sfb is correct. The "Southwest Effect" has been evident in every market WN has entered for 25+ years. Rational prices and affordable full fares lead to a dramatic expansion of traffic for all airlines. Pain for the airlines relying on extortion fares, but benefits for consumers.
Some people believe that WN has artificially lowered fares lately due to their fuel hedges.
Others believe that fares are set by balancing the supply and demand, and that has meant eroding yields and declining RASM for nearly all airlines over the past four years.
I'm a believer in the latter. Predatory pricing exists only in the minds of some people. It doesn't exist in reality.
