I've been using Allegiant for the past 4 or so years. So, this is just my experience with them. I've never had an issue with them. I've been delayed twice so far. Once for bad weather back in Austin, and another because a passenger was really sick. So, can't blame them there. Out of Austin, there's not many options for a direct flight. SW is the the other one. Even with the extra baggage fee, they're less than half what SW is. At one point I thought they were phasing out their MD-80's for 747-200's. But, looks like they're ramping up the 80's again. Down side is they are louder, but I have an OK set of headphones. So, I just put on a movie, and sleep about 80% of the trip. By the time we board I've normally been up for about 20+ hours. And, I normally get a drink at the airport, so I don't buy one on the plan. They don't care if you bring on a drink as long as it has a lid/cap. And, you can't really blame them for keeping people out of the seats that they charge extra for. That's money out of their pocket. But, you can pay for it if they're empty. I've seen people do that before. I've seen the lines in Vegas both ways. Where you can just walk an through with no problem, and where it's a huge line. My last trip a TSA agent told me something that made me happy, and mad. Since I use a cane, he told me I can go through the VIP/handicap line, and bypass all of the winding lines. Wish someone would have told me that a while back. And, they just moved to a new terminal here in Austin. So, the line for TSA screening was really short. I used to have to wait about 30+ min to get through. Down side is it's what they're calling "retro". So, they have a ramp going up to the plane, and no gangway.
