always funny when pilots say airline 'x' pays more because they see a few dollars more on a payscale guide.

I'll always argue that we (United) and Delta are close to the same..
When you look at how much you were paid vs. how much you actually flew. (Flight Hours vs. Credit Hours)

I'm good for a few grand a year on middle seat dh pay, then there's other little compensation that all adds up. (Add Pay)
End of the day, number one should be where do you live vs. where are the bases.
Then, what's movement like at the 2 carriers.
Last.. what's the 'attitude' of the 2 carriers.

Personally I think that Delta as a company will ALWAYS make more than we at United.. as a company.
However, I believe WE will always do more of our own flying and have more widebodies than our friends over a Delta. Something to also think about.

Good Luck in your choice~
Always
