Well, there is the Adak - Midway - Honolulu route. I think the
longest leg, Adak/Midway is about 1400nm.

It may be showing incorrect results, but the Google Earth product's
measuring tool shows the distance from Adak, Ak to Midway Atoll at about
1800 nm.

The only other route (not all the intermediate steps worked out!) seems to
be:

Aleution island chain - Yokohama, Japan - due south to Saipan via another
chain of islands - Palikir Island via some other possible smaller island
stops - Wake Island - Midway Atoll.

The Wake/Midway leg appears to be about 1200 sm or ~1040 nm.
