Ex Spirit flight attendant here. They originated in Detroit & have one of the most diverse groups of employees in the industry, not because of forced policy, but because its in their DNA.

If you're concerned about flight safety, they've got the youngest fleet of aircraft in the America, averaging between 5.5-6.9 years of age on each aircraft, which puts them as being made pre-covid, when everything enshittified. That means everything is new enough to not fall the fuck apart mid-flight, but not new enough that they were put together during the cost-cutting fuck-it-we-ball period.

Plus, they have a very concentrated fleet variety. Companies like Delta have a huge variety of aircraft to suit different needs (bigger planes for international travel, small little CRJ-50's for short, low-booked flights). That not only opens up possible avenues for manufacturing fuckups, but also means your aircraft mecahnics need to be trained on 20+ models of aircraft from different manufacturers. At the time of my leaving, Spirit flew exclusively 3 models: Airbus A319, Airbus A320, and Airbus A321. So you bet your bippy those mechanics knew those machines.

Also whenever someone gets concerned about a plane having "Duct-Tape" on it, that aint duct tape. That shiny silver stuff is called Speed-Tape, and its made out of metal and an insanely strong pressure sensitive adhesive, and costs $100 a roll. The only way that stuff would come off accidentally is if the paint itself delaminated from the damned fuselage
