Yes off topic. I re-read the post where this was discussed. US West Coast was mentioned, not LAX specifically. SEA may be what was referred to. The poster must have been talking about a DH to SEA followed by returning to DXB 12 hours later, not going to Europe from anywhere on the US West Coast. I assume two different trip types were being talked about. The end result is the same: miserable schedules and burnout because their regulations (or lack thereof) allow it.
