Airlines are structurally better placed to sell travel connectivity than almost anyone else, and most do not sell it at all. You know the destination, the dates and the passenger before they have thought about mobile data. You already run an ancillary business with the commercial and technical machinery in place. And you own the moments in the journey where the need becomes obvious.
This is a practical view of how connectivity works as an airline ancillary: which touchpoints convert, the commercial models available, the design constraint that determines whether it works, and where these programmes usually stall internally.
Why airlines are unusually well placed
- You know the destination, the dates and the passenger before they think about connectivity.
- You already sell ancillaries, so the commercial machinery exists.
- Long-haul and connecting passengers are the segments most likely to buy.
- Arrival is the highest-intent moment in travel, and you own it.
- The constraint is usually internal: which team owns it, and where it sits in the flow.
The commercial case
Two data points frame the opportunity. Kaleido Intelligence found 89% of travellers would prefer to buy connectivity from a provider they already have a relationship with, against 60% from an unfamiliar specialist. And GSMA research found 51% of eSIM users first tried the technology while travelling abroad.

An airline sits on the right side of both numbers. The passenger already trusts you enough to fly with you, and you are present at the moment the need arises. That combination is what independent eSIM brands spend heavily to approximate and never fully achieve.
Average traveller spend per trip, 2026
Source: Kaleido Intelligence traveller survey, 2026. Spend per traveller is rising, which is what makes connectivity viable as an ancillary rather than a giveaway.
The pricing environment is also favourable. Average travel eSIM spend per trip rose 133% year on year to around $28 in 2026, while roaming spend fell 9% to around $42. Passengers are trading up to larger allowances rather than hunting for the cheapest option, which means connectivity can carry a real ancillary margin instead of being priced as a token add-on.
Where in the journey it converts
Placement matters more than pricing. The booking flow is the obvious candidate and one of the weaker ones, because a passenger comparing fares is not yet thinking about logistics.
| Touchpoint | Passenger mindset | Fit | Notes |
|---|---|---|---|
| Booking flow | Comparing price, not planning logistics | Moderate | Competes with seats, bags and insurance for attention |
| Manage booking | Actively preparing for the trip | Strong | Passengers return here voluntarily, often more than once |
| Check-in | Trip is imminent and real | Strong | High traffic, and the passenger is already transacting |
| Pre-departure email | Packing and preparing | Very strong | Low effort if the comms already exist |
| In-flight, via app or IFE | Thinking about arrival | Strong but constrained | Needs offline-capable purchase or onboard connectivity |
| On arrival push | Highest intent of all | Excellent | Requires connectivity to receive it, which is the paradox |
Relative fit reflects how close each moment sits to the point of need. Test against your own conversion data.
Manage booking and check-in are the practical starting points. Both have substantial existing traffic, both involve a passenger who is actively preparing rather than shopping, and both already carry ancillary offers, so the commercial and technical patterns exist.
Commercial models
Connectivity does not have to be a paid ancillary, and for some carriers it works better as something else.
| Model | What the passenger sees | Revenue effect | Complexity |
|---|---|---|---|
| Paid ancillary | A data plan offered alongside bags and seats | Direct ancillary margin | Moderate |
| Bundled in fare family | Included in premium or flex fares | Indirect; supports fare mix and upsell | Moderate |
| Loyalty redemption | Buy with points, or earn points on purchase | Drives programme engagement | Higher; loyalty integration |
| Included for premium cabins | Arrival connectivity as a cabin benefit | Differentiation rather than revenue | Low; small volumes, high perceived value |
| Disruption recovery | Data issued automatically when a flight is delayed or diverted | Cost, but a strong service recovery tool | Higher; needs operational triggers |
The disruption recovery model is worth particular attention. Issuing data automatically to passengers on a delayed or diverted flight costs relatively little and addresses the exact moment when passengers most need to contact family, rebook onward travel or reach their hotel. It is a service recovery tool that happens to use the same infrastructure as the revenue product, and it is considerably cheaper than most goodwill gestures.
Designing the passenger experience
What makes it convert
- Destination and dates pre-filled from the booking
- Validity matched to the itinerary, not a generic 30 days
- Regional plans offered on connecting or multi-stop itineraries
- Device compatibility checked before payment
- Install prompted before departure, not on arrival
- Three plan sizes at most
What breaks it
- Expecting passengers to install after landing with no data
- A generic country dropdown when you already know the route
- Validity that starts at purchase rather than at activation
- No support channel that works on airport or hotel wifi
- Selling to devices that cannot take an eSIM
- Burying the QR code in an email the passenger did not keep
The item that matters most on the left is pre-filling destination and dates. You hold that information already. Presenting a passenger with a country dropdown when their boarding pass says where they are going reintroduces exactly the friction that makes standalone eSIM stores difficult, and it is entirely avoidable.
On the right, validity behaviour causes more complaints than anything else. A plan whose validity starts at purchase rather than at first connection will expire for any passenger who buys at booking and travels weeks later. Confirm how your provider handles this before launch.
How to run the programme
Decide which team owns it
Connectivity sits awkwardly between ancillary revenue, digital, loyalty and IT. Airline projects in this category stall on ownership far more often than on technology. Name the owner before scoping anything.
Start where you already have a transaction
Manage booking, check-in or the pre-departure email. All three have existing traffic and existing commercial machinery, which means you can test attach rates without touching the booking engine.
Prioritise long-haul and connecting routes
Long-haul passengers are around 2.5 times more likely to buy a travel eSIM and multi-country travellers around 1.5 times more likely. Launching across the whole network at once dilutes the result and makes the data harder to read.
Solve installation before departure
The critical design constraint is that a passenger who has landed has no data with which to install anything. Prompt installation at check-in or in the pre-departure email, and confirm it before boarding wherever possible.
Get route-specific wholesale rates
You know exactly where your passengers go. Rates vary substantially by country, so ask for pricing on your actual destination mix rather than a generic global card.
Measure attach rate by route, not network-wide
Aggregate attach rate hides everything useful. A long-haul route and a short domestic-adjacent hop will behave completely differently, and the average tells you nothing about either.
Step one is not a formality. Connectivity crosses ancillary revenue, digital product, loyalty and IT, and airline programmes in this category stall on internal ownership far more often than on integration difficulty. A named owner with a route-level target moves faster than a cross-functional committee with a network-wide one.
