How long time in advance can I book Flixbus bus tickets for traveling in Europe? When I try with a route that normally runs daily (out of Prague) for June 1, 2020, their web site refuses with:
Unfortunately there are no trips on this route on the selected date
I guess this is because the date is still too far out, perhaps even after their next upcoming change of served routes and timetables. I there any offical communication from Flixbus on this topic?
