In addition to Earhart and Noonan, Harry Manning and Mantz (who was acting as Earhart's technical advisor) were on board. Due to lubrication and galling problems with the propeller hubs' variable pitch mechanisms, the aircraft needed servicing in Hawaii.

One of the recommended schedules was: Earhart used part of the above schedule for the Oakland to Honolulu leg of the first world flight attempt.

Using 900 gallons was 250 gallons less than the Electra's maximum fuel tank capacity; that meant a weight savings of , so Earhart included Mantz as a passenger on that leg.
