I just bought Delta tickets for a cruise in December. I thought they were very high at $276.90 pp/rt from Knoxville. It is a direct flight, though, which is WAY worth a little extra $$ to me. The only other airline that flies direct from here is Independence and they are in financial trouble too. The same direct flight I bought from Delta was even more expensive on the "low-fare" airline!! Go figure. I kind of decided that fuel and gas prices are only going up, so I'd better book now.
