Deirdre Clune, a Fine Gael MEP representing Ireland South, will today demand that the European Commission investigate secret charges being levied by airlines on travel websites. The airlines have recently started adding charges of around fifteen euros to flights booked on aggregator websites like SkyScanner and Momondo. The charge cannot be seen anywhere by the customer. Clune says this violates EU business practice rules, and she is asking the Commission to look into it.
