I needed to go on a trip cross country very cheaply and to my surprise Delta Airlines did the job for me. I usually fly with Southwest because of their prices but this time Delta had them beat. Occassionally, you'll get a great sell with Delta and when you do I recommend you go with them. Delta Airlines provided great customer service and made my trip very comfortable. It was very easy to check in with them online and you could choose your seating assignments online.
The overall flight was very nice due to the fact there was in-flight entertainment. The movie and music selection wasn't the best but atleast it was something to listen to. The only downside about Delta was the food they offered was nothing to write home about. It seems like airline food is going downhill. I guess that's to be expected due to the cheap flight prices. However, Delta Airlines took me where I needed to go and my flights were always on time so you should give them a try too. In the future I will look at them when looking for flights.
