Updated with comments from Alaska Airlines

Alaska Airlines has converted two options for Boeing 737-900ER aircraft to firm orders, bringing its total backlog for the type to 32.

The deal is the airframer’s first firm order in 2014 and was announced at a delivery ceremony for Alaska’s 100th next generation 737, it says in a statement.

“Alaska is proud to fly an all-Boeing fleet," says Mark Eliasen, vice-president of finance and treasurer of Seattle-based Alaska Air Group, in a statement. “The 737-900ER has proven to be an ideal upgrade for us.”

The order is valued at $192 million at list prices, according to Boeing.

Alaska operates 13 737-900ERs and has firm orders for 30, not including the two announced today, Flightglobal’s Ascend Online database shows. It also has firm orders for 20 737 Max 8 and 17 737 Max 9 aircraft, and options for 31 737-900ERs.

The airline says that all -900ERs, including the two additional aircraft, will be delivered by 2017.

Alaska converted five 737-900ER options to firm orders in September 2013, bringing its outstanding orderbook for the type to 31 aircraft at the time.
