Airline Stocks Still Are Undervalued

First off, if you look at a 10 year history of share prices for Delta, Southwest Airlines and others,  you will see that prices declined and stagnatedmfor these shares for quite some time.  The shares finally bounced back a couple of years ago with staggering returns, but if you annualize those returns over the last 10 years, you will see that the results are more modest.  Add to this the fact that these companies are recently generating huge profits, and you can possibly draw the conclusion that I have.  That is, that they can run much further.
