Alaska Air Group has announced that it has modified its existing backlog with Boeing to include ten firm B737-8 orders and six for B737-10s. The change reflects the "recalibration" disclosed in early March, which saw the airline diversify from its previous all-B737-9 backlog.

The modification also includes forty-one B737-10 options.

The parent holding of Alaska Airlines and Horizon Air did not give a detailed fleet forecast in its quarterly report and did not discuss it during its recent quarterly earnings call. It did not respond to ch-aviation's question on whether the order is the conversion of a part of the existing B737-9 backlog or a new commitment.

Prior to the modification, Alaska Air Group had firm orders for eighty B737-9s from Boeing and a further thirteen from Air Lease Corporation. So far, it has taken 20 units, including 14 directly from the manufacturer and six from the lessor. In March, the carrier said it "envisioned" a target fleet of 145 B737 MAX, comprising fifteen B737-8s, seventy -9s, and sixty -10s.
