A new marketing strategy has been partnerships with professional sports teams and venues. As the official airline of the New York Jets, JetBlue has specially painted the exterior of one of their Airbus A320s (N746JB) in the team's colors. Aircraft N605JB is based on the design of the Boston Red Sox road uniform and sports a grey fuselage with navy lettering. This aircraft was unveiled in February 2012, just in time for the opening of the Red Sox new spring training facility in Fort Myers, Florida named JetBlue Park at Fenway South. Additionally, JetBlue and MasterCard have pledged to refund select flight purchases made online at JetBlue.com using a MasterCard. JetBlue has also partnered with various other sports teams and sporting venues in cities they serve.
jetBlue expanded service to the Caribbean, including to St. Maarten and Puerto Plata commencing January 10, 2008. With these additional destinations, jetBlue serves a total of twelve Caribbean/Atlantic destinations including Aruba; Barbados; Bermuda; Cancún; Nassau; Aguadilla; Ponce; San Juan, Puerto Rico; Santiago; and Santo Domingo, Dominican Republic.
jetBlue also utilizes various forms of advertising media. They use print, online, and television ads as well as advertisements on popular social media sites including Hulu and YouTube. jetBlue emphasizes a secondary slogan, "If you wouldn't take it on the ground, don't take it in the air" poking fun at competitors with hidden fees, little, or no amenities and what jetBlue considers an unacceptable level of customer service.
While its financial performance started showing signs of improvement, in February 2007, jetBlue faced a crisis, when a snowstorm hit the Northeast and Midwest, throwing the airline's operations into chaos. Because jetBlue followed the practice of never cancelling flights, it desisted from calling flights off, even when the ice storm hit and the airline was forced to keep several planes on the ground. Because of this, passengers were kept waiting at the airports for their flights to take off. In some cases, passengers who had already boarded their planes were kept waiting on the apron for several hours and were not allowed to disembark. However, after all this, the airline was eventually forced to cancel most of its flights because of prevailing weather conditions. The fiasco reportedly cost JetBlue $30 million.
In March 22, 2010, jetBlue turned down incentives from the City of Orlando and announced its headquarters would keep its Forest Hills office, start leasing and using a new office in the Brewster Building in Long Island City, New York. in Queens Plaza in Long Island City, move its headquarters there in mid-2012, and start a joint branding deal with New York State using the iconic I Love NY logo.
In February 2012, Frontier Airlines cut five nonstop routes from Milwaukee. This move "reduced Frontier's daily departing flights out of Mitchell International from 32 to 18," or 56%. Frontier announced further layoffs in conjunction with this route change: up to 446 Milwaukee-area employees were affected by the job cuts that occurred between April 15 and April 30, 2012.
