Carnival Cruise Line is inviting vacationers to look to the skies with its latest campaign, which includes a 128-foot-long red, white, and blue blimp called the Carnival AirShip.

With “#ChooseFun” written across its side, the airship launches as part of the company’s “Homeport Advantage” campaign, and was created to raise awareness of the cruise line’s ship deployments across several markets on the Atlantic and Gulf Coasts. It made its official debut at St. Jude Children’s Research Hospital, located in Memphis, Tennessee. From there, it embarked on a 30-day journey across several states, with upcoming appearances in Dallas, then Houston, Texas.

Other stops along the way include in Carnival homeports in Galveston, New Orleans, Mobile, Tampa, Miami, Fort Lauderdale, Port Canaveral, Jacksonville and Charleston before finally stopping in Atlanta. The related website includes a tracker so that fans can see where the airship has been, where it is and where it’s headed.

Carnival is also giving away swag along a chance to win free cruises, VIP passes and gift cards when people post photos and videos of the airship to social media with the hashtag #ChooseFun. As an added bonus, the hashtag also triggers a donation to St. Jude Children’s Research Hospital.

“Carnival is America’s Cruise Line and what better way to showcase our new offerings in popular homeports like Galveston, Port Canaveral and Miami than with our very own airship that highlights our #ChooseFun tagline while supporting the special kids at St. Jude Children’s Research Hospital,” Christine Duffy, president of Carnival Cruise Line, said in an announcement.

The “Homeport Advantage” campaign is designed to raise awareness of Carnival’s 18 year-round seasonal ports located along the East and West Coasts and the Gulf of Mexico. According to the company, “roughly half of the US population is within a day’s drive of a Carnival homeport.”
