How to upgrade both legs of economy tickets?
Just bought 2 economy tickets (KTM-IST-SFO) for Thursday. Turkish Airlines is only showing offer to upgrade KTM-IST leg (both for 50k miles total). Is there a way to upgrade IST-SFO as well? Also, what happens to luggage allowance if I only upgraded KTM-IST ? Is it 32 kgs (2 bags) from KTM to IST and 23 from IST to SFO?
