Seems on average TK flight (TK204) often around 2 hours+ late taking off for Istanbul. Often related to late incoming aircraft (TK203). Have flight in late March with 2 hour 50 minute connection to TLV. Am becoming increasingly worried about connection given their performance to date on this route. Is it likely that TK will adjust times of route such as earlier inbound arrival to try and improve performance? I realize this is a new route and may take some time to straighten things out, but this does not seem to be improving. Have been looking forward to flying TK on 787. Several years ago flew LAX-IST on TK 777 and was impressed but this current performance issue is concerning. Do not want to overnight in Istanbul or get into TLV in the middle of the night.
