It was not unusual at Glasgow for the backup to operate ahead of the scheduled flight which confused the pasenegers no end.
I vaguely thought that slots or atc permission to operate was one reason that backups became impossible.
I actually flew on the Eastern Shuttle DCA/EWR in 1964,paying on the plane.
My only trip on a Super Constellation.
