Key factors for increasing revenue in an airline e-commerce site

Introduction

Travelers rarely buy on their first visit. They compare options and return several times before deciding.

Getting started with an airline's e-commerce strategy can feel overwhelming. But it's essentially a structured set of levers that serve one objective: revenue generation.

Three main drivers: web traffic, conversion, and average PNR.

Treating revenue as the product of exactly these three levers (traffic × conversion × average PNR) is useful precisely because it forces every initiative to declare which lever it's meant to move. A redesign that doesn't clearly improve traffic quality, conversion, or average PNR value is, by definition, not a revenue initiative — however good it looks.

1. Web Traffic

This measures both the volume and quality of visitors. Achieving the lowest possible acquisition cost is critical.

Key actions: obtain user permission for personalization, segment audiences, generate valuable content, and personalize offers.

Airlines benefit uniquely from metasearch engines: Kayak, Skyscanner, Google Flights, Dohop.

Quality matters as much as volume: a spike in traffic from a broad-match paid campaign that isn't route- or date-relevant will show up as more visits and a worse conversion rate at the same time, which can mislead teams into 'fixing' a funnel that was never broken — the traffic mix was.

2. Conversion Rate and Look to Book

Conversion rate measures the percentage of sessions resulting in a purchase. Focus on Search Intention and Look to Book.

Optimizing the search experience and simplifying the booking journey significantly boosts conversion.

Look to Book — the ratio of searches to actual bookings — is particularly useful because it's largely insulated from traffic-quality noise: a visitor who searches specific dates and a specific route has already shown real intent, so a poor Look to Book ratio points squarely at the booking flow itself, not at acquisition.

3. Average PNR

PNR average reflects revenue per booking. Key elements: average seat revenue (fare + ancillary, 10-40%) and seats per PNR.

By increasing both average fare and ancillary revenue while maximizing PNR occupancy, airlines can substantially raise total revenue.

The two components pull in different directions if managed carelessly: pushing ancillary attach rate too aggressively at checkout can suppress conversion, which lowers total PNR volume even as average PNR value rises. The metric that matters for the business is total revenue, not average PNR in isolation — so ancillary strategy needs to be tested against overall conversion, not just against attach rate.

Conclusion

Drive qualified traffic at the lowest cost. Optimize the conversion funnel. Increase average PNR through strategic upselling.

These three levers form the foundation for sustainable revenue growth.

In our experience running these audits, the lever with the most unclaimed value is usually conversion, not traffic or PNR — because it's the one most teams have never measured step-by-step. Traffic has a media budget and a clear owner; PNR has a revenue management team. Conversion often has neither, and quietly leaks more revenue than either of the other two.
