We had a similar experience when trying to obtain our flight check in for Sky Express. We clicked on the incorrect link and was taken to mytrip.com. I fee of 1€ was requested and we assumed that this was standard procedure for Sky Express only to discover 3 days later that a further 79€ had been taken from our account. We didn’t sign anything but apparently buried deep in the small print is a clause saying that if we didn’t cancel our “membership “ then the 79€ would be taken on a recurring quarterly basis. Unfortunately telephone conversations and emails failed to resolve this situation to our satisfaction. Unethical and unprofessional and possibly illegal practice in our opinion. We would never use this “service “ again….be wary what you click on,the top link may not be the one that you need.
