Travelport is estimating almost half of the world's airlines may eventually join a core component of its Merchandising Platform.
CEO and president Gordon Wilson says over 110 carriers have now signed up to the Rich Content & Branding system where they can now retail their entire product range, in a format and with functionality similar to a brand's own website.
Travelport could reach 220 out of a possible 440 airlines around the world, Wilson says.
Wilson says seven out of the top ten carriers are now on the service, with talks ongoing with two the remaining airlines, American Airlines and China Southern.
Southwest is unlikely to complete the full suite of ten, he concedes.
Wilson was speaking to Tnooz to coincide with the release of Travelport's second quarter results for 2015, reporting a raising of its forecast for the rest of 2015 to the "top-end" of its range.
Net revenue in Q2 increased by 1% to $554 million, with the first half of the year coming in at $1.126 billion (flat compared to the same six-month period in 2014).
Adjusted EBITDA narrowed slightly to $137 million from $146 million between Q2 2014 and 2015.
In terms of from where revenue is now coming, "air" still makes up the lion's share of the overall pie for Travelport although the $400 million figure for Q2 2015 was down 2% on the same period in 2014.
"Beyond Air" revenues jumped 12% to $122 million in Q2.
This segment now represents 23% of the company's overall income from activities, and Wilson says it remains on track to reach a third by 2018.
eNett, the virtual payment technology provider, made up $20 million of the $122 million "Beyond Air" on the back of growth of 27% year-on-year in Q2.
The addition of a quarter of the industry's airlines to the Rich Content & Branding service will soon start to having a meaningful impact on the company's revenues, Wilson says, though not necessarily through increased levels of distribution to third parties but from the fees carriers pay to be included on it.
Wilson highlights how all the carriers in the Lufthansa Group's network, including the mothership brand alongside Swiss International Air Lines, Austrian Airlines, Germanwings, are now using a system that replicates the functionality from Lufthansa from its own website - a reminder to the carrier that the tax it plans to introduce a tax on all bookings by intermediaries from September has not gone down very well in the world of the global distribution systems.
Wilson argues that Lufthansa may find itself with consumers, who use intermediaries, unwilling to pay the additional Euro 16 fee, especially as the carrier's actual product and parts of its network have viable competitors.
"On average the consumer probably won't eat the cost of that."
