pay is approx $1300/month before taxes once you are qualified. Rent is outrageous...I just got a studio with street parking, no washer dryer, and a hotplate and a microwave for cooking for $750/month...and I am THANKFUL for it!
You are not an employee during training (haven't figured that one out yet) so you only get paid while you are actually in training. If their is a large space between ground school and simulator (there almost definetly will be, as much as 6 weeks) you will have a large gap without pay.
You are not provided housing of any sort (not even a discount at a hotel).
As far as commuting goes..."true commuting" is not possible as we only have day trips. The few pilots that do "commute" here bunch their days off so they can go back and forth but you will still end up spending 1-2 weeks at a time away from home. I do not know of any crash pads in Hawaii. Not that i've been looking though.
Commuting is also tough as we are not allowed in the jumpseats of any other airline. Hawaii is a popular place and getting a flight to the continent can be nearly impossible during certain times. When I worked for Eagle getting back and forth was a cinch as we could at least ride in the cockpit of American. Their were days during the summer that their were over 100 standbys waiting for a flight. PSA gets into USAir cockpits, Express Jet rides up front on Continental...we don't get any of that. CASS is supposedly in the works, but I would be surprised if it was up and running in the next 12 months.
The fact that you are even considering commuting would make me tend to believe that Island Air is probably not the place for you. Their are basically two types of people that thrive here... The folks from the mainland that have dreamed for a long time about LIVING in Hawaii...they love the surf...the hiking...the dark skinned wahine...whatever. The other group are the locals who have strong ties here that wouldn't dream of leaving and/or have a cheap/free place to live. Read the other island air thread and you will probably get more information about surfing in Hawaii than what it's like to work for island air. This is indicative of why people come here.
The "price of paradise" is extremely high. If you come here with a large savings account, a love of the outdoors, and a good attitude, you will do fine. Otherwise, a bunch of other regionals are hiring, use your jumpseat privliges to come out and visit once you're done with training.
good luck
