Changing coupon-code discounted flight
A while ago a booked an intra-european AZ r/t in business during one of the discount days (30% I believe). It now looks that I may have to change one of these flights.
However when I view my itinerary online it doesn't shown any means of changing the dates. Weirdly it shows two payments: One for my 70% of the price (with my creditcard suffix) and one for the 30% portion (with a creditcard unknown to me).
The flights were booked in C so I would expect them to be changeable. But before I start messing with the itinerary by calling AZ, since I don't know details for the new dates yet, what are other peoples experiences with these cases?
Are these treated as a regular C booking that was paid in full (as the full non-discounted payment is shown, paid for by two different creditcards), or, will they make me pay the 30% extra that was discounted previsouly?
Thanks!
