beside my LH ZRH-FRA segment the LAX-SNA segment is my record-flight segment (and, not always, but in most cases included in my transatlantic ticket for free).
And, if credited to my LH miles&more account I even get 1'000 miles as status miles (the minimum for eco flights).
SNA RCC is very nice and very personnel (if, from time to time, an Express flight seems to become late for a LAX-connection, they offer me a free Limousine alternative)
SNA is very clean, with much day light (windows).
SNA: rented cars are easy/very-fast to 'board' and to return (may be a 150 yard walk from the baggage-area).
And traffic/parking around SNA is not a mess as in LAX.
SNA = Orange County Airport = John Wayne Airport.
