Yesterday, Alaska Airlines announced an expansion of its order book with Boeing by ordering 13 737-900ERs, a new aircraft type, along with two 737-800s, which currently make up the largest part of Alaska’s fleet. Alaska hasn’t made a final decision on the configuration of the aircraft, saying they will seat between 178 and 184 passengers. That’s 6-12 more seats than existing 737-900s, so I’d reckon that’s one or two more rows of economy. For comparison’s sake, Alaskas 737-800s seat 157.
Here’s a chart of the previous and new delivery schedule through 2014:

A little bit of background on the 737-900 – Alaska was actually the launch customer for the type, taking deliveries of twelve aircraft from 2001 to 2004. Overall, the -900 wasn’t all that popular with customers, with only 52 were delivered.
In 2005, Boeing launched the new 737-900ER, which offered multiple improvements over the original type, such as more passenger capacity thanks to more exits and a flat rear pressure bulkhead, increased maximum growth takeoff weight, and additional range (which varies based on options for auxiliary fuel tanks). The aircraft entered service in 2007 with Lion Air, and so far nearly 300 of the type have been ordered. One can view the aircraft as Boeing’s closed replacement to the 757-200, and the closest competitor to Airbus’ A321.
So why does this airplane make sense for Alaska? Well, let’s look at an example in Boeing’s press release – Seattle to Orlando. Right now, it appears that the largest aircraft Alaska can toss on the route is a 737-800, and the airline operates two flights per days with that aircraft type. Let’s say Alaska wants to increase supply because demand is strong. Well, that means a third flight needs to be operated with a 737-700 or 737-800, and that comes along additional costs like additional flight crew. Those costs could make an increase in capacity uneconomical. But, if an 737-800 is an upgraded to a 737-900ER, then maybe the additional capacity makes sense, especially as the 737-900ER should have lower unit costs than the 737-800 (partially driven by less fuel consumption per seat).
The 737-900ER should also offer more attractive costs than Alaska’s existing 737-900 fleet. One way I like to look at it is weight. The 737-900ER’s operating empty weight reported by Boeing (based on a base two-class configuration) is very slightly (less than 100 pounds) lower than that of the original version, and plus it can seat more passengers. So one way to look at is that there is less empty weight per passenger on the -900ER. Fuel burn per seat is also lower on the -900ER than it is on the base version.
Meanwhile, other fixed costs are better spread out thanks to the 737-900ER when compared with a 737-900 or 737-800. For example, two pilots are still required, and the seating configurations of the 737-800, 737-900, and 737-900ER all require four flight attendants as per FAA regulations. Assuming that Alaksa staffs all of the aircraft types with the same number of FAs, that means labor cost is more effectively distributed among passengers.
Anyway, it’ll be interesting to see how Alaska distributes these. I wouldn’t be shocked if some of them ended up at the high-yield, slot-controlled DCA. Alaska uses slots exempt from the airport’s perimeter rule to serve Los Angeles and Seattle. I was also wondering if Alaska would have the 737-900ERs equipped for ETOPS operations so they could fly to Hawaii. An airline spokeswoman that the -900ER “could be used in certain Hawaii markets, but we have not yet made a decision to order the aircraft ETOPS equipped.”
I’m about to hit 600 words here…how do I tie a bow on this one? I guess I’ll just say I like this move.
