I have been with Allegiant for almost 9 years and have to say that I have never been yelled at from a dispatcher or MX. I have never flown an aircraft I thought to be unsafe, I have never been pressured to fly broken aircraft or not to record an issue in the MX logbook. The most MELs I have ever seen was 6. The negative Allegiant people who say we fire Captains for an emergency evacs are just wrong. I have had to evac 155 pax plus crew on a runway at Allegiant. I was not fired or disciplined for my actions because my First Officer and I used good judgement in our emergency. Captains must evaluate the need to get out of an aircraft in a hurry, is there a danger to staying in a cabin with no fire and no smoke? Smoke coming from a breather on a engine is not a danger to pax inside an aircraft. The Captain that was fired had used poor judgement in his evac order in my opinion. He claims that it was necessary to evac asap but he lands and then exits the runway, why would he take the time to do this? He then waits 7-8 mins on a taxiway without actually seeing smoke in the cabin as CFR inspects the aircraft for signs of fire or smoke. Yes the JT8D will smoke from the breather this is normal. Ever seen the CFM56 after shutdown? It smokes like crazy but I am not throwing people down the slides for this. Why would he wait 7-8 mins to evac the plane if it was necessary to get out right away? So he thought there was a need to get out quickly because he thought there might be a smoke issue at the rear of the aircraft, so he orders an evac but does not specify which exits to avoid. You don't send pax towards an exit if you believe there was a safety issue. To top it off this "great Captain" with 100 pic in the 80 goes to Las Vegas with an attitude that he was right no matter what. Guess what he never ran the emergency evac checklist such as shuting down all engines, APU and setting flaps to 28 degrees. He got fired this is correct, I am glad this weak Captain is gone. The issue I see with Allegiant is the quick upgrade to Captain for some with little to no no 121 PIC time.
