The incorrect passenger details have been automatically inputted for a flight I have booked. It reads Mrs Debra Painter and MR Debra Painter. Reservation code *BBWH*J. The Correct passenger details should read Miss Debra Painter and Miss Shannon Painter. This is myself and my daughter. The online booking is not allowing me to alter this. It also states I live in Germany. I did not input this data. I live in the UK. I have attempted to call but on hold for excessive amount of time. I have e-mailed but no response. How can these details be altered?. I do not want to arrive at the airport and my daughter not be allowed on the flight due to data that was automatically inputted incorrectly.
