Southwest Airlines and Discovery want to send you on an envy-inducing diving trip in Nassau, Bahamas. Included in the 'Dare To Dive' sweepstakes are round trip Southwest airfare for the grand prize winner and three companions; a $3,000 gift card to The Island House; along with a $375 gift card to Stuart Cove's for a diving excursion.

By the way, no purchase is required for you to enter the 'Dare To Dive' sweepstakes. The sweepstakes is open to legal residents of the 50 United States and D.C. (excluding Alaska), aged 19 or above, through July 31, 2019.

While the grand prize is indeed a lavish one worth about $4,975 in retail value, keep in mind you are required to fork out money on international air travel taxes and fees if you happen to be the grand prize winner. These are not included in the free round trip airfare that's part of the grand prize.

In addition to running the sweepstakes, Southwest Airlines and Discovery have partnered to bring Shark Week to travelers this summer, ahead of Discovery Channel's Shark Week scheduled to start later in the month beginning July 28, Sunday.

Passengers on Southwest WiFi-equipped flights can look forward to enjoying exclusive Shark Week content via Live TV during flight on Southwest's Shark Week On-Demand Channel. The highlight includes Extinct or Alive: The Lost Shark, a never-before-seen episode Southwest customers can watch ahead of its premiere during the actual Shark Week from July 28 to August 4.

The fun does not end there. On the ground, Southwest passengers flying out of 40 airports can already enjoy interactive games hosted by Southwest employees. Of course, Shark Week materials are available at the gate areas.

Also, fans of Shark Week and sharks can indulge in an augmented reality experience through their cell phone. Accessible via swa.is/sharkweek, the special filter allows users to ‘swim with sharks'. Your fun experiences ‘swimming' with the Great White Shark, Hammerhead Shark, Mako Shark, Tiger Shark, and Bull Shark can all be shared on social media using #SharksTakeFlight.
