I've traveled several airlines in the past but by far southwest is the best. The fares and really low when you can book at least two months in advance. You can check two bags up to 50 pounds per person with no added fee. You can carry on one size limited bag and a personal item per person. Seating is open and the in pre flight instructions are comical. They have very competent pilots who do their best when the weather is poor. I've only been delayed once due to weather. Hands down the best airline for price, flights and employees.
