Airframe story
N633FR is a Frontier Airlines Airbus A321-271NX, construction number 11731, built in 2023. It wears Frontier's animal tail livery, with a photo caption identifying the character as Stewart, shown on both sides of the aircraft as a Red-Billed Streamertail design. FAA records show Bank of Utah as trustee registering the aircraft from 2023, a structure the airline has used for financing across its neo fleet. Over the observed year, Stabilator logged 1,288 flights and 2,399.7 hours on this airframe, with stops including Tampa, Atlanta, Las Vegas, Denver, and Philadelphia. No reporting points to any conversion or retirement, so the jet appears to remain in routine mainline service with Frontier.
Livery guess: Frontier Airlines animal tail design, character Stewart (Red-Billed Streamertail). Photo captions identify the tail art on this specific airframe as Stewart, a Red-Billed Streamertail, shown on both sides of the aircraft
