I booked an ANA award on Turkish TLV-IST-GRU. Was on the 5 AM TLV-IST and connecting to GRU 9:40 AM. I changed the date of the ticket, and they put the new one for 1 AM departure for TLV-IST, and I didn't realize and missed the TLV-IST flight. The 5 AM flight has seats available, and I can make the 940 connection if they put me on the 5 AM flight, but airport reps in TLV say they can't do anything because it was bought through ANA. There are no mileage seats available for the 5AM flight, so ANA is saying they can't do anything. Also, Turkish marked as no show. Is there anything that can be done? Who should I pressure?
