The passenger list included stage and film actor Leslie Howard; Alfred T. Chenhalls, Howard's friend and accountant; British journalist Kenneth Stonehouse, a Washington, D.C. correspondent of Reuters news agency, and his wife Evelyn Peggy Margetts Stonehouse; Rotha Hutcheon and her daughters Petra (11) and Carolina (18 months); Tyrrell Mildmay Shervington, director of Shell-Mex and BP Oil Company in Lisbon; Ivan James Sharp, a senior official of the United Kingdom Commercial Corporation (UKCC); Wilfrid Israel, a prominent Anglo-German Jewish activist working to save Jews from the Holocaust; and Gordon Thompson MacLean, an Inspector of British Consulates.

Flight 777 was full and several would-be passengers were turned away, including British Squadron Leader Wally Lashbrook.
 Three passengers disembarked before departure.
Derek Partridge, the young son of a British diplomat, and his nanny Dora Rove were "bumped" to make room for Howard and Chenhalls, who had only confirmed their tickets at 5:00 the night before the flight and whose priority status allowed them to take precedence over other passengers.
 A Catholic priest also left the aircraft after boarding it, but his identity remains unknown.
Anne Chichester-Constable, 7-year-old daughter of WRNS Chief Officer Gladys Octavia Snow OBE was also booked on the flight which connected her return to England from New York.
At the last minute, her guardians in Portugal decided that she was too tired and kept her in Portugal.

After the war, actor Raymond Burr said that he had been married to Scottish actress Annette Sutherland when she  was killed on Flight 777, although he could have been referring to another commercial flight also shot down at the same time.
He said he travelled to Spain and Portugal to get information on the disaster but never learned anything about it.
According to Burr's biographer Ona L. Hill, "no one by the name of Annette Sutherland Burr was listed as a passenger" on Flight 777.
