"Scuba divers and beach fans long have wished to fly with us to enjoy this underwater paradise," said Bill Tierney, Vice President of Marketing for Southwest, in a statement. "We'll bring the world-famous hospitality and value of Southwest to Cozumel while bringing a new beach destination within reach for our customers, just as we've done before with service to Cancun, Puerto Vallarta, Cabo San Lucas/Los Cabos, the Caribbean and with our growing service for the Hawaiian Islands."

Additionally, the low-cost carrier announced that it's accelerating its timeline for Hawaii service. New daily service between Sacramento and Kahului, Maui will launch March 7, 2020. Other daily flights will include Oakland-Lihue, Kauai; Oakland-Kona, The Big Island; San Jose-Lihue and San Jose-Kona.

Now through 11:59 p.m. PT on October 3, 2019, Southwest is offering interisland Hawaii flights for as low as $29 one-way for travel between November 12, 2019, and April 8, 2020, with the exception of some blackout dates around the holidays. The special fares are valid only for nonstop service Tuesdays and Wednesdays.

"Demand is strong for our Hawaii service and we're not just increasing those routes to daily service for our customers, we're also moving up our timeline on two routes set to begin in January, and instead will fly them this year," said Adam Decaire, Vice President of Network Planning for Southwest, in a statement accompanying Thursday's announcement. "Our flights between Sacramento and Honolulu, as well as interisland service between Honolulu and Lihue, Kauai will now begin November 10, 2019."
