I'm not an expert, but you may be stuck with the 14 days advanced reservation rule on this (OLXECOUS) fare, only way forward is to pay the 200UDS service fee, upgrade the fare for less restrictive (maybe Y/B/H) fare and pay the difference.
Thanks for the tips so far.
Not sure why a simple date change is so complicated with AY. My experience with other carriers is a lot more straightforward. Usually after first segment is flown, there will be no repricing and you will be able to change the date (if changes are allowed) by paying the reissue fee as long as same fare class is available.
