While slanted against DL, the article contains some praise for DL and some criticism for NW.
I think most intelligent people would be able to sort out the details and distinctions.
Some of its criticisms of DL obviously describe service losses that are felt, not just in MN, but across the system.
As a legacy DL flier, for almost 40 years, I see the article describing losses that legacy FL folks have felt too.
No mention of unions, though, so let's dispel that red herring.
