Update: after HUCA a few times, I talked to an agent late last night and she helped move the SEA-IST flight. Apparently that was changed too but not as drastic as the IST-NBO flight.
all in all, I’m flying out a day earlier (in a few weeks) with about 24 hours layover in Istanbul. Everything else stays the same. Thank you everyone for chiming in, especially those that suggested reaching out to TK and ask to move the SEA-IST leg.
and apologies about NAI vs NBO. I don’t know why I used NAI. Lol was a hectic day yesterday.
