The Game Plane

Passengers on (generally longer) Allegiant Air flights compete by playing various games while on the plane to win prizes such as cash or vacations. The bonus round is played by the two players who won the most in money and prizes during the first three rounds of the show and is played like Card Sharks, where the players have to guess whether each card held by a person on the flight is higher or lower than the previous card. The player or team who guesses the most right in a row wins a bonus prize. (Source: The Game Plane)
