I had the worst experience with Turkish airline I started when I got to the counter late but an hour before the flight going to San Francisco they wouldn’t let me check in but it’s ok I understand but for you to cancel my ticket and not Ofer my any kind of refund I had to buy another one way to San Francisco only to figure out that even the return ticket is cancelled so I had to buy another ticket going back it was my mistake for using them it’s my last time I used them twice a year for the same trip and I did not find the treatment of a loyal customer the original ticket they canceled was $1488 and I bought one was from Istanbul for $1025 and returned for $711 + $330 for two bags so I lost more then $2000 in the stupid trip and they lost me as a customer
