ADVANCE BREAKING NEWS:
Trenitalia has announced a brand new fare structure for its "national" (reserved) trains, to take effect on June 10, 2012. There will be THREE FARE LEVELS:
BASE FARE: tickets will be changeable and refundable (with conditions and restrictions)
ECONOMY: tickets will be changeable (with conditions, restructions, and a fare upgrade) but not refundable
SUPER ECONOMY: tickets will be nonchangeable and nonrefundable.
The "MINI" fares, which have become the "rage of the town" in the recent past, will essentially be replaced by the Economy and Super Economy fares beginning next week.
Look for further updates here in the next few days.
