Pros: "I am 6'6" 300 pounds ... So I regularly book first class for trips over 2 hours in length ... Delta remains my #1 choice for both value and overall experience in first class. The difference between Delta and all other domestic carriers is just overwhelming. United and American/US Air could learn a lot from Delta. I could have flown this trip direct on United, but chose to fly through Atlanta on Delta for less money and a better experience from the baggage check to the gate to the in-flight experience."

Cons: "If you don't pay for the premium seats, the legroom is pretty tight. I'm only 5'8" and I felt it -- if you're 6'+ you better pay for it. This aircraft had screens, but not individual ones so you're stuck watching whatever sitcom replay they pick, although there is a moderate selection of other music. I've been on a newer aircraft with the in-seat power and interactive screens so I know how good it can be, so this was a little disappointing."

Cons: "My wife and I traveled with bicycles packed in standard boxes and got hit with a whopping $230 charge per bicycle out of the blue. We were expecting no charge because the bicycles were our only check-in baggage for the trip. Couldn't believe the lack of transparency with which we got hit with this charge. Qantas, Air New Zealand, and other airlines we've taken bikes with us on our flights have charged nothing when we traveled in the same fashion. So, if you are a bicyclist traveling with your bicycle, I'd avoid the United-Lufthansa duo."
