A friend just presented me with an interesting travel question, and I'm not quite sure whether it's possible to find this info.
He wants to go to Hawaii in June. He has two free tickets on United from a denied boarding that are good to anywhere in the continental US. So he wants to find what city has the cheapest round trips to Hawaii, use his United passes to fly to that city, and then fly to Hawaii. He knows that wouldn't be a single itinerary, he'd have to recheck his bags, United's not responsible if he misses his connection, etc. He'll probably plan to fly to the city the night before.
So how does one find out what city has the cheapest fares to Hawaii? He doesn't care which city in Hawaii he flies to, and his travel dates are completely flexible. The only problem is that his United passes are about to expire, and he has to book that part of the flight by 3PM tomorrow. Any ideas?
