Why Delta Doesn't Get It

I was flying from Atlanta to Dayton, OH to visit a client and was sitting in first class. A couple on their honeymoon came on board. He was in the Air Force. For some reason, the woman got upgraded and ended up sitting next to me. Her husband was in coach. Half of the first class seats were empty. The woman asked the flight attendant politely if her husband could move up and sit with her. The flight attendant said she wasn't in charge and would have to check. She ended up doing nothing, so I decided to help the woman out and motioned the managing flight attendant over. I explained the situation. After 5 minutes of conferencing and furiously looking at paper, he came back and said there was nothing they can do. Mind you, this was an hour flight; at most this was going to cost a glass of wine. Here we have a patriot for our country on the plane, a newly married couple - imagine all the goodwill that would generate. Instead, Delta chose to follow some stupid rule, alienate passengers and show once again why the airline industry is losing so much money. They don't understand the customer, and obviously don't care enough to make the extra effort. As a frequent flyer, I found this to be very disturbing. When will the airline industry wake up and deliver an experience that actually helps the customer?
