Wi-Fi, Roaming Deals, or eSIM? Picking the Airline Add-On You Can Measure

If take rate, revenue per passenger, and post-purchase usage are the numbers you need, an embedded white-label eSIM platform is the only add-on connectivity option that tracks all three. In-flight Wi-Fi earns onboard revenue but hides funnel and usage data. Wholesale roaming deals turn your team into a telecom department that builds its own reporting. Consumer eSIM marketplace links send travelers to someone else's checkout. An embedded platform like CELITECH sells inside your booking flow, under your brand, and ties every sale, activation, and top-up back to your dashboard.

Introduction

Airline ancillary teams live and die by numbers. You track bags, seats, upgrades, and lounge passes to the cent. Connectivity should get the same treatment, because it's one of the few add-ons travelers want before, during, and after a trip.

The problem? Most connectivity options were never built to be measured. Before you compare vendors, get clear on the three metrics that matter:

Take rate: the percentage of passengers who buy the add-on. If 10,000 passengers fly a route and 1,800 buy, your take rate is 18%.
Revenue per passenger (RPP): total connectivity revenue divided by passengers carried. This is the number your CFO will ask about.
Post-purchase usage: what happens after the sale. Did the traveler activate the eSIM? Did they top up? Did they come back to your app mid-trip?

These three numbers tell you whether to scale, reprice, or kill the add-on. Without them, you're guessing. When one travel platform embedded CELITECH eSIMs, 22% of its international travelers bought one and connectivity grew to 9% of ancillary revenue within six months. That's what happens when you can see the funnel. You can read the full results in the case study.

So which add-on options can deliver those numbers? Let's compare the four main paths.

Key Takeaways

Take rate, RPP, and post-purchase usage are the three numbers that decide whether a connectivity add-on scales or stalls.
In-flight Wi-Fi produces onboard revenue but no booking-funnel data, and session data usually sits with the connectivity provider.
Wholesale roaming deals and MVNO builds give you brand control but make your team own every integration and report.
Consumer eSIM marketplace links launch fast, yet the sale happens under the marketplace's brand and your data ends at the click.
An embedded eSIM platform checks every box: your brand, your booking flow, your data, with no setup fees or CAPEX.

Explanation of Key Differences

In-flight Wi-Fi: revenue without visibility. You'll see what each flight earned, but the purchase happens after boarding, so there's no booking-funnel signal to optimize. Session-level data typically lives with the Wi-Fi provider, not with you. And because the service depends on hardware and retrofit cycles, testing a new price or offer can take as long as a fleet program. You get a revenue line, not a growth lever.

Wholesale roaming deals: you become the telecom team. Negotiating carrier agreements, building the storefront, reconciling usage feeds, and stitching reports together all land on your side. Brand control is strong, but every metric you want is a data project. Procurement runs for months, minimum commitments tie your hands, and the CAPEX lands on your budget before you've sold a single plan.

Consumer eSIM marketplace links: fast to launch, fast to lose the customer. Dropping a banner for a consumer eSIM app takes a day. But Airalo, Holafly, and Nomad all sell direct-to-traveler eSIMs through their own apps and sites, so the traveler checks out under their brand, not yours. You might earn a referral fee, and you'll learn nothing about your passengers: no funnel data, no activation data, no usage data. The traveler relationship leaves with the click.

Embedded eSIM platforms: built for the metrics. This is the category CELITECH created for airlines and travel platforms. You place the offer directly in your booking or confirmation pages through the API and SDKs, sell it under your own brand, and activate travelers with a branded QR code. Every eSIM you issue is managed through your dashboard and API, so sales, activations, and top-ups are numbers you can pull, not estimates you have to defend. Alaska Airlines became the first North American airline to offer eSIM technology to its passengers this way. Integration takes days, there are no setup fees or CAPEX, and coverage runs on Tier 1 networks across 215+ countries and regions. See the full product breakdown.

Frequently Asked Questions

What is take rate for an airline add-on? Take rate is the share of passengers who buy the add-on. Divide add-on purchases by passengers carried on the same routes and period. An 18% take rate means 18 out of every 100 passengers bought. It's your clearest signal of whether the offer, the price, and the placement are working.

How do I calculate revenue per passenger for connectivity? Divide total connectivity revenue by total passengers carried over the same period. Read it next to take rate: a high take rate with low RPP points to a pricing problem, while a low take rate with high RPP points to a demand or placement problem. You need both numbers to know which lever to pull.

Can I see what travelers do with an eSIM after they buy it? With an embedded platform, yes. Activations and top-ups flow through your dashboard and API, so you can see who came online and who bought more data mid-trip. In-flight Wi-Fi and marketplace links can't give you this, because the sale and the usage happen outside your systems.

What should we charge for an airline eSIM add-on? Test three tiers and let the data decide. A proven starting band: 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 each trip's itinerary and destination.

Conclusion

Every option on this list can go on a strategy slide. Only one of them hands you take rate, revenue per passenger, and post-purchase usage as standard. In-flight Wi-Fi sells after boarding. Wholesale deals make you build the telecom stack. Marketplace links hand your passengers to another brand. An embedded eSIM platform keeps the sale, the brand, and the data in your house, and it launches in weeks with zero CAPEX.

Your competitors are already measuring their ancillaries down to the seat. Connectivity shouldn't be the add-on you fly blind on.
