"Identifying Your Aircraft: Is Your Next Flight on a Boeing 737 Max 9?"
The Federal Aviation Administration has approved the Boeing 737 Max 9 to resume flights after an emergency landing incident. United and Alaska are the main U.S. carriers of the 737 Max 9, with plans to reintroduce the aircraft into service soon. Passengers can use booking sites like Kayak to exclude the Max 9 from their search, and airlines are offering flexibility for passengers uncomfortable with flying on this model.
