My favorite has become the requests this time of year by a few Alaska FAs on the red-eyes from LAX to JFK that depart around 9 PM and arrive at 6 AM. The request has been "to be kind to your neighbors as the sun will be coming up upon arrival". Perhaps they are native West Coasters unused to the unabiding darkness that is the East Coast these days, but it has always been dark at take-off and equally so upon arrival.
