An away-travel booking should tell supporters which journey they are buying, where they board and whether a match ticket is included. An app could keep those details together with booking confirmation and departure updates.
Seat capacity, pick-up points and waiting lists need to reflect the actual coach arrangement. Organisers would benefit from an accessible boarding list, including an agreed fallback when mobile reception is poor. Contact details should only be available to staff who need them.
Define how cancellations, substitute passengers and postponed fixtures will be handled before taking payment. A practical pilot could cover one away trip. Check that a cancelled seat returns to availability correctly and that a change of departure time reaches everyone booked, rather than only people who happen to reopen the app.
