You have to look at more than just the past Eagle Fly.

The present
*Quarterly reports have just been posted.

*Eagle was announced for sale right before Compass and Mesaba were sold.

*A new president at American and Eagle has been announced.

I don’t know but I would guess at 3 reasons why they are announcing the sale of Eagle.
1.) Fluctuate stock price before quarterly reports so keep people can keep bonus.
2.) Threaten APA that AMR is capable and serous about getting around scope.
3.) They see an opportunity to grow a company in hopes of a sale later. How much is Mesa worth?
