Hi all. I'm need to travel from Birmingham International to Euston on Sunday. Ideally I want a flexible ticket. When I use the Virgin website and search for a single ticket BHI-EUS with a Y-P card the only flexible Off-Peak single ticket offered is £28.40. If instead I search for a return journey EUS-BHI-EUS I am offered "Off Peak Single (Online only)" tickets costing just £14.50 each way. What's going on here? If they are singles then why aren't they offered when I search for just a single from BHI-EUS.
