Both "leisure select" and "business premier" have 1 printed in the Class box on the ticket and I have personal experience of a "leisure select" ticket LONDON ST-PANCRAS to BRUXELLES MIDI endorsed "Valid from/to Any Belgian Station" being accepted without question in First Class on SNCB/NMBS.Does anyone know what class you can travel in on your connection from Brussels to "Any Belgian Station" if you have a "leisure select" or a "business premier" Eurostar ticket?
Could you really get done for being in standard class with a first class ticket?
I suppose there's a certain logic, in that you are depriving someone in standard class of a seat when you're supposed to be in first class.
