Are you planning your summer holiday? The first Saturday in January is called Sunshine Saturday because typically more holidays are booked on that day than on any other in the year. Today, planning a trip might involve consulting AI rather than reading a travel guide or visiting a travel agent. And the trip itself is more likely to involve an airplane than a stagecoach. But it's not just the practicalities of travel that have altered over the years. Reasons for travelling have changed, so have the meanings assigned to it. Was it ever a good vehicle for self discovery? Shahidha Bari is joined by award-winning travel journalist Mary Novakovich, TV globe trotter Bettany Hughes, historian Alun Withey, literary historian Lucy Powell and philosopher Julian Baggini.
