Hello, I am writing to make a claim because I was charged for a suitcase that I had previously paid for when I booked the flight in question. I booked the Prague-Malaga flight by Edreams for my partner and me, which included 2 suitcases and 2 hand luggage, both for the outward and return. When we went to Prague with Rayanair there was no problem, but when we went to take the return flight with the Smartwings company, being at the boarding gate, they told us in a very rude way that one of the suitcases had to be checked in and in a threatening tone they said that or else we would not take the flight. At all times we informed the staff that in the Smartwings application it appeared to us that there was an error in the communication of the luggage, so that they could give us some solution, but they refused to listen to us. In this same situation, several people were also seen at that time. We had to pay €60 and they also withheld my partner's ID throughout this process without wanting to return it to him, thus illegally and without consenting his personal data, since when we were sitting on the plane, a person from the crew approached with a list in hand asking him if he was indeed that person knowing his name and surname without us giving any consent in this regard. For all this, we claim the full amount that we had to pay for the suitcases in addition to compensation in some way for the mistreatment and management received by the Smartwings staff. We attach all the data of said flight.
