people vote with their wallets, right? So, if corporations and regular guys like me are willing to pay extra for a premium product, then DL must be doing something right.
Everything I've heard about UA's cheap ugrades comes at a price.
Plus, there is a huge product gap between what DL has and what UA has. Personally, I'd rather be on a 747 upperdeck with a 1 - 1 config then anything UA can throw at me. You pay for what you get.
