A real nightmare !
My husband is an Elite Plus member and a just called the helpdesk in order to get the free upgrade but the answer is : SORRY NOT POSSIBLE and why ? The system doesn't allow the free upgrade or any upgrade for your ticket !
The ticket is economy Q class, an expensive class for economy !
On TK site it is written that Q class economy is eligible for upgrade.
We fly TK for many years in order to benefits from their advantage but now I'm very very very disappointed about this answer !
Shall I continue with TK or change ? What do you think ?
