Last week we had some unseasonably rainy weather in southern California. While it wasn't enough to make a dent in the on-going drought, it was sufficient to snarl air traffic for a few days. A number of our controllers wanted you to see these shots. While they don't tell the whole story, you can certainly get the idea.

This follow-on to Friday's shot gives a better view of what was happening to create the shot I showed you before the weekend. Essentially, each airplane is waiting on the one in front of it, and the key player to the whole mess is the American heavy seen at the far left. It's pulling onto gate 48B, or at least is supposed to be. The fact that somebody had time to go grab my camera and take these shots tells us that the tug has most likely stopped partway onto the gate -- probably because some piece of ground service equipment is in the way, the jetway is not in the correct position, or the ground crew isn't in place to receive the aircraft. Everything else is a domino effect: the American Eagle CRJ is waiting for the B777 tail to clear the intersection; the Alaska is waiting for the Eagle; the US Air coming off the runway is waiting on United who is waiting for Alaska; the Delta E-jet on the left is waiting for US Air while the Delta E-jet on the right is waiting for everybody.

As many of you have noted, one of the aircraft in last time's shot is not a regional jet. Let's see that shot again:
There is a hint in the photo: one of the airplanes is marked "Delta Connection" and the other is not. Many of you caught that the airplane on the runway, which is the one facing to the left in the picture above, is in fact a mainline Delta B717. The Delta Connection airplane really is an RJ, in this case a CRJ9 operated by SkyWest.
To some of you, the B717 may look very familiar -- though you don't remember it as a Boeing product. It takes very little imagination for this to look like the DC9's almost-identical twin. Which, in a manner of speaking, is pretty much what it is. The B717 is essentially a shortened version of the McDonnell Douglas MD-90 (which Delta also flies, although not into LAX right now). This model was to be called the MD-95, but Boeing took over before it went into production. The MD-90 was a revised and improved model developed from the MD-80, and the MD-80 was itself an improved version of the DC-9. So in a real sense, this B717 is the final iteration of the DC-9.
This is not the first aircraft to be labelled a B717; prior to this a shortened version of the B707 wore the name for a short while before becoming what is now known as the B720. Before that, there was another model 717: the aircraft now known as the C-135 or KC-135. Boeing's internal model designation for the C/KC-135 series was the model 717.
This is not the first time we've seen B717s at LAX. It's been years, but we used to have Midwest B717s. Here's one from May of 2008, along with a Delta MD-88:
Before Midwest, AirTran operated B717s at LAX for a short while. The B717 is not a long-range airplane; LAX to Atlanta was too far, so they went into DFW. This was before AirTran added the B737 to their fleet; once those aircraft came online, LAX to Atlanta nonstops became a reality, and the AirTran B717s left LAX.
Except now they're back, flying for Delta. If you look closely, you can see that the Delta B717s all have tail numbers ending in "AT"; these were AirTran airplanes until Southwest took over AirTran. Southwest opted not to add a second aircraft type to its fleet, and so the B717s were sold off. They didn't have to go very far, though: AirTran and Delta both used Atlanta as a home base.
Since early this month at LAX, Delta is using the B717s on regional routes, mostly up and down the coast -- on routes that have often been served (and in most cases, still are) by SkyWest CRJs and/or Compass E175s. The B717 is bigger than the largest of these, the CRJ9 -- but just barely. I won't go into comparing all the specifications, although I will give you links for them below. The most important (from an airline perspective) number is passenger seating: Delta's B717s are configured for 110 passengers; the CRJ9s that SkyWest flies for Delta are set up for 76 passengers. Going the other direction, the next largest airplane in the mainline Delta fleet are the Boeing B737-700 and the Airbus A319. These seat 124 and 126 passengers, respectively, but neither of these are seen at LAX very much.
Since this has become pretty much an entry about Delta, I'll close with one more photo from the archives -- one that features three Delta aircraft that are no longer seen at LAX:
