I must agree that non-reving to HA especially in the summer can be difficult. I do not work for ATA but have non-reved on my own airline and other airlines to Hawaii many times to give you some tips. If possible, try flying on offpeak days on midweek days like Tues, Wed, Thurs (Thurs can go either way--good or bad). I have found OGG is not quite as bad as HNL. ATA is a small airline with not that many employees to compete with so that works to your advantage. Other airlines like UA, AA, DL, NW, CO, US/HP their is a large employee pool base trying to non-rev to Hawaii. Not only are employees trying to non-rev but their eligible travelers like spouses, parents, children, plus guest passes are also trying to non-rev. Believe me I know this all to well. Also, are you set on leaving from PHX? ATA also serves Hawaii from LAX, LAS, OAK. Another tip is if you cannot get directly to OGG, then ask ATA how their HNL flight for standby travel. If they should tell you HNL looks better than OGG then try to get to HNL. Nowadays you can get a inter-island flights on Hawaiin, Aloha or GO! Airlines (Operated by Mesa) for $30 or less. Last year, I got bumped 2x going to HNL from PHX on HP. I finally decided to fly on HP to LIH, then booked Aloha to HNL for $30. It costed me a little, but a I got there. Good luck and have fun in Hawaii. Also, when you book your hotel, you may want to ask about "bump" protection. Do not pre-pay your reservation for hotels or car rentals as you are not guaranteed getting there.
