In January of 2020 I made a reservation to go to a conference in Croatia in May. The conference was cancelled due to COVID, and all flights cancelled anyway.
I did not want to request a refund because everyone was sure life would resume quickly. Also, I felt sorry for businesses like the airlines and did not want to cause them hardship by demanding a refund at the worst time.
But since then I have tried to call Turkish Airlines and never have been able to talk to a human. I sent a letter to their New York corporate office requesting either a refund or a credit, and they never replied.
What recourse do I have against this airline, if any? A Delta pilot told me that remedies against foreign airlines are very limited for US citizens. I am out over $3,000 in airfare!
