low-cost carrier Interjet began a new service in October 2012 from Orange County to Guadalajara and Mexico City. It ended both flights in July 2014; the airport officials are seeking a replacement. Alaska Airlines began a Mexico service in October 2015. The airline began offering non-stop flights from John Wayne Airport to Los Cabos on October 8 and Puerto Vallarta on the following day, October 9. Alaska Airlines has continued this service to each airport on an every-other-day rotation. Since August 2019, the airline has discontinued flights to Mexico. Airline officials have also been in negotiations with Mexican low-cost airline Volaris, which has applied for an Orange County slot. Aircraft noise abatement and curfew A 1985 settlement agreement defined the scope of operation for John Wayne Airport in how it affects the local community. The area that lies directly south of John Wayne Airport is considered a noise-sensitive area. The agreement in conjunction with a Phase 2 Commercial Airline Access Plan and Regulation controls the number of noisier operations (mainly commercial aircraft) allowed from the airport. Noise abatement enforcement is carried out with the aid of 10 permanent noise monitoring stations. These stations are placed in areas that exceed a community noise equivalent level (CNEL) of 65 dB. The short primary runway (20R/2L), coupled with the local noise restrictions, can require a takeoff at or near full power (95–97% power). Some aircraft departing from the airport may cycle to full power while holding at the runway then release the brakes when engines are fully spooled up (short-field procedure). On operations from runway 20R a steep climb may also be required to allow for a power reduction at about for a quieter overflight over the city of Newport Beach. For 20R departures, a left turn after departure to 175 degrees allows for a passage over Newport Beach within the confines of the noise abatement profile. Departures from 2L (normally during Santa Ana wind conditions) are not affected by these noise abatement procedures. Landings almost always include full flap extensions and the use of full reverse thrust. Extension of the runway is almost impossible, as both ends are enclosed by freeways, numerous residences, and businesses requiring relocation, which is a costly endeavour. The county prohibits commercial departures between 10:00 PM and 7:00 AM (8:00 AM on Sundays) and commercial arrivals between 11:00 PM and 7:00 AM (8:00 AM on Sundays). Exceptions can
