In October 2005, JetBlue's quarterly profit had plunged from US$8.1 million to $2.7 million largely due to rising fuel costs. Operational issues, fuel prices, and low fares, JetBlue's hallmark, were bringing its financial performance down. In addition, with higher costs related to the airline's numerous amenities, JetBlue was becoming less competitive.
On December 13, 2007, jetBlue and Germany-based Lufthansa announced jetBlue's intent to sell 19% of jetBlue to Lufthansa, pending approval from US regulators. Following the acquisition, Lufthansa stated they plan to seek operational cooperation with jetBlue. Lufthansa plans to offer connections to JetBlue flights in Boston, New York (JFK), and Orlando International Airport (no longer a connection).
