After a 25 year marketing partnership Southwest Airlines and SeaWorld Entertainment are officially calling it quits. Although it is said the decision was mutual, the airline has been urged by animal rights activists to terminate the relationship following the recent term-oil following the"Blackfish" documentary. The partnership will not be renewed when the current contract expires at the end of this year. Three Southwest airplanes had SeaWorld animals painted on their bodies per the partnership. Those planes will eventually be painted over to Southwest's traditional look. SeaWorld also had Southwest signs in its parks, and Southwest offered vacation packages to SeaWorld. These vacation packages will continue to be offered. SeaWorld will continue to concentrate on growing markets in Latin America and Asia. "Southwest and SeaWorld have enjoyed their long relationship, and wish each other continued success," as per a statement from the company.
