Another day, another day of carnage for airline stocks. Three in particular, including one notable newcomer.

With Frontier Airlines going into Chapter 11 bankruptcy protection, it’s no surprise that shares here were down dramatically on the day. Shares ended the day down a whopping 69%, on more than five times the normal volume, as the stock ended trading at 48 cents. (It started the day at 1.57.)

Shares of Mesa Air Group also had another bad day. Shares here were down 17%, ending the day at 67 cents. The stock started the day at 81 cents. Market Cap here is now down to $18 million and change.

And finally, we had a notable newcomer to the share sell-off club today — another member of the PlaneBusiness Titanic Watch. AirTran shares were simply hammered today, as they lost 35% of their value, closing at 4.13. The stock opened this morning at 6.31.

Again, volume here was more than five times the norm.

What’s going on here? My guess is that It’s a little thing about credit card holdbacks. The same reason Frontier sought Chapter 11 protection today. Investors apparently don’t like the airline’s cash position, relative to what could happen if the airline’s credit card processor decides to up its reserve amounts for the airline.

Oil? Oil today closed at 110.14/barrel, up 3 pennies on the day.
