I travel a lot for work, so I agree with the previous poster's very accurate assessment of the airline industry: "a pretty lousy lot".
I laughed at the quote above, not because of her situation, but because I was in the same boat the last time I was on Delta. The guy in front of me reclined ALL THE WAY back (and then some, I think). I said to him, "Sir, I'm going to have to ask you to sit up. If you recline any further, you're going to owe me dinner. "
My biggest complaint with Delta is that out of all the airlines I've used, they are the ones who I've had the most uncomfortable seats, missed flights, cancellations, delays, lost luggage and such - and ended up being one of the most troublesome of the "lousy lot". That just could be my luck, too...but be aware that any travel through Atlanta may cause issues.
No matter which airline you choose, the best we passengers can hope for is to get to our destination on time and in one piece and that our flight attendants are not having a bad day. My advice: Just keep your thoughts on what awaits you at the end of the flight!
