...then why does Southwest's daily BWI-SJC flight consistently use -700s that are still without winglets?? Seeing a -700 without winglets at SJC is becoming more and more rare these days but if there is one flight that consistently comes in without winglets, its the BWI-SJC flight that is supposedly the longest flight in the system. The flight wont be around much longer anyway, but it just seems kind of ironic to me. You would think they'd route only aircraft with winglets for that flight. There seems to be enough in the system by now.

The main driver of aircraft routing is assuring that the aircraft hit selected maintenance facilities at certain times for overnight work.
A couple of months ago, a non-wingletted -700 on a BWI-SJC might have been problematic weight-wise, but we've since completed the engine upgrade from 22,000 lbs of thrust to 24,000 lbs. and that has mitigated the absolute need for a wingletted -700 on this route. If we still have a weight problem, and a wingletted -700 will solve it, we'll put one on it as long as the overall maintenance routings are not compromised. In another few months, it'll be a moot point, as all the -700s will have been retrofitted with winglets.
Next time you're at HDQ, stop by Dispatch and see how things work here....
