Knobbgb It says the highest number of miles in Flex, so it will be Flex Y just like the "regular passes", the 25th of March is a national holiday, on which many Greeks like to travel.
I can understand the logic behind every black out period, but all together make it way too restrictive!
I think there will be buyers of this pass, who will be disappointed, especially if 3-6 weeks out out no seats are offered!
