Pan Am not only crossed the Pacific (of course), they also flew (with 707s and later 747s) from Sydney to Bangkok, Sydney to Singapore and Sydney to Hong Kong as stand-alone routes. The 747s saw Beirut, Tehran, Istanbul, Cairo, Karachi in the near east (plus a few Gulf ports), Saigon (scheduled), you name it.
NZ767: "[As for the 707 days] ...I was just a dirty thought in my old man's mind then so I'm no help there either. Brings back a few memories though." Memories of what? You naughty boy. Etc.
fly Saha Air 707s daily from Tehran's downtown Mehrabad to Mashhad, Kish Island and Ahwaz
