There is a government investigation proposed into the whole aspect of credit card charges for making bookings in many industries. It is proposed that the charge should reflect the charge made by the CC companies to the provider, and not be a source of extra randomly decided profiteering. It seems this scope of customer rip off could be widened.
Add to this little story the one about RYR refusing to accept a boarding card PDF on a smart phone; unlike other customer orientated market leading airlines who encourage such an environmentally friendly procedure.
