I have a question (pretty hard one). I am on the Business Premier ticket in which is fully flexible, I am going from London to Paris, once I have checked in and passed the immigration check (for Schengen visa as I need visa), BUT NOT getting on the train yet. Will I be able to change this journey to the other date and leave the "sterile" international area back to London again for free of charge (or to refund the ticket)? This is due to my personal circumstances.
