B2N2 - Would a longer runway have really helped in this event? The choice of runway depends on what your company's requirements are. If they say flex at any cost, then so be it. But if are going to run out of duty time, run out of MEL time, miss your slot, run out of HOT, miss connections, hit noise fines for late arrivals then maybe not. To decide, you need more information than just runway length.
These are all items that (ideally) should not be taken into account to cut corners on what is basically a safety decision.
