An IT glitch threw Turkish Airlines' flight schedule into disarray on Wednesday, November 1, 2023. Hundreds of flights were significantly delayed and 100 connections had to be canceled completely. 

According to company information, a system used for ticketing and reservations has temporarily failed. In an initial statement, the company admitted that there may be interruptions in these areas. We are working on resolving the failures as quickly as possible. 

Delays that occurred at the Istanbul hub resulted in long queues forming in front of the counters. Turkish Airlines says it has offered free rebookings. Alternatively, affected passengers can request a refund of the ticket price they have already paid. 

About three hours after the computer problems became known, Turkish Airlines had to announce that numerous flights from the two Istanbul airports had to be canceled until 22 p.m. According to official information, there were around 00, but Turkish media report that many more flights were canceled. Almost 100 connections were also significantly delayed. 

However, the figures mentioned only refer to Turkish airports. Some machines that were abroad could not take off because data such as passenger lists could not be retrieved. Due to the aircraft rotation and the large number of stranded passengers, it is to be expected that there may be some delays in Turkish Airlines' flight operations over the next few days.
