The next phase of Boeing’s 737 Max 10 certification, Alaska Airlines’ purchase of Boeing jets, the effects of sanctions on airlines, the discontinuation of Avelo Airlines’ deportation flights, and the acquisition of Sun Country Airlines by Allegiant.

Boeing’s 737 Max 10 has entered the second major phase of FAA flight testing, Type Inspection Authorization (TIA). An outstanding design change for the Max 7 and Max 10 engine anti‑ice system has led to certification delays. The core issue is an engine anti-ice design that can overheat and damage the composite engine inlet structure if left on for too long in non-icing conditions. Regulators consider this an unacceptable hazard. The problem affects all Max variants, but it is being treated as a hard certification gate for the Max 7 and 10.

Alaska Airlines is ordering 105 more Boeing 737 Max 10 jets (53 new orders, and 52 exercised options) and exercising options for five 787-10 Dreamliners. This reserves production slots for future airline expansion. Alaska Airlines expects FAA certification of the Max 10 this year, with deliveries scheduled to begin in 2027. The new order includes options for 35 more 737 Max 10s.

A sanctioned country like Iran can’t buy new aircraft, engines, or OEM spare parts and components. Keeping the fleet flying, or just keeping a fleet, becomes difficult. Reportedly, more than half of Iran’s estimated 330 commercial aircraft are grounded. The Iranian fleet is composed of old airframes and supported by scavenged aircraft, parts, engines, and avionics smuggled into the country.

The airline says it will stop flying deportation flights for U.S. Immigration and Customs Enforcement. In a letter to employees, CEO Andrew Levy said, “We moved a portion of our fleet into a government program which promised more financial stability but placed us in the center of a political controversy. The program provided short-term benefits but ultimately did not deliver enough consistent and predictable revenue to overcome its operational complexity and costs.”

Avelo is returning six of its Boeing 737-700 airplanes (they have 8) to focus on the more efficient 737-800 airplanes (they have 14) and said it will close bases at North Carolina’s Raleigh-Durham International Airport and Wilmington International Airport, though it will continue to serve those cities.

Avelo chief executive Andrew Levy told FlightGlobal in September that the airline plans to receive its first E195-E2 in early 2027 and for deliveries to continue into 2032. It considers the incoming E-Jets well-suited for smaller, niche markets that major US carriers avoid.

Low-cost leisure airline Allegiant announced it will acquire Sun Country Airlines in a deal that values the stock and cash transaction at approximately $1.5 billion, including $400 million of Sun Country’s net debt. The Allegiant brand would continue, with the two carriers operating separately until obtaining a single operating certificate.
