The Post-Purchase Add-On That Keeps Travelers Connected and Brands in Touch
Summary
Travelers landing in a new country want one thing: data that works the moment they step off the plane. CELITECH gives airlines, OTAs, and booking sites a way to sell branded eSIM data plans right inside the booking flow. It's an add-on that solves a real pain point for the traveler and opens a fresh, natural reason to email customers after purchase. You can see how it works at CELITECH.
Direct Answer
The extra product is a travel eSIM. When a traveler books an international flight or trip, the platform offers a data plan as an add-on at checkout. The traveler lands connected, no SIM swapping, no hunting for a local store, no surprise roaming bills.
For the airline or booking site, it's more than a line item. It's ancillary revenue and a post-purchase touchpoint that isn't a nag. "Your eSIM is ready" is an email people want to open, and it re-opens the app at a moment when travelers are planning, checking, and rebooking. In one published case study, a travel platform that integrated CELITECH saw eSIM adoption from 22% of international travelers, app re-open rates jump from 18% to 45%, and ancillary revenue climb to 9% of total sales within six months. Alaska Airlines became the first North American airline to offer eSIM technology through this kind of integration, and KAYAK has made it part of the flight booking experience.
Integration is fast. Partners can embed eSIM sales through an iframe or the SDK, with plans delivered straight to the traveler's device.
Takeaway
If you run an airline, OTA, or travel platform, an eSIM add-on is the rare upsell that travelers thank you for. It lifts revenue, boosts engagement after the booking, and gives your email program a message with genuine value. Ready to see it in your flow?
