What I have found rather „strange“ the past 2 weeks is that I‘ve made 2 1-way booking (if you combined it would be an open jaw) on different departure dates, but one of them (quite random) gets cancelled automatically before the holding period expires i.e. cancelled like 2 days after I‘ve put them on hold. This happened 3x already … now I have to keep checking everyday and see what they randomly cancelled. This seems to be some bugs in the system.
