Airframe story
N622FR is a Frontier Airlines A321-271NX known in public tracking under the nickname Buttercup The Utah Prairie Dog. Records show it was delivered on 15 July 2023. The aircraft is part of a broader Frontier A321neo order, which included an additional 91 A321neo aircraft announced for delivery from 2023 to 2029. On the FAA registry it is held by Bank of Utah as trustee from 2024, a structure shared by sister ship N624FR, also held by Bank of Utah as trustee. In July 2026, a scheduled Frontier flight F9 3567 from Cleveland to Dallas/Fort Worth using N622FR diverted to Oklahoma City instead of completing its planned route, though the reason was not publicly disclosed. Its most recent tracked activity places it at Orlando (KMCO).
Livery guess: Frontier Airlines - Buttercup The Utah Prairie Dog animal livery. Public tracking identifies this registration with the named livery nickname.
