There's a great Modern MBA YouTube video on this very subject: https://www.youtube.com/watch?v=rslcr774JXM https://www.youtube.com/watch?v=rslcr774JXM Legacy airlines have done a fantastic job responding to the threat of low-cost airlines, at least in the US. I think that most of low cost airlines' business tactics are easily reproduced by larger carriers, and as low cost airlines scale up they face extremely similar cost structures as legacy airlines. If you really want the Spirit Airlines experience you can get yourself a Basic Economy product and end up with a very similar product and price point but with a much more reliable service and robust route network. Obviously, Kirby's analaysis is highly biased but that's why I recommend Modern MBA's take as an alternative.
