For years, JetBlue Airways (NASDAQ: JBLU) has vacillated in its commitment to Long Beach, California: its smallest focus city. JetBlue began building a mini-hub in Long Beach in late 2001, just a year and a half after it started service. However, while it has tried a number of strategies there, none have been terribly successful in recent years.As a result, JetBlue recently decided to implement big cutbacks in Long Beach.
