My flight from Stansted to Istanbul was delayed for no good reason and with no explanation from the crew at the airport and inside the plane. The crew inside reassured me I would not miss my connection to Tbilisi. However, we arrived about 20-30 minutes late and upon arrival, airport staff told me to go pick up my luggage (which took 1 hour to turn up) and head to Turkish Airlines' hotel desk. They put me up in a hotel and told me they'd rebooked on the same flight... 24 hours later! I arrived at my destination 24 hours late and Turkish Airlines are now denying me compensation on the basis that the delay was beyond their control - they are unsurprisingly doing everything they can to avoid providing me with evidence of that.
It's worth noting the exact same thing happened on my way back though that time, I ended up spending 12 hours in the airport as they didn't offer me a hotel room. Once again, they denied me compensation on the basis that the delay was beyond their control and continue ignoring my requests for evidence.
Their customer service team is helpless and doing everything they can to avoid providing me with the information I requested.
They are the most chaotic and unhelpful airline I've ever had to deal with and I do not recommend flying with them.
I went to Tbilisi to attend a conference and several people who flew with Turkish Airlines faced similar issues.
