In the halcyon days of the Northwest Airlines standby airpass, the minimum connecting time was about two minutes. Once you had invested in the unlimited travel pass, staff were happy to help you make the most of the opportunities.
I was flying in from Charlottetown, capital of Canada’s Prince Edward Island (with US pre-clearance before the flight). The plane parked right next to an aircraft heading for Baltimore. It was a simple matter of wandering across the apron and asking the cabin crew member at the door to secure a seat, strap in and make for Maryland.
