Running three flights per day to JFK at 85% load factors is still not enough for Jetblue as expansion stagnates in SYR. They want the passenger costs in line with ROC and Burlington. SYR recently raised their landing costs close to $3. from $1.71, and then lowered them nominally to appease a recent Neeleman tirade. Still the passenger costs are about $2. per pax higher in SYR.
It's hard to believe SYR can't compete with ROC costwise. Afterall, I believe ROC has spent larger sums in airport terminal construction and infrastructure.
