I am glad to say, the AA and the CO mileage awards WOULD allow a stopover in HNL, only on a routing that would include HNL as the stopover.
So OGG-HNL-LIH is possible on a mileage interisland award. And it would require a total of 15,000 miles (5K on AA and 10K on CO awards)
The same ticket, if bought on HA, for the 2 of us, costs $306.40 USD.
which option is more "cost effective"?
