Unfortunately, flights are changing constantly due to the ongoing pandemic and flight demands. It isn't just Hawaii, but flights all over the Southwest route map. Most of the time you should get an e-mail regarding any flight changes Southwest makes, but there are times this doesn't happen so it's recommended to keep an eye on your flights well in advance of your takeoff in case any changes arise. If they do, you should be able to make changes free of charge for a period of time, and if you have trouble, Southwest should be able to assist you in making changes. Contacting them via Social Media (not phone) is best, as they are often quicker to respond. --Jessica
