More than 200 passengers were delayed when Hawaiian Airlines diverted a Honolulu-bound flight from Oakland, Calif., to San Francisco Sunday. The flight landed in Hawaii early Monday morning.

Honolulu flight HA47 departed Oakland International Airport at 9:45 a.m. Sunday, but about 20 minutes into the flight the pilot was alerted to an indication of trouble with the right engine on the Boeing 767 and decided to divert the plane to San Francisco, spokeswoman Ann Botticelli said.

Hawaiian, a subsidiary of Hawaiian Holdings Inc (Nasdaq: HA), kept the plane at San Francisco International Airport, where it is being examined, she said.

The 203 passengers were taken by bus back to Oakland, where they were given meal vouchers and the option to check into a hotel, she said. Later on Sunday, a Hawaiian flight from Honolulu that landed in Oakland around 10 p.m. was turned around for a return flight to the Islands, arriving at Honolulu International Airport about 4 a.m. Monday, Botticelli said.

The airline ferried another plane to Oakland for its regularly-scheduled Monday flight to Honolulu, she said.
