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.
During the last few days of June and the first few days of July 2015, jetBlue began charging for bags in certain booking classes, leaving Southwest Airlines the only major U.S. carrier to not charge for bags. For the classes in which bag check fees are charged (generally the lowest class of fares offered; jetBlue offers 3 classes of fares), the cost is $20 for the first bag and $35 for the second, which is the lowest in the United States besides Frontier Airlines with similar prices.
On August 4, 2008, the Associated Press reported that jetBlue would replace their recycled pillows and blankets with an "eco-friendly" pillow and blanket package that passengers would have to purchase for use. Each package will cost $7 and will include a $5 coupon from retailer Bed, Bath and Beyond. This decision is the latest in a series of moves designed to increase revenue. jetBlue told the Associated Press that it expects to collect $40 million from passengers selecting seats with extra legroom and $20 million from passengers paying $15 to check a second bag. As of September 8, 2008 JetBlue charges passengers $10–30 for an extended-leg-room seat depending on the length of the flight.
jetBlue previously had its headquarters at 80–02 Kew Gardens Road, and then in the Forest Hills Tower, both in Forest Hills, Queens, New York City, 6 miles (9.7 km) from the current office in Long Island City. In 2001 the airline had announced that it wanted to take 74,000 square feet (6,900 m2) of space in the Forest Hills Tower, and by December 2002 announced that it planned to increase its leased space.
In an effort to focus on regional contract flights for major carriers, Republic Airways Holdings announced in January 2012 its intention to sell or spin off Frontier. On January 26, 2012, Republic Airways Holdings appointed former US Airways and Gate Gourmet CEO David Siegel as President and CEO of Frontier Airlines. Republic also added new senior officers for Frontier's finance and commercial team, among other changes in the executive leadership team. Siegel and other Frontier executives moved to Denver where Frontier is headquartered in order to facilitate management of all aspects of Frontier during its separation process from Republic and continue its transformation into an ultra-low-cost carrier.
