Sacramento doesn’t see a lot of flight deals. Sadly, there are no budget carriers currently operating from SMF, I don’t know why that is.
That said, this is a VERY nice deal to Maui through the end of Summer and early Spring. I found a bunch of dates starting in the $360’s round-trip. Sorry, no United Airlines jokes in this post, shucks.
I recommend searching for flights on google.com/flights before heading over to United.com. Just search SMF to OGG. Since this deal is currently offered by United, you will have a layover in either San Francisco or Los Angeles. I saw layovers as little as 90 minutes, which is not bad at all.
If you are a little nervous flying over the ocean, I’d recommend looking for flights operated on the Boeing 757. That is one of the largest single-aisle planes and will help soak up the bumps better than a 737.
Checked baggage fees are $25 for the first bag, $35 for the second bag, up to 50lbs a piece. Keep in mind the cost is each direction, so $25 there and $25 back. You are allowed a small personal item, like a backpack, and a carry-on suitcase in the cabin. (Plus a free knuckle-sandwich is served in-flight, okay I lied about the joke)
United offers a Fare Lock feature that allows you to “lock” the price with no obligation for up to 7 days. At this price, $8.99, I would highly recommend it if you need a week to make other plans. As with all US flights more than 7 days from departure, you always have 24 hours to cancel for a full refund. Don’t wait if you find dates that work, they certainly won’t get any cheaper!
