There's probably a better place for this post, but there's a tangential link here, so...
I had an interesting thing when I was looking for flights for the weekend. I usually travel Qantas, and pay for flexible economy or discount premium economy then rely on the points lottery if I want to upgrade, but I search on an aggregator to see if there are premium cabin, or any other deals just in case. This time I searched Sydney to Los Angeles and used 'all airports' instead of LAX. Delta had business class around AUD10k R/T to LAX but around AUD6k to Long Beach, Ontario or Orange County, flying into LAX then to LAS, SLC or PHX and back to those LA-area airports. I was almost tempted but Qantas came up with a bonus elite status points deal that worked better for me at the time (and I bought flights into PSP on that).
