737NG Dispatch/Scheduling Question

Mon Mar 26, 2007 11:28 pm

I recently flew AirTran from DCA to LAS via ATL, and a question occurred to me while on board the ATL-LAS leg: do airlines that fly the 737NG, and who are currently in the process of retrofitting them with winglet kits, try to schedule the airplanes that have been retrofitted on the longer legs to more fully realize the advantages of the winglets? On my flight to LAS, the 737 we were on did not have winglets (the one coming back did). Both DCA-ATL legs did not have winglets either. I'm hoping OPNL will weigh in, but are there any dispatchers from AA, FL, AS, or ATA who also can weigh in?

From an AS perspective:
All but 2 of our 73Gs have winglets, but there really hasn't been a concerted effort to keep the wingletted
aircraft on certain routes. I think if we had a larger fleet, say 40, and 30 had winglets, then there might be
an effort to keep the winglets on longer legs, or on SNA flights, but the way they are routed usually means that
they end up on at least a couple of long stage flights a day anyway.

That's kind of what I thought. I presume it's a scheduling nightmare to do so.

When we first started seeing wingletted -700s here, they were routed just as they had been before, namely for maintenance considerations. I can't think of any that were routed for fuel savings, since, that aside, the aircraft still have to end up at certain overnight points for maintenance work, or be in a position to the next night or two...

Thanks for answering my question. I happened to be on the train going from terminal D to the main terminal at LAS witht he piltos who brought us in, and asked them as well. Both of them said that it wasn't something they ever really thought about and said on the longer legs they have flown that by and large they have seen the wingletted airplanes. They also said though that it could be purely coincidence.

I know a larger European airline that operates a mixed winglet and non winglet 737-800 fleet. While not always posisble, there are certain longer haul or performance restricted legs that the carrier "attempts" to schedule winglet aircraft on from its hub. As more and more of the fleet gets winglets this will obviously get easier to accomplish.

Well, today that's certainly true. I mean, you're alot more likely to see a -700 on a MDW-LAX or BWI-PHX flight than a -500 or a -300, not just for fuel savings, but for getting the thing off the ground issues.

Perhaps the advantage of winglets can be fully realized on a B757 from TXL to EWR or B738 from IAH to ANC. However, those are the extreme examples of situations where the aircraft capabilities are stretched to the limit.
