Qantas flew RTW service with Constellations, 707s and 747s (barely). As well as the above route (SYD-NAN-HNL-SFO-JFK-LHR and on to Sydney via the Kangaroo route which included stops in cities like Geneva, Belgrade, Karachi et al), they also flew to London via Nadi, Acapulco, Mexico City, Nassau and Bermuda (then on to Sydney via the Kangaroo route again). What an airline. Mexico City to London on a Qantas 707 via Nassau and Bermuda? Now THAT'S exotic.
fly Saha Air 707s daily from Tehran's downtown Mehrabad to Mashhad, Kish Island and Ahwaz
