This week’s issue of PlaneBusiness Banter is now posted. This week’s issue is one of those “kitchen sink” issues. First we peer into the financial reports of the four largest airline pilot unions — ALPA, APA, SWAPA and USAPA — spurred by my wonderings about just how much the US Airways’ pilot union, USAPA, is paying out in legal fees. Boy, did I open a nice big Pandora’s box. Who says we only have to dissect the financial statements of the airlines?

Then there is American Airlines. No, the airline is apparently not in talks to do a deal with Mexicana, even though press reports south of the border indicated otherwise over the weekend.

Meanwhile, tomorrow is not only the day that American Airlines announces its first quarter loss. It is also protest day for American employees. Concurrent with the airline’s executive level bonus allocations, the Association of Professional Flight Attendants are going to be protesting — and I would bet there will be some other airline employees contributing to the effort.

On the corporate travel front, American filed suit against Travelport and Orbitz last week. They even dropped the “Sherman” antitrust bomb in their filing. Yep, American thinks there is some anti-trust issues here. Travelport and Orbitz, not surprisingly, think this is merely a play for leverage.

Speaking of earnings, we have a line-up of heavyweights on Thursday, followed by another heavy day next Tuesday. We get you up to date on analyst expectations and reporting dates.

If it is time for first quarter earnings, then Proxy Statements are also in the mix. Those are those horribly confusing and hard-to-figure out SEC filings that tell us just how much the top executives at the airlines took home in compensation during 2010.

Southwest Airlines filed their proxy statement last week, and, well, let’s just put it this way. Remember when the airline used to have the lowest top-tier compensation levels in the industry — and they made a big deal about the fact this was the case? And they were proud of the fact? It’s not the case anymore.

Oh, we talk about that, we talk about how airline stocks did last week, we talk about the TSA’s patdown of the six-year-old, we alert you to a museum collection of air sickness bags, and we talk about a lot more — in this week’s issue of PlaneBusiness Banter.
