which runs along the eastern edge of the airport between Chaffey College and Ontario–East station, where passengers can connect to Metrolink's Riverside Line, which operates during weekday peak periods. Noise restrictions Ontario has few noise restrictions/abatement rules, unlike other Southern California airports such as John Wayne Airport, Bob Hope Airport, Long Beach Airport, and San Diego International Airport, which all have very strict policies. The airport is allowed to operate 24/7, but during the hours of 10 pm to 7 am, all aircraft must arrive from the east on runway 26L or 26R and take off to the east on runway 8R or 8L, depending on ATC instruction. This procedure is known as "Contra-Flow" operations and applies to turbojet or turbofan aircraft. This procedure is similar to the one employed by LAX, where all landings are conducted from the east and all takeoffs are to the west (known as "over-ocean" operations) between midnight and 6:30 am. Both of these procedures are employed as long as weather and/or construction activity permits. This is done in an effort to be better neighbors and minimize the noise impact to the surrounding communities as much as possible. Residents of cities west of the airport have complained of increased noise as a result of the airport's refusal to abide by noise abatement rules.
