China Eastern Validation Problem
So I bought my ticket through a third party app. China Eastern does not allow to manage a booking that was not made directly with them, however, they do allow you to change your seats and check if your ticket is real.
A couple of days ago I tried doing both and both came out right. I was able to check my seat (meaning they had my booking on their system) and to get the verification that my ticket is real. Nevertheless, since yesterday it only shows me my seat. In other words, when I go to the validation webpage it says it cannot find my itinerary, what should I do?
