I was on WN flight 1778 on Saturday (9/20) from LAX-PHX. We taxied to Rwy 24L but didn't stop at the threshold of the runway. We continued to taxi about 2,000 feet down the runway (at taxi speed) and stopped at the #8 marker (which is about even with T3.) We waited there for about 30 seconds and then spooled up and intiated the takeoff roll. I have never experienced a takeoff where we taxied down the active and started the take off roll 2,000-3,000 feet down the runway. What would be the reason for this? The load was fairly light and the weather was cool (high 60s low 70s) so we didn't need a lot of runway, but I don't understand why we would taxi down the runway and start our roll that far down. If we needed to abort the takeoff or something, it seems that additional 2,000-3,000 feet would be extremely valuable. Thoughts?

I would think the pilots would have recalculated the V1, VR, and V2 values given the taxi down the runway and shortening the takeoff roll, so I don't think safety is an issue. It does seem strange that the pilots did not hold short. It could have saved them a little bit of gas.
Quoting Ikramerica (Reply 1): The 737 does not need anywhere near all of 24L, especially on a cool day at low altitude, so that is not a real concern.
I was more curious as to the reasoning behind starting the takeoff roll down the runway a couple thousand feet. I could understand if we were taxiing to the runway but didn't need to use the entire length, so to conserve fuel, etc. not taxi the full length. But WN is located at T1, so we were already at the end of the runway.

As Aaway mentions there is some work going on that has limited 24L availability.
Basically the first 2350 feet of 24L is closed leaving 7921 feet avaialble.
In addition the runways ILS and localizer is also out of sevice and landings are prohibited on 24L. This work will continue thru mid October.
From the desert to the sea, to all of Southern California
Depending on the ATC crew, ground traffic and flow time (if you have one) you'll either get there via your route or via D and E Taxiways.
Most flights are able the E10 departure, however there are a few carriers that require a full length departure. In that case more flights are being sent on the south route to 25R. AA Eagle for SOME reason is unable to accept the 24L at E10 and are going to 25R and 24R. However, during the busy times there is quite a wait for 24R due to 4 mile spacing on final.
I know Alaska is loving the E10 departure! All they have to do for the most part is taxi 20 feet and they are on the runway.
