Well, just to tease UA mainlanders from certain cities, FWIW, here's a crop of map of the airports that pmUA flew _non-stop_ to HI back in May 1970 (courtesy of
erussell1984/airbus777 on Flickr):
Note that this is _prior_ to delivery of UA's 747s. I get LAX, SFO, SAN as well as ORD, WAS and NYC - but this map shows DTT, KCI/MCI, BUF, CLE, PIT, BOS, PHL.
Let's see if UA opens up some of these routes non-stop back to the islands in the future...
