I have not heard of people getting bumped and I'll keep that in mind. I avoid this route due to aircraft and timing, I'd rather get to DXB first and get on TK flight (always widebodies) so I can have full night of sleep before coming to IST.

Seriously, IST-MCT is way underserved and TK has monopoly here. WY should send their own metals, rather than codesharing with TK, just 3 weekly flights arriving and leaving out of IST during the middle of the day even with 737 will help. Perhaps re-allocate planes from CAI route to IST on certain days, where IST can not be any worse than CAI (both yields and load factors).

Yes I have been griping about the recent changes in J on WY A330, but for any market, 2 options is always > 1 option.
