I know they flew them to Honolulu. In 1992, I was in first class on a Delta L-1011 from HNL-LAX-LAS. Our flight was delayed in HNL to wait for passengers from an America West 747 that had blown tires on takeoff and returned to the airport. The lady next to me was from that flight and she was complaining about Delta's first class seats, saying how America West had much more comfortable first class seats with a lot more legroom. She was going to Las Vegas like I was, and she was very upset that Delta wouldn't let her stay on our flight to Las Vegas. She had to get off in LAX and catch an America West flight to Las Vegas. I think America West got rid of their 747s shortly after that.
