Cons: "4 hour delay"

Pros: "Great flight"

Cons: "After a delay of about an hour on a very full flight the gate agent asked for volunteers to check their rollaboard suitcases. The gate agents then allowed those who checked their rollaboards to board before Zone 1,which was fine. However, a bunch of people without gate check stickers on the rollaboards were also allowed to board before Zone 1, which was aggravating. There was a long delay on the tarmac, during which we had to pull back to the gate or to a maintenance area before we finally took off. When we arrived in Vegas there was no gate for us to pull into, which led to another long delay of an already long and delayed flight."

Cons: "at last minute itinerary was changed.. instead of routing through Brisbane, was now routed through Sydney. Flight from Sydney to LAX was delayed by 4 hours, then missed flight LAX to LAS... overall long delayed arrival. Checked the route through Brisbane, and those flights we're all there, departed and landed all on-time... so wondering what the reason was for the change of the itinerary without a cause (no cancel or delayed flights through Brisbane)"

Pros: "Departing"
Cons: "More than 4.5 hrs in taxi waiting to take off. Due to “few rain” and after 3.5 hrs we needed to refuel when we were about FINALLY close to our turn for take off. Horrible service by DELTA. Never flying again with them"

Pros: "The wait"
Cons: "The screen didn’t change in time"

Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"

Cons: "The pilot was a Daredevil"

Pros: "overall flight great,pleasant trip, courtious well informed crew"

Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."

Cons: "Tv"

Pros: "Nice flight attendants"
Cons: "Freezing flight."

Pros: "The chekc in person was very helpful."
Cons: "The plane was too hot and the pilot did not accommodate the passengers request. More than just me made the same request."

Pros: "The flight crew was so polite and willing to help."
Cons: "The boarding process needs to be looked at. Maybe creating better zone style lanes might work, it's always a hassle and always a pain in the a** trying to navigate my way to the boarding door."

Pros: "In flight entertainment was nice to have, and the rebooking was easy. Flight crew was great."
Cons: "Flight arrived a few minutes late and had to run to the next terminal to catch a connecting flight. Arrived in time, but the gate agent closed the gate early, causing me and several others to be stuck in ATL overnight. Ended up having to pay for a hotel and rental car that went unused."

Cons: "I didn’t like having to pay for bags and headphones."

Pros: "Service was great. Regular drinks and snacks."

Pros: "Great"
Cons: "Too many announcements"

Cons: "I have traveled with my luggage plenty of times through airports and the flight from washington to jacksonville, my luggage came back to me cracked and broken. I was surprised that Delta handling was worse than any of the cheaper flights I normally take and will not be checking any baggage with Delta again."

Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."

Pros: "There flight was over booked. My wife and I were the only two left in the terminal this morning as we watched everyone leave for Las Vegas! I’ll be missing a wedding today frontier! Thank you!"
Cons: "The whole experience was awful!"

Cons: "It would take little effort for the flight attendant to say which terminal the baggage claim is. If she can say the carousel number, she can say the terminal number. Half the flight went to the wrong baggage claim and had to wait in the heat for the shuttle in order to get to the right one."

Pros: "Liked everything just wanted a better seating choice"
Cons: "The middle seat"

Pros: "Nothing."

Once I got in the plane I saw a tennis racket in one of the overhead bins. I'm writting this for two reasons: 1. I'm mad because I paid $45 for nothing. 2. I'm bored because we landed in Austin 30 minutes ago and I'M STILL INSIDE THE PLANE!!"
