- Flying London to Brussels still wins when a connection already ticketed through BRU, or a sharp promotional fare that still wins after transfers.
- Search Omio and Rail Europe for Eurostar; confirm seat and luggage rules on the operator ticket.
- Skip rail-first thinking if anyone whose real destination is Charleroi-linked budget aviation with a hotel already near that airport.
