Can't get a booking to work the way I want at all. At the moment the two routes (ACH-VIE and ACH-CGN) price out at a best fare of EUR198 round trip. While prices on ACH-CGN are reasonable up to Christmas, if you book something with a return in January (or anything at all from January) the price of the outbound remains steady at EUR99, but the return goes up to EUR259 and I can't get it any lower. Is there any reason for this, or is there just a bug in their system?
