Normal LAX ops. When I was with SkyWest, anytime I did a super early arrival into LAX from a relatively close place like SBA, we always landed East. The other night, now with SWA, we left around 10 pm and even though our gates are a stone's throw to 24L they had us taxi all the way to the South complex for a 25R departure. For noise abatement they had just started landing aircraft East on the 24's while still launching aircraft West on the 25's.
Pretty much every airport in the LA basin has noise abatement policies. Secretly I would really love it if one of you military guys would depart Orange County between 11 pm and 6 am at full burner. . . . Of course while complying with the published noise abatement procedure.
