Well, it’s not usual to see 2 posts in a day. But...it happened.

Summary of Allegiant Air:

Allegiant Air (usually shortened to Allegiant) is a major American airline headquartered in Las Vegas, Nevada. The airline focuses on serving leisure traffic from small and medium-sized cities which it considers to be underserved, using an ultra low-cost business model with minimal inclusions in fares and a greater number of add-on fees. Allegiant was founded in 1997 and is wholly owned by Allegiant Travel Company, a publicly traded company with 5,600 employees and over US$2.6 billion market capitalization in 2016. The airline is the fourteenth-largest in North America.

Aircraft in real life:

Allegiant Air used to have 6 Boeing 757-200’s. One of the being N901NV. The plane had been in service with Allegiant before being retired in August 31st of 2016. N901NV and all other of Allegiant's B757-200s entered commercial service in 2011 from Las Vegas to McAllen and Rockford. But the real reason for the sub-fleet was for Hawaii service. Hawaii started in the summer of 2012 when Las Vegas to Honolulu and Fresno to Honolulu took off. For Allegiant, Hawaii was a big, different, complicated, costly, and ultimately short-lived experiment. Likewise, its B757s, which all ceased being used in October 2017.
The 26.8 year old 757-200 [N901NV] was used by:
- Britannia Airways in May 1992 as G-BYAD
- ThomsonFly in Nov 2005 as G-BYAD
- Thomson Airways in May 2009 as G-BYAD
- AerCap in Dec 2009 as N963BV
- Allegiant Air in Apr 2010 as N901NV
- Air Finland (Leased from Allegiant Air) in Mar 2011 as OH-AFL
- Allegiant Air (Returned from lease) in Apr 2012 as N901NV
It was stored at Stuttgart in 31st Aug 2016 and was broken up in Feb 2019.
