We reserved a ticket and a seat on Eurostar train from London to Brussels on 22 September at 19:34. We would like to take an earlier train that day but it looks like all the earlier have either no tickets or seats. What are the chances of being able to buy a ticket and seat on an earlier Eurostar train by simply showing up early at the st pancras train station and talking to a Eurostar ticket agent? We would use the Eurail global pass to buy the ticket.
