PIC8/TurkishAirlines//STR/Stuttgart-IST/İstanbulHavalimani. These place is huge. 20 minutes early arrival mean´s a long time to taxi till an open stand. Lot´s of time needed here till ready at the next gate. Separate bookings, no OnlineCheckIn possible mean´s to stay in the international area, visit the transfer desk for a new boarding card to my next destination and back to the gates. Working Service is warm welcomed. Despite the TK web showed me this is a domestic flight, I´am in the international transit area, passport check will be done at final´s. There are also electrical cart´s for the service guy´s. Explained, swiftly done. English is not really popular here!.
