How far in advance do you generally purchase flights for Hawaii? We are traveling to the Big Island at the end of July. I am great with Southwest - but as a result am really terrible with other airlines now! We will use points to get to the west coast from Chicago, but I am not sure what constitutes a good fare for the end of July/early August. When would you purchase and what price range would cause you to pull the trigger without any hesitation? Which airlines do you find to be best and which western-US airports have best flights/lowest fares? I have seen good remarks on San Jose, Pheonix and San Diego and Alaskan and Hawaiian airlines. I would hate to overlook an airport or carrier that is reliable and offers better rates. It will be myself, husband and 2 DD's (8 and 5 at the time) traveling.
