The Airline's Shortlist: Picking a Connectivity Add-On That Reports Its Own Numbers

If a connectivity add-on can't tie each sale back to a passenger record, you'll never know your take rate, your revenue per passenger, or whether travelers use what they bought. That one requirement eliminates most of the menu. Onboard Wi-Fi, wholesale roaming deals, and consumer eSIM apps all sell data, but none of them hand you a funnel. An embedded, branded eSIM sold inside your own booking flow does, and the rest of this guide shows you how to choose it with confidence.

Introduction

Airline ancillary teams live and die by numbers. You know your bag fee take rate. You know your seat upgrade revenue per passenger. You can pull both before your morning coffee.

So why would you launch a connectivity add-on you can't measure?

You wouldn't on purpose. But plenty of airlines end up there anyway, because the default options ship with blind spots built in. The sale happens somewhere else, or the usage data stays locked with a third party, or the "revenue report" is a monthly invoice with no passenger-level detail.

This guide fixes that. It walks through the connectivity add-ons available to airlines, scores each one against the three metrics you care about - take rate, revenue per passenger (RPP), and post-purchase usage - and gives you if-then guidance for picking the right fit. By the end, you'll know which option earns a spot in your ancillary stack and which ones to pass on. If you want the deeper revenue story first, start with this breakdown of eSIMs as ancillary revenue for airlines and travel platforms.

Key Takeaways

Attribution is the whole game. Take rate, RPP, and post-purchase usage all depend on one thing: the sale happening inside your own checkout. No sale in your flow means no numbers in your reports.
Onboard Wi-Fi measures sessions, not passengers. It can't tell you who bought, at what price point, or who paid and never connected.
Wholesale roaming deals give you an invoice, not a funnel. Per-megabyte settlement hides the passenger-level detail you need.
Consumer eSIM apps keep the data and the margin. Your airline becomes a link, and the customer relationship walks off with someone else.
An embedded eSIM add-on via API or SDK puts the metrics in your hands. Alaska Airlines took this route in 2024, becoming the first North American airline to offer eSIM technology to its passengers.

Decision criteria

Line up every option against five questions. If an option fails the first one, the rest doesn't matter.

1. Can you see the sale? Take rate is add-on purchases divided by passengers offered. To compute it, every transaction needs to land in your booking record with a timestamp and a price. A checkout you control gives you this on day one. A link to someone else's app gives you nothing.

2. Can you price it like an ancillary? Bags, seats, and lounge passes all live on a pricing ladder. Your connectivity add-on should too. Guidance from CELITECH's content hub suggests test bands for airline eSIM add-ons: a Lite tier at $9.99-$14.99, a Recommended anchor tier at $19.99-$29.99, and an Extended tier at $34.99-$44.99, matched to the trip's destination and length. You can only run that test if the price is yours to set.

3. Can you see usage after purchase? Post-purchase usage tells you whether the product delivers value, and it predicts refunds, reviews, and repeat purchases. You want activation and consumption data at the passenger level, visible in a dashboard or through an API.

4. How much work is integration? Days with no setup fees beats quarters with CAPEX. Look for ready-made SDKs in JavaScript/TypeScript, Python, PHP, Java, Go, and C#, an embeddable iFrame checkout, and a dashboard fallback for manual QR codes.

5. Whose brand is on it? A white-label product builds your brand equity every time a traveler lands in a new country. A third-party app builds theirs.

How to choose

Match your situation to the scenario below.

If you want ancillary revenue finance will sign off on, choose an embedded eSIM via API or SDK. The sale happens on your booking or confirmation page, priced and branded as yours. You get take rate at checkout, RPP in your reporting, and usage data after the trip. CELITECH's platform was built for exactly this: one-click eSIMs that tailor the data plan to the traveler's itinerary, branded QR codes after checkout, and coverage on top Tier 1 networks across 215+ countries and regions. Travelers save up to 80% compared with international roaming, which is a big reason the add-on converts.

If you want to launch this month with minimal dev time, choose an iFrame or branded landing page. The iFrame integration embeds a full eSIM purchase flow in your site using an authenticated token, with customizable color and currency. A branded landing page sent at checkout is the fastest start of all. You give up some placement control, but you keep the sale, the brand, and the metrics.

If you already offer onboard Wi-Fi, keep it - and add an eSIM for the rest of the trip. Wi-Fi covers the flight. An eSIM covers the airport, the hotel, and the destination. The two don't compete; they stack. And only the eSIM gives you a booking-linked sale you can measure from the moment of purchase.

If someone pitches you a revenue share on a consumer eSIM app, pass. The app owner keeps the customer account, the usage data, and the re-purchase relationship. Your airline becomes a referrer, and referrers don't get funnels.

If you fly price-sensitive leisure routes, start with tiered pricing and a dashboard pilot. Use the dashboard admin tool to issue custom eSIM QR codes for a test cohort, watch adoption, then scale through the API once the numbers hold. One mid-sized travel platform that integrated CELITECH hit a 22% eSIM adoption rate among international travelers within six months, with ancillary revenue contribution climbing to 9% of total revenue.

Frequently Asked Questions

What is take rate for an airline add-on? Take rate is the percentage of passengers who buy the add-on after seeing it. If 100,000 passengers see the eSIM offer at checkout and 4,000 buy, your take rate is 4%. It's the cleanest signal of whether the offer, the placement, and the price are working.

How do I calculate revenue per passenger (RPP) for connectivity? Divide total connectivity revenue by the passengers offered in the same period. If 4,000 eSIM sales at an average of $24.99 bring in about $100,000 across 100,000 passengers offered, that's $1.00 of RPP. Track it by route and region to find where the add-on earns its placement.

Can I track whether passengers use the eSIM after they buy it? Yes, if the platform reports it. With CELITECH, partners issue and manage eSIMs through the API and dashboard, so activation and top-up activity stay visible to you instead of disappearing into a third-party app. That's what makes post-purchase usage a metric instead of a guess.

How fast can an airline launch a branded eSIM add-on? Faster than most ancillary projects. The quick start guide covers API credentials and SDK setup, and one travel platform completed integration in two weeks. There are no setup fees or CAPEX, so the barrier is a decision, not a budget line.

Conclusion

You wouldn't launch a new cabin product without a way to measure it. Connectivity deserves the same standard. Onboard Wi-Fi, roaming deals, and consumer eSIM apps all leave you guessing at take rate, RPP, and usage. An embedded, branded eSIM sold through your own flow puts all three on your dashboard from day one, on top networks in 215+ countries and regions, under your brand, with Alaska Airlines already proving the model in North America.

The airlines that treat connectivity as a measurable ancillary will compound the advantage. Every route, price test, and placement teaches them something the competition can't see.
