Amen to jarnold's post. I was worth well into five figures to Delta last year, with travel companions who followed my choices adding at least as much again. This was not a one-shot deal: I've been some level Medallion, usually Royal/Gold, every year since the 80s. I wrote to Delta to protest the change and got a form letter brush-off. I am now 100 percent on American. That's over $25,000 in revenue per year moved. In addition, I'm rewriting five examples in the next edition of my business school textbook from Delta to AA - that's 60,000 students who will study free PR for your competition. Delta, are you listening? Do your bean-counters have ANY idea what a long-term business relationship means, and how easy it is to kill it?
