Dear community,
I was wondering about the use of e-vouchers (not miles) to upgrade a longhaul TK flight (IST-KIX).
- Do I need two e-vouchers?
- Which classes are eligible to be upgraded, is it only Y and B?
- Can I assume that the upgrade will work if there is availability in J, or which class do I need to look for?
- Can this be done online/in advance for TK issued tickets?
Thanks for any helpful replies!
