The current downloadable timetable only goes up to the end of March and my travel plans have now spilled into April. Anyone know when an updated timetable will be available?

Researching fares in April show a big price increase to that of March. It was mentioned in another thread (which I can't find) that discount fares wouldn't be loaded yet for the April schedule. Anyone know when those discount fares will appear? I need to make preparations soon but not at current prices.

Thanks.
