I trust Boeing was very grateful to Britannia for many years for leading the way with the 732, although it was another ten years before another British charter airline - Air Europe - was to order the type. Dan Air, Monarch and British Airtours were still flying Comets, 1-11s, Boeing 720s and 707s and Orion was still a couple more years away.
Speaking of airline charter arms, I flew to and from Ljubljana in 1986 with Air Yugoslavia. We were on a 727 both ways and, apart from the 'JR' prefix and the 'Yugair' RT callsign, it was JAT Yugoslav Airlines. Obviously, some airlines decided to put a little more distance between themselves and their charter cousins, e.g. Lufthansa with Condor and Sabena with Sobelair.
