Is it planned to add point of origin avaialbility for airlines that mandate this (AF/ KL, QR etc)? I understand this kind of discrimination comes to replace point of sale discrimination. Unfortunately, currently it is not possible to get accurate information for airlines using POI availability discrimination.
For example, If I fly from MOW to BKK via PAR on AF I cannot currently get accurate availability for the return journey (BKK-PAR-MOW) because that journey's availability will be shown using BKK as POI and availability does vary significantly (well for lowest booking classes at least).
ITA Matrix does differentiate availability based on POI (a return/ multi city journey search is required of course).
