Note - This list occasionally changes. An easy way to check what airlines fly directly into whatever island you are checking is to go to a fare checking site like expedia or cheapoair and search for your flight. An easy to read table and a list will pop up with available airlines into your desired city. I like cheapoair for cheap airline tickets
Note - Aloha Airlines and ATA airlines used to be on this list but both have gone bankrupt and stopped flying.
