Here is what Richard Stroker has to say about the flight:
Seats are as comfortable as they get for economy class seating. Seats are assigned by boarding number you receive by checking in on-line. If you read the Southwest website, it clearly states there is no in-flight entertainment so don't expect any. SW is experimenting with in-flight WIFI on select flights. Southwest typically has the best air fares between regional cities. You can also cancel or change a SW flight without penalty or receive credit for airfare to be used with in one year. SW doesn't charge extra for checked luggage unless its over weight or more than 2 checked bags. Book early and check back later for reduced airfares.
