The sad thing is UA stock is still up 25% YTD and 55% over the past year. While DL, AA, and WN are up more, it's going to take a rather sharp dive in those numbers for investors to push him out.

By comparison the S&P is up 5% YTD and 20% over the past year - so he's still beating the S&P by a healthy margin and really that's all that matters in the end unfortunately
