Airframe story
N645FR is a Frontier Airlines Airbus A321-271NX, serial number 11954, flying under the livery name "Thunder the Bison." It first flew as test aircraft F-WZMT, with industry tracking recording a test flight from Mobile to Mobile on May 6, 2024, before being delivered from Mobile to Tampa on May 14, 2024. The aircraft is registered to Wilmington Trust Co as trustee from 2024, rather than to Frontier directly. In the past year the jet logged 1,313 flights and 2,479 hours, including an incident in which flight F92407 from Las Vegas to Seattle diverted and landed at Reno. Recent chapters in its movements include stops at KMIA, KDEN, KTPA, KPHX, KCLE (twice), KMCO, and a longer stay at KDEN.
Livery guess: Frontier Airlines "Thunder the Bison" livery. Snippet explicitly names this registration as wearing the Thunder the Bison livery
