Gatwick Express Web Duo tickets are only available for journeys started from London. However, for a simple day trip, is there anything to stop the tickets being collected from Gatwick and being used Return portion first and Outward portion second?
I can see this being a case of paper tickets being much more flexible than Smart cards if that were the case.
