I just recently booked airline tickets for Delta flights. I did it over the web. My fiance hates planes, and likes exit rows the best because of the extra leg room. When I booked online, I was able to select exit row seats. Since I selected exit row seats, I had to confirm that we met the requirements by clicking some agreement button. Also, we had previously signed up for the frequent flyer program, but we are no where near any level so I don't think that played a factor for us.
