Flew Southwest, There were dings, but I had to work and by the time I booked the tickets were around a thousand dollars for three! I will never fly Southwest again. All that time spent waiting for a ding, then not being able to jump on the reduced price, the preboarding. We were in Group A each time but our first flight was delayed, ran for our connecting flight just as the were boarding the last group, split up from my family, sat in the middle of two large men, as did my dd and dh. The crew down were pleasant but not on the way back.
