Forget Donald Trump versus incredulous Americans who didn't vote for him - it's getting really ugly in the very public battle between Ryanair and eDreams.
The axing of the airline's contract with Momondo this week has triggered a verbal salvo from Ryanair's most hated online travel agency, eDreams.
The European low-cost carrier says Momondo is displaying its fares and then linking to online travel agencies such as Opodo (part of the eDreams Odigeo stable), which it is in dispute with over screenscraping and alleged false advertising.
Travel search site Momondo was one of a number of sites – along with Skyscanner and Dohop – that was given a non-exclusive license to display Ryanair’s tickets for price comparison purposes.
Showing Ryanair’s fares from Opodo as well as those direct from the airline has led to it ripping up the agreement.
eDreams Odigeo has weighed in on the latest episode in the saga, claiming the airline is "trying desperately, but failing, to stand in the way of the millions of people using online travel agent sites like ours, to get the best deal and the most convenient combination of flights possible".
An official adds:
"Ryanair are threatened by the fact that close to half of our customers book a combination of flights which cannot be booked on any single airline website."
The company says Ryanair is using "bullying behaviour" in a bid to remove deals via online travel agencies from comparison sites, and therefore travellers are the ones "losing out".
Countering Ryanair's continued criticism of eDreams Odigeo for both misrepresenting its brand and not providing customers with the best information about a booking, the official says:
"We offer customers all the information needed to book their flight and make sure they know of any changes to their travel or check-in, through our free mobile app – it is misleading to suggest otherwise."
eDreams Odigeo claims the airline will be on the end of a Civil Aviation Authority investigation "soon", as well as a class action from 5,000 travellers into alleged unfair charges.
Ryanair, the official says, "would be wise to spend their time on improving the way they treat their own customers, instead of standing in the way of people using our service to get the best deal and the most convenient combination of flights".
This anticipted action follows a probe by the CAA into eDreams earlier this year.
In response, a Ryanair official says:
"Ryanair has no issue with OTAs who display Ryanair’s fares in a transparent manner.
"It’s important to note that Ryanair has no commercial agreement whatsoever with eDreams or Opodo, who continue to engage in unauthorised screenscraping and sell on Ryanair’s low fares. We again urge customers to book directly on the Ryanair.com website."
