I have tried to order a trip now to MIA from GOT. I started a bit before midnight on the 30/12 and now suddenly the prices went up a lot. I have checked the ticketing rules and they say:
Category 15: Sales restrictions
TICKETS MUST BE ISSUED ON/BEFORE 31DEC 18.
Doesn't that mean that the prices are valid to and inclusive of 31/12? Or does it mean that they are not valid on the 31/12? For me ON should also include the 31?
