Allegiant Air (G4, Las Vegas Harry Reid) has confirmed it will accelerate its McDonnell Douglas fleet retirement plans with its remaining forty aircraft of the type to be gone by the end of 2018.

In a 3Q17 filing, the Nevada-based ultra low-cost carrier said the move had now garnered board support.

"This is one year sooner than was previously expected," it said. "A hearty 'thank you' goes out to the members of our fleet team, who through hard work were able to source enough used A320 aircraft to make this happen. This is the end of an era for our company. The ‘80’ has been critical to our success and growth for the past 15 years - it will be missed."

Allegiant operates thirty-five MD-83s and five MD-88s which together average just over 27 years of age. As previously reported, Allegiant will phase out its fleet of two B757-200s by the end of this year.
