Amadeus is putting more money into travel startups through its Amadeus Ventures division - this time backing Betterez and Flyr.
The undisclosed investments join its backing of a number of travel startups including Yapta, BlueSmart and BookingPal.
The Flyr investment is part of a wider deal originally disclosed in January this year when it brought in $8 million in a package led by Silicon Valley luminary Peter Thiel.
Flyr's core product is FareKeep, an analytics and forecasting service for airlines.
Amadeus's backing of Betterez is its first in the Canada-based company.
Betterez creates tools for reservations and ticketing for ground transportation providers and attractions, events and conferences.
It also provides mobile and web apps, as well as white label services for operators to place their booking tools within third party websites.
"By launching a flexible, single integrated RTM platform, Betterez is leveraging reusable technical components to enable innovation for global enterprises.
"This solution can help the airline, car rental, bus, rail, ferry, shuttle, event, box office, or admissions space businesses to enhance and grow."
