I would avoid because if they are cheap with everything does that include their training. If you were a fab pilot would you want to work for say Emirates or Ryanair?
There is no such thing as a "fab pilot". In fact it's when pilots start to think they're "fab" that the problems start. (See #t=13s 😂)
Airlines spend millions on training and certification. Ryanair and Easyjet are ranked first and second for passenger safety in the world (deaths per billion passenger km flown) — neither has ever had a fatality, and Ryanair only pips Easyjet because it's bigger and so zero is being divided by a bigger number. Airlines have to jump through all sorts of hoops to keep their approval to fly in the UK or the EU, and they don't do that by letting pilots knock off training early or have a beer during the lunch break.
Ryanair also has one of the best-maintained fleets because they buy new planes, don't keep them for very long, and have first dibs on the Boeing 737 maintenance facility at Stansted. This also means they ex-Ryanair planes are in demand on the second-hand market, which also makes money for them.
One of the best channels on YouTube is Mentour Pilot, run by a Swedish training captain who goes into the history of aviation accidents and explains how they happened and what the industry then does to stop the same thing happening again. I was never a very apprehensive flyer, but since watching that channel I have become even less concerned, because it teaches you how and why flying is so safe. And he's a pilot for Ryanair.
