Cons: "naad"

Cons: "I have the worst opinion of the Delta company, when I was flying to Atlanta on October 20 they changed my flight at the last minute I had to leave until my job to take another flight. Just today when returning my suitcase did not arrive they sent it to another destination. I think the company gives very bad service."

Pros: "Boarding was easy, flights on time Wi-Fi available (although I didn't use it)"

Pros: "Crew was very good and nice on the flight"
Cons: "Flight terminal was changed about 30 to 45 minutes before boarding Flight was delayed due to AC problem Configuration of the plane was terrible. Little leg room but the windows did not align with the seats so a window was shared with two rows making it challenging to open or close a window without disturbing the passenger in the other row with whom the window is being shared. No charging outlets in the terminal or on the plane. Plane had no food to offer for purchase. Expected better from Delta."

Pros: "Flight was smooth and flight attendants were nice."
Cons: "Well delta over sells their flights every time and have to buy people out of their seats. This would be fine if it didn't mean that your seats have to be changed last minute and without your knowledge. I choose a window on purpose because I am claustrophobic. I did not pay for upgrade because I was able to select a seat that was a window...had I known it could change I would have. Zero communication just surprise you have a. Ew seat."

Pros: "Very new plane arrived on time no problems"
Cons: "Nothing everything was great"

Pros: "First class crew was great! Smooth ride, arrived early"
Cons: "Lunch option on LAX-AUS wasn't that good (chicken salad or meatballs), also was pretty sparse on the meal itself compared to other airlines"

Cons: "Missed connection"

Pros: "The crew was very nice as usual. A bit too many announcements that ran a bit too long. Other than that great folks."
Cons: "No water on the plane so no coffee and no running water in the bathrooms. They did well trying to accommodate but between that and a calibration issue in the cockpit that had us running late it was not the best delta flight I've been on."

Pros: "Clean plane, good service. on time departure, early arrival."
Cons: "I did not like the way the plane was boarded- people could not get into their seats because others blocked the aisles - so chaotic. Passengers were not being rude to one another, it was simply that the process is poor. Could the zones instead reflect both location of seat and area of plane, so that those with window seats at the back board first, then middle seats, then aisle? That way if aisle seats fill first, seated people are not stepping back into the aisle to accommodate others needing to get a seat in that row, while everyone on the gang way must wait for the aisle to clear."

Cons: "New design of the the plane with side to side bathrooms at the back leaves much to be desired. Those were the smallest airplane bathrooms I've ever used!! I had trouble fitting and I'm not a large person!"

Pros: "What they offer is OK."

Pros: "They did give us the Dane snacks the first class passengers got."
Cons: "Zero additional leg room in this supposed comfort seat. The seat was very narrow and there was absolutely no additional leg room on the flight. I'm tall, so that's what I pay for when I book these flights and none was provided."

Pros: "Took care of us, gave us snacks and drinks, and pillows and blankets"
Cons: "Plane almost caught up in flames. Gas was filled through the entire plane. Had a big scare."

Pros: "great"

Pros: "I liked the wide and spacious seating."
Cons: "Due to the planes running late we had to board the plane without the plane being cleaned beforehand. I had to ask a stewardess to wipe down the crumbs and spilt coffee on my seat before I could sit down. It was REALLY disgusting!!! There was crumbs all over the seats, Seatbelts and floor."

Cons: "N/a"

Pros: "Good entertainment selection"
Cons: "Most was as expected."

Cons: "On time"

Cons: "I didn’t like the fact I had to wait 5 and a half hours in the airport and not being compensated by the airline, who for some reason penalize anyone of their passagers if they are late or want to change a flight. I was also late for a meeting"

Cons: "Had a mechanical problem and took us 30 minutes to take off"

Pros: "The flight was on time. It was smooth and we had absolutely no problems"

Pros: "I like the in-flight attendants as they are courteous even though it was late night flight. I cannot complain at all."
Cons: "Gate agent refused to try to put my 9-year-old son to sit next to me. She said "It's full flight" right out of the bat. Well, even if that's the fact of the matter, at least, be kind in responding to customer's inquiry. My son was seated across the isle, same row, but in reality the row was not even straight. And as a little boy, he cannot sleep straight and he has to lean to a stranger's shoulder? Thankfully I got a nice gent who should have sat next to him who were so kind to exchange seat with me. It's all in the attitude.... hopefully my attitude is not as bad :-) But maybe the gate agent was so tired for it was the last flight from ONT, at 1 AM. Bless her heart! Thank you though for your help to get the plane leave on time.!"

Cons: "Cramped seating"

Pros: "Nothing"
Cons: "I bought travel insurance as I do with any trip. I have a complicated family emergency that forced me to call off the trip. Being that I bought trip insurance, I felt good. Well turns out they make you jump through so many hoops that your travel insurance fee is useless. I sent a letter to Allianz (the company that handles the travel insurance) and blasted them for their insensitivity in a difficult time. Going forward, I will not be purchasing travel insurance in the future. It may sound irrational but if you think about it, travel insurance is the tax on gullible people. You hear travel insurance and one assumes that if you spend the extra money on the insurance and something comes up, you can at least get much of your money back. Don't count on it! It's a 1/1000 chance they will do the right thing so the odds are not in people's favor. If you want to be smart, use the money you would have spent on travel insurance on some pre flight cocktails at the airport bar. Air travel is hellish enough without scams like Allianz!"

Cons: "Leg room/space BA offers is calculated for short and small body frame passengers and it is on not acceptable. It feels like cattle Wagon. BA should show consideration for real passengers not some sort of statistical average. I am 6'4" and sitting in your plane's cabin inflicts hours of body pain. The space given is sufficient for children and teenagers. Also sitting in the hot cabin for extended amount of time is extremely uncomfortable. Why there is no cooling and proper air ventilation right from the beginning?"

Cons: "Flight was cancelled"

Pros: "Full can of tomato juice, head rests on the seat, relatively roomy seats and happy attendants."

Cons: "The fact that we didn't know we were supposed to go to American Airlines to acquire our boarding pass. A heads up would've been appreciated."

Pros: "Love these Non-stop to Austin even though they are always full. Thanks for this luxury of non having to transfer in Dallas."
Cons: "The down side is that these planes are smaller so we didn't have any entertainment and therefore no place to charge digital devices. There is however, wifi to purchase."
