Error when changing TK flights online?
 

Trying to change an existing TK business class flight and am receiving the below error ... has anyone obtained tips on how to tackle it? Change is regarding the city I depart Europe from (e.g., instead of CDG --> IST --> SFO, I'm looking at FRA --> IST --> SFO) ... same class of service, date of flight, etc.

Appreciate any guidance you may have ... hoping that I don't have to call-in to process the change!

As much as you don’t want, I think the solution is to call TK call center but first try to make the changes on TK app.

Just an update - I tried to make the changes online again today, and by some miracle, it worked! Perhaps good fortune ... will definitely give the mobile app or calling a try next time (particularly if I'm in a crunch).
