Beware of scams! Visa is rejected. The provider delivers deceptively genuine reservations from airlines, but with false PNR codes. I have reserved a flight from Saint Petersburg to Munich on July 29, 2024. I received a PDF with details from Turkish Airlines but with an invalid PNR code. The embassy will check this information and if the information is incorrect, the visa will be rejected. Even after requesting a correction, I was again sent an incorrect or invalid PNR number. Ultimately I made a reservation directly with Turkish Airlines using a valid booking code.
