Allow me to expand on my comment. The main point I meant to make is that everybody has a one and only worst airline based on their experience. My comment was not specifically about Delta. My own worst experience with Delta had nothing to do with a travel experience. It was that I had failed to travel with Delta for a 2 year period, and Delta deleted 50,000 miles previously accumulated in my frequent flyer account. No notice, no warning, no offer to fly with them again.

That was just extreme poor marketing and stupid. They lost me. The reason for the lapse was that Continental met my needs more. But I would have gladly gone with Delta if they had asked, or if they had even so much as warned that they were about to take such drastic action.

But my point was that each person has their own worst and best airline based on their own experience. Mine is Delta for that loss of miles.
