I'm a ticket sales agent in Uzbekistan. I issued an airticket for a Uzbekistani passenger flying from Tashkent to Rio de Janeiro and back during Olympic games 2016. Immigration services in Rio refused the passenger entry into Brasil due to the absence of a visa or Olympic accreditation.
So my question is, who is responsible that this passenger was boarded for the flight and traveled from Tashkent to Rio?
In fact, when passenger asked me to issue a ticket for him, he told that he was going to fly with Olympic team of Uzbekistan and no visa required for the supporters of National team. And also, it was announced by Brazilian Government that no visa during Olympic Games 2016 in Rio.
The problem is that the passenger wants me to make him a full refund of ticket, that is 953 euros and plus 500 euros for other expenses... Besides, I was fined for about 409 euros, that is one way fare of ticket by Uzbekistan Airways for ticket issuing with no visa. So it becomes that I'm the only responsible that this passenger flew to Rio and was deported. Please give your suggestions, ways to find documents in the net(IATA, ICAO) proving that passenger visa documents should be checked by airport agents before boarding the flight.
many thanks for your opinion.
