Southwest Airlines largest low-cost airline in the world.

  If you are residing in the southwest region of the united states Arkansas, Colorado, Louisiana, Montana, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, Utah and Wyoming.   I strongly recommend you flying with southwest airlines it has daily more than 200 flights operation to major destination in the US. Southwest airline does not follow a hub system.   so you don't have to go through a certain route all the time rather than it follows a spoke system, due to which you might find flights flying non-stop between many airports. Surprisingly Southwest airlines offer ultra-modern low fares designed for every type of flyers whether if he/she is a regular passenger and fly on a bi-weekly basis or once in a while every year.   A few of the things I like the most about southwest airlines is they offer two checked-in bags free of cost. Seriously two checked-in bags free to any destinations southwest flies into that's amazing right. You should have seen the grin...
