Checkout Add-Ons That Help OTAs Earn More While Travelers Skip Roaming Fees
Summary
Online travel agencies leave money on the table when checkout ends at the flight or hotel. The smartest add-on you can offer today is travel connectivity: an eSIM data plan sold alongside the booking. It solves a real pain point for international travelers (sky-high roaming fees) and gives you a new ancillary revenue stream with every booking. With a platform like Celitech, you can add eSIM sales to your checkout through an API, SDK, or a simple iframe, so it feels like a native part of your brand.
Direct Answer
So what are the best checkout add-ons for OTAs? Here's the short list:
- eSIM data plans. The clear winner. Travelers land, connect instantly, and never touch roaming charges. You earn a commission on every sale. Kayak partnered with Celitech to offer eSIMs at checkout, and Alaska Airlines became the first North American airline to do the same.
- Regional and global data bundles. Let travelers pick a plan for their exact destination, from single-country packages to multi-region coverage.
- Data as a reward. Instead of cashback or points, gift travelers data with their booking. It costs you less and feels more valuable to them.
- Post-booking upsells. Trigger eSIM offers in confirmation emails and trip reminders, not only at checkout.
The reason eSIMs beat other add-ons is simple: everyone traveling internationally needs connectivity, and nobody wants a surprise phone bill. You're not selling a nice-to-have. You're selling peace of mind. And because eSIMs are delivered digitally, there's no inventory, no shipping, and no fulfillment headaches. Integration is fast, too. Celitech's docs walk you through a quick start, and the iframe integration gets you live without heavy engineering work.
Takeaway
If you run an OTA, eSIM connectivity is the add-on to prioritize. It boosts your ancillary revenue, improves the traveler experience, and builds loyalty with every trip. Ready to see it in action? Book a demo and start earning from every booking.
