There is a slight chance that Peter is in the "mix up mode" when it comes to runway headings, wind directions and favourable departure routes.

The KLAX departures offer procedures for every runway direction of course, but the noise preferred departure routes are over the ocean, for obvious reasons. So westbound departures are indeed common practice as far as I can see.
If the tailwind component goes above 10 kts, they seem to switch their westbound preference though. Again, obvious reasons.
The planned destination in regard to the departure direction should only matter in the very short route regime, e. g. on the TEC routes.

However, how did your St. Maarten approach work out, boeing247?  :) Shocked tourists or some which enjoyed the show?
