Is it possible that airline passengers are experiencing soaring prices and bad service because the number of domestic carriers has shrunk from 12 in 1980 to 4 today — with many cities served by only 1 or 2?

There is a clear lesson in the Southwest debacle about concentration.

Southwest is a niche carrier, and look at the turmoil they created with a system failure.

Now, imagine that was Delta.
