Meanwhile, American and JetBlue have been engaged in a turf war over Kennedy Airport in recent weeks. They already compete in the Kennedy-South Florida market and American is starting to take on JetBlue between Kennedy and Oakland and Ontario, California. JetBlue, meanwhile, will move into American's back yard next month, with Kennedy-San Juan flights. This market has been dominated by American since its acquisition of TWA last year. While the IPO will raise working capital and assist with the purchase of additional A320s, Hamlin believes it will ensure JetBlue "has sufficient cash on hand for a war chest", so it is prepared to go head-to-head with carriers such as American.
