My experience with Southwest has been nothing but phenomenal which is why they are my preferred airlines.
The smooth ease of traveling safely to all destinations of course is a BIG plus but the smooth easy of the whole process is what makes me happy. No checked bag fees, frequent flyer miles, great snacks and beverage options. Wifi option in the air with free TV stations. Many direct flight options. Many times at a VERY low price. Matter of fact I booked several trips that were direct flights to Dallas for $88 round trip. SW flies almost everywhere providing an outstanding level of service when your in the air and off the air.
