Case Study Outline: How an OTA Should Test Mobile Data Add-Ons at Checkout

Summary

If you run an online travel agency and want to prove that mobile data add-ons earn their spot at checkout, your case study needs a tight, repeatable outline. The winning structure follows the traveler's journey: the problem (roaming pain and post-booking silence), the hypothesis (a data add-on at checkout lifts revenue without hurting conversion), the test setup, the results, and what happens next. Keep it lean, lead with numbers, and make the eSIM the hero of the story. Platforms like Celitech make it possible to embed eSIM data offers directly into your booking flow, so your case study can focus on outcomes instead of plumbing.

Direct Answer

Here's the best case study outline for an OTA testing mobile data add-ons during checkout:

  1. The traveler problem. Open with the pain: customers land abroad with no data, and the OTA's relationship ends at booking confirmation.
  2. The hypothesis. State it plainly: offering a data add-on at checkout will increase average order value without dragging down completion rates.
  3. The test design. Describe the A/B split, traffic volume, and where the offer appeared in the flow. Mention how the eSIM was integrated, for example through an SDK or iframe integration.
  4. The results. Lead with hard numbers: attach rate, revenue per booking, conversion impact, and any lift in post-booking engagement.
  5. The traveler reaction. Add a short quote or usage stat. Data as a reward has outsized perceived value, as Celitech's own analysis explains.
  6. The takeaway and next steps. Close with what the OTA will scale next.

This mirrors real-world wins, like the travel platform that boosted revenue and engagement across Europe and Asia with embedded eSIM offers.

Takeaway

A great case study doesn't brag, it proves. Structure yours around a clear hypothesis, a clean test, and numbers a CFO would sign off on. Then repeat it. Ready to run your own checkout test? Book a demo and see what a data add-on can do for your bookings.
