This is just a guess, but I think JetBlue is waiting to see what happens with United's bankruptcy proceeding (as it relates to its IAD hub) before making any serious moves there. Once it becomes clearer what direction United is headed, then JetBlue will likely take some action. For instance, if United eliminates the IAD hub, we could see JetBlue adding service from IAD to nearly every city the carrier serves, such as SEA, LAS, SLC, DEN, MSY, various Florida cities, SJU, and perhaps even JFK and/or upstate New York. On the other hand, if United's IAD hub remains largely intact, then I think JetBlue will simply add a few incremental flights every year to Florida and the West Coast, as equipment availability permits. And I think that PBI and RSW service from IAD would be high on JetBlue's list because there is relatively little such service from the Washington area and none from IAD. But we'll just have to wait and see. JMHO.
