Allegiant Air (G4, Las Vegas Harry Reid) has again delayed the induction of its first B737-8-200, from August to October, ch-aviation research has revealed.

The US ultra-low-cost carrier, which initially expected to introduce the new aircraft type in March and then in August, has now scheduled its first flights for October 2. The ch-aviation schedules module shows Allegiant will operate services from Orlando Sanford to Indianapolis International, Knoxville McGhee Tyson, and Peoria International.

The next day, it would begin flying from Orlando Sanford to Akron Regional, Allentown International, and Greenville/Spartanburg International, and on October 4, it will start services to Roanoke Woodrum Regional and Tulsa International.

In May, Allegiant Air expected to add only six B737-8-200s, all arriving in the year's second half, and closing the year with 126 aircraft on its fleet. It was initially expected to receive 12, but the ongoing Boeing quality issues and reduced output forced the ULCC (and many other companies globally) to adjust its fleet growth plans accordingly.

ch-aviation has reached out to Allegiant Air for comment. The airline said it expects to receive its first MAX in the coming weeks.

Allegiant Air is set to receive twenty-six B737-8-200s and twenty-four B737-7s (with options for 80 additional airframes), joining and substituting the Airbus based fleet it currently operates, composed of thirty-five A319-100s and ninety-six A320-200s.
