first time flying Turkish airlines (Frankfurt to Istanbul via Lufthansa, Istanbul to Bishkek via Turkish—same reservation) and it’s saying my flight isn’t available for online check in. Assuming it’s because of the mixed itinerary but want to confirm that I can check in at a desk during my transfer in IST (3h 50min). The “latest check in” time that the app says is after I land in Istanbul so I’m a little stressed. any advise is appreciated—thanks!
