I have (as ever) no idea what you mean. JetBlue are looking to compete with the US major carriers, United, Delta and American, all of which exclusively use LHR. This immediately puts JetBlue at a competitive disadvantage in the London market against their competitors. This is the same reason WestJet continue to apply for LHR slots so they can more effectively compete with their own major carrier, Mapleflot, er...Air Canada.
It's all about relative competitve advantage, not something a market saturation pro like Emirates is too worried about as they've got the whole region covered all on their own metal.
