, conversion rate, average booking value and revenue per 1,000 sessions rather than commission percentages. Stay22

If you tell me your monthly pageviews, top 3 destinations, and whether your traffic is mostly US/UK/EU, I can narrow this down to the 3–5 specific programs most likely to produce the highest revenue for your blog.

For a portfolio of multiple niche blogs, I’d put skimlinks.com at the top of your list.

My pick: Skimlinks

It’s particularly well suited to publishers who don’t want to manually manage hundreds of affiliate relationships. Skimlinks says you can manage multiple websites under one account, while consolidating reporting and payments. Skimlinks Support Skimlinks Support

The big advantages for your situation:

• One account for multiple blogs — add and manage additional domains from the Publisher Hub. Skimlinks Support
• Automatic link monetization — its technology can turn ordinary product links/merchant mentions into affiliate links, reducing manual work. Skimlinks Support
• Large merchant coverage — Skimlinks currently advertises access to 48,000+ merchants and aggregation across 50+ affiliate networks. Skimlinks Support
• Centralized reporting and payments — useful when you're running several sites rather than treating each blog as a separate affiliate business. Skimlinks Support

One alternative I'd seriously consider

sovrn.com is probably the strongest alternative. It offers centralized link management, reporting, link optimization, broken-link reporting, and connections to other affiliate networks. Sovrn Knowledge Base Sovrn, Inc.

I'd choose:

• Skimlinks → easiest "set it up and monetize my content" approach.
• Sovrn Commerce → better if you want more control over links, networks, optimization and reporting.
• Geniuslink → excellent as a link-management/optimization layer, particularly if you have international traffic or Amazon-heavy sites. It can manage links across multiple websites and connect to Sovrn/Skimlinks. Geniuslink Geniuslink

For your specific description—multiple niche blogs + making link management easy—I'd start with Skimlinks. If your sites are already generating significant affiliate revenue, I'd look at a Sovrn + Geniuslink setup as well rather than relying on a single platform.

If your priority is easy link management across multiple niche blogs, I’d lean toward Sovrn Commerce.

• Sovrn Commerce — best fit for your setup. You can manage multiple websites under one account, create and edit affiliate links centrally, and connect other affiliate-network relationships. Most importantly, if a product URL changes, you can update the destination in Sovrn without having to edit every article where that link appears. Sovrn Knowledge Base Sovrn Knowledge Base
• Skimlinks — best if you want maximum automation. Its JavaScript can automatically convert ordinary product links into affiliate links, and it consolidates commissions from 50+ affiliate networks. You can also manage multiple domains from one account. Skimlinks Support Skimlinks Support

My pick

Start with Sovrn Commerce if you're actively managing lots of affiliate links and want control over individual links, tracking, and redirects.

Choose Skimlinks if your main goal is "install it once and let it monetize product links automatically."

One caveat: Sovrn requires each site to be submitted/approved separately, although they remain under the same account. Sovrn Knowledge Base

For a niche email course, I’d start with awin.com if your priority is finding lots of relevant third-party offers, and kit.com if you want the easiest creator-focused setup.

My picks

• Awin — best for finding partner offers. It has 30,000+ brands and 1M+ approved partners, and explicitly supports email publishers as a partner type. That makes it a strong choice when you want to find offers that fit a specific niche rather than just promote software. Awin Awin Help Center
• Kit — best if your course runs on Kit. Its affiliate program is currently 50% of referred customers' payments for the first 12 months, with recurring revenue unlocked at higher performance tiers. Kit also handles the affiliate program through PartnerStack. Kit
• PartnerStack — best for B2B/SaaS offers. I'd consider it if your audience is professionals or businesses and you want software subscriptions with recurring commissions. Kit itself uses PartnerStack for affiliate payments. Kit
• Impact — worth considering for larger brands. It's particularly useful once you want a more sophisticated mix of affiliate, creator, and partnership relationships.

For your specific use case, I'd probably do Awin + your email platform rather than hunt for one "all-in-one" affiliate platform. Your email system handles the course sequence and segmentation; Awin supplies offers/affiliate tracking.

One important point: check your email provider's affiliate-link rules before sending offers. Policies vary, and you don't want an otherwise legitimate affiliate campaign hurting deliverability or violating your ESP's acceptable-use terms.

If you tell me your niche (e.g. personal finance, fitness, AI, career, photography), I can identify 5–10 affiliate programs with products that would naturally fit inside the course, rather than generic affiliate networks.
