I've been here 4+ years, and I've never seen anything I would consider unsafe. I've never felt pushed to do anything unsafe. I've never seen mechanics intentionally cut corners. As said before, retiring the MD80 eliminated most of the issues. The Airbus program was always a different airline. Don't forget, it tattles on you.
I wouldn't fly for an airline I thought was unsafe. I'd absolutely put my family on any of our flights. In fact, the scrutiny we have gotten (not all of it fair) has probably made us a lot safer than many airlines.
What scares me is some of the regionals with a 2000hr PIC and a 1000hr SIC flying a CRJ200 or ERJ145 held together with speed tape and deferral stickers in crap weather and complex airspace. But nobody's talking about that because I guess Allegiant is an easy target.
