This week’s mega-earnings issue of PlaneBusiness Banter is now posted. Subscribers can access this week’s issue here.

What is on the agenda this week? First, we have in-depth reviews of the earnings calls from AirTran, Allegiant, and WestJet.

But that is just the start.

Our first column from this year’s Phoenix Sky Harbor International Airline Symposium discusses a presentation that was made at this year’s event by Adrian Slywotzky, economist, author, and partner with Oliver Wyman — the consulting firm that works with the airport to put on the Symposium.

The subject of his presentation? The airline industry is not the only “no-profit” industry out there. And yes, there are competitors in other “no-profit” industries who have figured out ways to improve profitability. Are there lessons here for the airlines? Yes.

Our second column this week is our first take from the recent US Airways Media Day. Coming just a day after the airline’s earnings call and just a couple of days after the airline said it wasn’t talking to the powers-that-be in Chicago anymore — the airline still managed to give us some information we’d never seen before.

All that plus the manic moves on Wall Street last week, the NMB’s news from today, the DOT’s decision on the proposed slot swap, American’s decision to hold its annual meeting away from the madding crowds, and more. In this week’s issue of PlaneBusiness Banter.
