What you need to know from this week's big aviation conference

A bunch of aviation reporters are braving steaming temperatures this week in Las Vegas to bring us news from an important airline conference. I've been following via social media from the home office, and though I haven't seen big news yet, I did notice some interesting tweets. 

If you're on Twitter, you might consider following some of the people below. They know their stuff.

Here is some of what I have learned:

American Airlines will soon add at least three more retro paint jobs. Of the three, I like TWA the best. What about you?

At every industry conference, Southwest executives assure analysts they won't soon charge for checked bags. This one was no different. Do you agree free bags lead to more repeat passengers, as Andrew Watterson, Southwest's senior vice president of network and revenue management, argues?

Frontier's president says he is not concerned about the high number of complaints customers have made with the U.S. Department of Transportation. Why? Apparently, he thinks his customers are more tech savvy, and thus more likely to complain online, than legacy carrier passengers. I'm not sure I agree. Do you?

An executive with Frontier's main competitor, Spirit Airlines, also blamed passengers. Spirit believes consumers should understand the business model. Travelers save money, but they give up some perks in return.

Virgin America CEO David Cush likes to speak this mind. In May, you'll remember, he said he thought more airlines should charge for carry-on bags. This week in Las Vegas, he complained that the big four airlines behave like an oligopoly.

Cush also hinted Virgin America wants to add A321s to a fleet that now only consists of A319s and A320s.  But so far, it has been unable to do so. Perhaps Airbus won't give Virgin America a sweet enough deal?

And finally, Jetblue CEO Robin Hayes dished a little bit on JetBlue's new Mint business class product.
