Delta has warned Wall street that their prediction of a 40 cent/share profit has changed to a prediction of a 70-90 cent/share loss, on the tune of $100 million or more. They also are predicting a poor 2nd quarter.

Apparently bookings are lightening up due to projected upcoming labor problems, and revenues are down due to Delta's almost 3% reduction in flying effective last year.

Now, here's the question: will NW/UA/US/AA be in the same boat here? They all are having upcoming labor issues, and I know that UA also reduced flying.

Which of the carriers has a more 'normal' relationship between with labor, and how are they doing profit-wise?
