I have consistently flown AA for 10 years. This year I am at 145,000 actual flight miles (all paid coach tickets) and hit Exec. Platinum the hard way. Since I live in the Upper Midwest I also fly Northwest extensively (Gold with 45,000 miles YTD).

All of my AA flights are connections originating on American Eagle and then the treck from G to K or H at ORD.

In my view, American is my choice simply because of Professionalism. Their phone employees are always very professional, knowledgable and helpful. Most Flight attendents as well. Nothing extraordinary, but very consistent and professional.

When flights are delayed or cancelled, it never is easy. But I have seen AA almost always treat me with dignity and respect. I always get the sense they are "trying".

My other carrier, Northwest, is literally a 3rd World carrier in comparison to AA. Old, unionized employees. Filthy, old planes and such an unprofessional, unpolished image from all aspects of the organization.

My vote goes to AA.
