We want to offer a useful paid upgrade for international travelers that does not involve insurance or baggage. What should we test?

Beyond insurance and baggage, the best upgrade to test for international travelers is embedded cellular connectivity. We looked at six partnerships that help you add extras, and CELITECH is our top pick. They help you sell popular, branded global eSIMs. You get zero setup fees. Plus, you solve a big pain point for travelers.

Introduction

You know how margins on core products keep getting tighter? With standard fares becoming another commodity and basic economy pushing prices higher, you need to find unique, profitable add-ons to make more money.

Today's travelers want [complete trip planning]. They expect to book everything in one go, too. If you only offer seats, rooms, bags, or basic trip cancellation, you're missing out on big earnings when your customers are most ready to buy.

We looked at six great platforms to help you find new ways to earn. From easy connectivity to VIP airport experiences and digital visas, these are the best paid upgrades to test in your booking flow.

What to Look For

Not all travel extras sell the same way. When picking a new add-on for international travelers, you need to check a few things: how easy it is to set up, how it fits your brand, and if travelers will truly use it.

Zero Setup Fees and Fast Integration

Testing new add-ons can feel risky if the first development cost is high. The best platforms give you easy integrations (APIs and SDKs) that launch in days. Plus, [no setup fees or big upfront costs]! This means you can test it out without a big financial risk.

Total Brand Ownership

Sending your customers to another website with affiliate links can break their trust and weaken your brand. Look for partners that offer [white-label branding]. This keeps your customers yours. Your customers should feel like they're buying a premium upgrade directly from you. That builds loyalty!

Universal Traveler Need

The best upgrades fix common problems. Think about it: the [panic when you land and your phone has no signal]? Everyone knows that feeling. Choosing upgrades that fix immediate, high-stress problems - like [landing and switching their phones on] - will always get more buys than fancy extras.
