Cons: "Everything at the Atlanta Airport. From the airport and staff itself to those working for Delta Airlines. It has been so bad, that I am thinking of flying with American Airlines again and avoiding the Atlanta Airport all together. Absolutely the worst airport in the country, Delta not much better"
Pros: "Good entertainment options."
Cons: "Only water and coffee available. Flight had been delayed over an hour."
Cons: "I paid to be in row 1 first class, when I checked in I was in the first row, then as I boarded I was told my seat changed to the back row in first class for no reason at all. I choose the 1st row for a ready and I expect to sit there! 2 flights in a row that Delta moved my seat for no reason"
Pros: "Entertaining crew"
Cons: "On time arrival (we were late)."
Pros: "I like flying Delta. Make you feel comfortable and at ease."
Pros: "The crew was nice, the flight was so short, there was little interaction with them."
Cons: "Boarding was a disaster, people didn’t have seats which caused a delay in boarding. It was a mess. The seats were uncomfortable and too small. I know it’s a short flight but it was just too tight in there. The flight was delayed and the communication was all over; the time was constantly changin"
Pros: "Don't know yet, because I have not left Korea."
Cons: "Not happy that DELTA changed my flight again and now I arrive (6) hours later in Philly. Longer layover in Detroit is not comforting! Hoping/praying that DELTA doesn't change more on this flight going home!"
Pros: "nice crew"
Cons: "terrible seat comfort, late departure due to airline’s booking problems"
Pros: "We left early"
Pros: "All the movie choices. Wish TVs came in all aircraft and/or flights 2+ hours. :-)"

Pros: "Smooth , fast, comfortable"
Pros: "Crew was awesome"
Cons: "No TV unfortunately"
Pros: "What I liked was getting to my house."
Cons: "The air-conditioning was extremely cold; on the positive side, I was given a blanket. The plane did not have any kind of tv screen in which to watch films or programs. Space was unbelievably tight between seats and rows; I cannot imagine a horizontally or vertically big person having any level of comfort. In general, the service was quite poor, making me wonder how does Delta treat the flight attendants, for they seemed tired and careless. The above did not happen in any of my other flights: Atlanta-Guadalajara, Guadalajara-CDMX, CDMX-Atlanta."
Pros: "Everything, smooth flight with an entertaining crew."
Pros: "The exit row seats reclined."
Cons: "USB charging didn't appear to work. No meal service. Very brief lay over. This is bad because a 6A flight from RNO to SLC with a <50m layover and then a SLC to PHL flight means that you do not get any food until 11P when landing in PHL."
Pros: "Crew was great"
Cons: "No entertainment on flight. No smoking in Minneapolis airport"
Pros: "Everything went smoothly. The staff were friendly, the flight fast and calm."
Cons: "Nothing that can be done, just tough being 6'5" in a connection plane."
Pros: "Made it out of Detroit that same day! Friendly flight attendants!"
Cons: "Flight was delayed. And then cancelled. We were booked into a later flight 8 hours later that was also delayed again due to weather but we did make it out of Detroit that night. Other people were not as lucky."
Pros: "They have great and friend staff."
Cons: "Delta treats any passenger that isn't a member of their skymiles or anyone that doesn't purchase a seat in advance like peasants. You don't get assigned a seat until YouTube up at the airport... That's fine, not really a big deal. But because you didn't select a seat, they don't let you print or view your boarding pass on your phone, forcing you to go to the checking desk. For someone that has TSA pre check and travels alot, all that extra time adds up and can sometimes cause you to miss your flight. Because there is on "fast line" when you check-in like there is at the security check point. I only have this problem with Delta, never American airlines..."
Cons: "my flight from JFK to Cancun had entertainment (TV, movie screen, headphones, etc). This one did not. Was kinda disappointed."
Pros: "Seats were comfortable"
Cons: "If flight is full all the time get a bigger plane"
Cons: "NO ENTERTAINMENT no snacks on the second flight after an hr 24 layover AND 52 minutes delay, seat near the bathroom which smelled horrible"
Cons: "All "carry-ons" were taken at the jetway, which was fine. But, when we landed, as passengers were trying to get off of the plane, the attendants were putting all of the collected luggage at the entry to the jetway. It created congestion. Then, anyone who had luggage, had to lineup against the side of the jetway, awaiting their luggage, and increasing the congestion. First, it was inconvenient. Worse, if there was any kind of emergency, I believe it would have created a unsafe environment. Very Poor Design & Process ! ! !"
Pros: "Our plane had mechanical issue with a parking brake which they left us know about once we loaded the plane. Unfortunately it was going to take to long so they switched us to another plane."
Cons: "Airlines in general need to enforce the carry on luggage rules. If it doesn't match the dimensions for the carry on specks then make the people Check it. Don't let it go. If I paid for a seat and I'm allowed two carry ons then there should be room for them. Don't ask people to check bags because of a full plane. The crew should have there own place to store their belongings, not where the passengers do and take their space. The life rafts need to be easy to get to but again should take up a spot a passenger has paid for their luggage to go. If that is the only space for these items then don't allow passengers to bring two items if in those seats or on the whole plane. It's really disappointing when your told you may have to check your bag because there's not enough room."
Cons: "I sat in a window seat and they put a 350 lb person in the center seat. For 3 hours I was squished against the wall. Flight attendants noticed but did nothing to reseat either of us."
Pros: "seating at row 2a was roomy enough only because the seat in front was empty do no danger of a recline. The service was excellent, entertainment options excellent and products in bathroom are nice - Malin & goetz. The captain came out and greeted everyone, which I appreciated"
Cons: "The food served for dinner was not great. Pasta with a mushroom sauce. Sauce was really soupy. I'm not really crazy about the snack basket options - not enough savory and no chocolate. The seats on the new 737-900 are not comfortable"
Cons: "Old plane. No seat back entertainment. No USB ports"
Pros: "The attendants"
Cons: "The delay and no free wifi."
Pros: "On planes with seat back displays, it was especially easy to travel with a 4 year old. Definitely appreciate the entertainment provided."
Pros: "Tail winds provided an early arrival. When my flight was rebooked due to a delay on my first booking I was upgraded to Permium booking and drinks were complementary on the flight from Atlanta to Philadelphia."
Cons: "Super loud. Couldn't talk to anyone without shouting. No view out the window, as the engine was about 5 inches outside the glass. Not sure why there even were windows for these seats, as they probably just let in more sound. Also right next to the bathroom, so frequently smelled bad."
Pros: "I took two connecting flights on American Airlines between Los Angeles and Lisbon period on the website American claims to have charging and or electrical ports in every row. There were none on either flight. To make matters worse, when my tablet and phone batteries both died before the end of the first flight, there was no inflight entertainment, other than 1 ridiculous thing available, on either flight. American has switched to BYOD for entertainment, but forgot to provide a way to charge our own devices. Incredibly stupid."
Cons: "On top of that, one of the flight attendants on the Philadelphia to Lisbon run was a hella snarky guy with a bad attitude all the way through. I would be surprised if I am the first person to complain about him."
Cons: "The spacing between rows, the aisle and size of seats were terrible. I will go back flying British Airways and Lufthansa!!!!!"
Pros: "No complaints honestly. Crew was friendly, boarding was painless, and flight was comfortable."
Cons: "The plane was old, but it didn’t really impact my flight at all."
Cons: "Flight was delayed & ultimately cancelled. Replacement flight required going to another airport. That flight too was delayed putting at risk our ability to make the BA flight to Lisbon. Therefore, we took AA flight to JFK and a TAP flight to Lisbon.did not take this flight."
Pros: "Both flights were great. No issues at all with either of the flights or airports. Layover was just long enough to get through customs and get something to eat."
Pros: "30 year old plane!"
Cons: "No oilers, no individual monitors!"
Pros: "We were very well looked after by a group of male flight attendants. The plane was clean, calm, quiet and we had all we needed."
Cons: "I was rebooked and the process between American and British Airways was very confusing. I was lucky to get a seat on the plane which I had to pay extra for even though I booked in January for an August flight. Also it was crazy that there was no inflight entertainment for such a long flight."
Cons: "British Airways moved us to American Airlines. AA canceled the flight like two hours before the flight was scheduled to leave Baltimore to Philly. Never received any information from either British Airways or American Airlines.i was able to ctahc the second leg of the trip by driving to Philly Airport."
Pros: "The aircraft, the entertaining"
Cons: "Food service"
Pros: "Crew was nice."
Cons: "Plane was very old (from the 90s?), cabin kept freezing all night. Now my husband's luggage has been lost and we are getting conflicting information on how to retrieve it."

Pros: "We were20 min early"
Cons: "The seats are stiff"
Pros: "Flight was on time."
Cons: "One bathroom was out of order, staff appeared very tired, food service was missed twice on one side of our class section like they didn't have assigned sections. Also, the food and drink options do not compare to British Airways who we originally purchased our tickets from. All alcohol is free with BA."
Pros: "I liked the boarding in groups. The crew was nice."
Cons: "The inside of the aircraft was so outdated. The seats were not comfortable with very little leg space. There was no individual screen for entertainment, and no USB port."
Pros: "Decent legroom, good movies"
Cons: "Food was terrible quality and actually made my mom vomit. Crew was pushy and rude."
Cons: "Many things Food Services Entertainment"
Pros: "Nothing special just another flight another day"
Cons: "AA...they delayed flights and were very unprofessional. i will definitely choose BA over AA anyday."
Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."
Pros: "Nothing — the flight was cancelled because of a fault on the plane."
Cons: "Cancelled flight.."
Pros: "The plane was nice and clean. Boarding went well and staff nice on boarding. Service was smooth though food not great but then it is airplane food. The morning continental food was nicely packaged and good."
Cons: "The plane boarded and left gate a little late but had a maintenance issue with one of its doors so plane had to return to gate. We finally got off the ground almost three hours late but staff tried to be as helpful as possible though they didn’t know much. It was good the passengers seemed fairly patient and accepting. The horror was at the airport in Venice where it took over two hours in very long line just to get through passport check."
Pros: "Crew was hospitable. :) movies were great."
Cons: "Snacks were lackluster."
Pros: "The stewardess were very nice and poliet"
Cons: "the seats not having enough room to get comfortable"
Pros: "Reasonably comfortable seat. Nice crew"
Cons: "I had a screen with excellent selections but the audio didn’t work. They reset it twice but nothing. Started watching a movie with CC but 40 min in it ‘died’."
Pros: "The very long TSA line was very fast. Good job TSA. Flight attendants were very attentive."
Cons: "Found the first class seat capsule uncomfortable after about three n hours. Certainly would not want it for Transocean flights."
Pros: "They offered us a little scoop of ice cream."
Cons: "My video screen was busted. Long 9 hrs without anything to watch. Food was cold (as in not reheated after being frozen). Landed at PHL and sat at the gate for 45 min before deplaning, which made us miss our connection. Apparently there’s NO other gate to deplane from than the one they picked. Ridiculous."
Cons: "I had to put my carry on item 10 seats behind my seat location. That delayed my leaving of the plane to my next flight."
Cons: "Sitting next to emergency exit door with a peep hole for light. Also next to toilette so everyone had to pass us. No overhead above us so our medical and personal items were stowed in 3 places initially."
Cons: "Very long time since I have being on s flight with tv in the aisle , and not on headrest .. this is s international flight ."
Pros: "Despite numerous delays, we made it to Philadelphia. We were alerted to the delays in a timely manner. We were also treated to a snack cart and cupcakes to celebrate the first day of direct flights."
Cons: "A long delay. Patience is everything and the staff and crew were very friendly."
Pros: "Not much here. The seats were ok, but the rest of the flight the airline was just poor."
Cons: "The airline is so outdated and behind the times of their competitors, their in that they don't have in flight entertainment unless you download their app and give them your email address. On top of that when I originally booked my flights, I had made sure to have 1.5 hr for a layover between my connecting flights. Well, they decided to move up my connector such that I had 25 minutes to run across 2 terminals. They only give you pretzels on the plane, and a single soda drink. They offer you "food bundles" but why do I want to pay $8 for a sandwich that costs $1 to make."
Pros: "Boarding eas good and crew was very good."
Cons: "The three hour delay and the terrible food served."
Pros: "It was American Airlines flight. Some of the crew members were not very polite but majority complied with providing a good service. The plane and the flight were great. The entertainment was good too."
Cons: "Bad manners from some of the crew members like snapping fingers to get your attention. Very impolite."
Pros: "It was worth while upgrading to premium plus for the first time I was actually comfortable flying the crew is always kind and caring and the food was. Better than usual. Unfortunately Heathrow employees board handicapped people and the are horrible. They didn't come to board us until the plane was 75 percent boarded which is just unacceptable for a wheelchair user who cannot stand. BA had to stop boarding to get us aboard the plane with the help of BA crew who are great."
Pros: "Price and service"
Cons: "Outdated airplanes"
Cons: "We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall."
Cons: "Baggage was lost!!!!!"
Pros: "It was fine"
Cons: "It was a full flight, but I cannot complain"
Pros: "The entertainment was free on our flight and that was very nice. Watch a lot of movies iv been wanting to watch. Pilots flew the plane very well."
Pros: "Flight on time."
Cons: "Paying extra money to pick seats before 24 hours check in. I have 2 children and cannot risk them sitting separated from their parents. I'm sure other travelers would not want a 6 year old aline next to them either."
Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"
Pros: "Quick boarding and on time departure"
Cons: "Late by 40 min"
Pros: "great service from flight attendance"
Pros: "On-time departure, and on-time arrival. Just the way I like it."
Pros: "Transport to international terminal was a breeze"
Cons: "Very few food vendors open in the international flight area"
Pros: "The crew were all excellent, the people trying to reroute us were all kind (though one accidentally booked me incorrectly), and once the plane got there the flight was very fast."
Cons: "The airline was really late replacing the plane with the mechanical failure. The gates at Philly were much too far apart to actually make that connection - shout out to the Philly staff who sent is an electric car! But it was a panicky experience."
Pros: "We got free upgrades to 1st class as we used to get at USAir! Great surprise."
Pros: "Crew was proficient."
Cons: "Seating was compact, reminded me of the buses that run from Mexico to the US. "Let's see how many we can fit in there?" Rubbing elbows the entire time."
Pros: "That I survived."
Cons: "30 min delay because of a.c. and still was not fixed"
Pros: "The man at the counter gave me a much better seat than I originally had. He was pleasant and very customer-friendly. I can't remember his name but he had brown hair, glasses and a mustache. I was extremely exhausted from my Las Vegas flight and it helped me greatly."
Cons: "Slow, rude check-in staff almost made us miss our flight. Crew was unpleasant to us. One member was wearing a repulsive, visibly dirty uniform shirt. No service due to turbulent flight."
Pros: "Boarding on time, wi-Fi entertainment and staff were friendly"
Cons: "Nothing to suggest"
Pros: "No think special!"
Cons: "Small space and no entertainment on an international flight."
Pros: "I did like that we boarded quickly and efficiently. The attendants were very respectful and kept very quiet throughout their food and beverage service so others could sleep which was quite professional."
Cons: "I didn't like that the only guy on the flight that kept his light on the entire trip had to sit next to me. I was able to sleep regardless, and I understand that it is out of the control of the crew or myself or anyone but that guy... but that was less than desirable. Other than that, great flight."
Cons: "What food? A little snack mix. And once again, needed to get in and out with a shoe horn."
Pros: "Everything went smoothly and as planned"
Pros: "Attendants were nice."
Cons: "No entertainment screens & last seat didn't recline."
Pros: "In flight entertainment worked. Staff was friendly."
Cons: "I had no issue with the delay, things happen. I was dealing with a knee injury and the gate plan had us all over the airport. It was quite frustrating to get to a gate in another terminal only to get told we were being moved back to the terminal we had just come from! Then that gate was changed again, involving another long walk on said bad knee!"
Pros: "Comfortable the entire trip! 1st class is the only way I will travel any more especially flying all the way across the country! Thank you United!"
Pros: "The crew members were very friendly"
Cons: "My seat was a tad bit uncomfortable."
Cons: "The flight attendant was very rude and made my experience very stressful."
Cons: "There was a sick passenger on board. The crew spent 40 minutes trying to convince him to get off the plane. He refused and after 40 minutes, they left him on and we finally left the gate."
Pros: "We were lucky there was an empty seat on our row of three, which made it a little more comfortable."
Cons: "Some of the crew was not helpful, cramped, no food. Next time will book 1st class for a 3 hr flight. We were delayed 1 1/2 hrs due to weather in Philly, nobody's fault just inconvenient."
Cons: "United was boarding at least TWO flights out of the same gate, at the SAME time. My luggage was delayed and the United agents in philly told me it would be in at 7 pm... It was in at 7 pm two days later. They sent it to Knoxville for some reason? Will not fly United again."
Cons: "There's no spave at all between your seat and the one in Front of you. I couldn't leave my seat to go to the restrooms without shamefully jumping into the two gentlemen's sitting next to me"
Cons: "No hot food"
Pros: "Professional airline. Comfortable seating. On time. Most impressive airline I've flown with in a very long time."
Cons: "The Flight was late taking off with no explanation. We were on the plane for an hour prior to takeoff with no AC. The cabin was extremely uncomfortable."
Pros: "Flight proceeded as scheduled."
Pros: "flight attendants were pleasant. plane was clean"
Cons: "I was stuck with commercials for direct tv, two feet from my face the whole trip. I would push the button to turn tv off but it would come back on less than five minutes latter. I had my head phones in listening to personal device but was still distracting. speaker for announcements were extremely loud. the poor lady next to me would jump and then plug her ears. question, if you are allowed one carry on and one personal bag, why do you only have space for a third of the passengers to stow said bags?"
Pros: "honestly nothing"
Cons: "Both my flights were delayed. The seats are cramped and uncomfortable. They don't give any food at all. There is no free entertainment."
Cons: "Had to pay for my own shuttle to the train station (an hour away) and sit on an overcrowded train for hours. Extremely disappointed. Flight was canceled do to "air traffic control." No attempt was made to put me on other carrier's flights even though there were open seats with another airline."
Pros: "Boarding was nice, and fast, but inly because I'm handicapped. Crew was pleasant."
Cons: "I didn't like having to pay $4/2hrs for internet/movies for a 3 hour flight....$8 to watch a movie on a 8" screen?? Come on! If you have it available, why isn't it free or included in $600 ticket price? I'm 6'0" tall and weigh 218lbs and I felt like a sardine in a can. Seats are WAY cramped! They probably are comfortable for a 7 year old girl...."
Cons: "flew delta on way down to liberia and they did not charge for any entertainment."
Pros: "We were slightly delayed departing because of a mechanical concern. Thankfully there was nothing wrong so we departed within a few minutes. To compensate the pilot authorized free direct TV for the flight. Very nice I enjoyed a movie. We landed on time."
Cons: "Direct TV cut out for a couple minutes."
Pros: "Flight left OT."
Cons: "Uncomfortable slimline seats."
Pros: "Everything was ahead of schedule."
Cons: "Had to pay for Internet to watch airline movies on my device. Not enough leg room."
Cons: "Never got there due to my first flight being cancelled. BUT, I did see from my emails that this flight was delayed multiple times and then cancelled as well."
Pros: "The lcd screens in the back of the seats and the availability of watching whatever you wanted was nice. The flight was short so TV cost $5.99. Usually wouldn't do it but the Masters was on so it was a great way to pass the time!"
Cons: "The delay due to weather."
Pros: "On time"
Cons: "paying for baggage no food service"
Pros: "Great comfort. Great crew service"
Pros: "Courtesy of staff"
Cons: "After the flight was delayed a hour and a half, they said we would have complimentary TV access, but it there was no tv sign for more than half of the flight."
Cons: "The plane was supposed to have WIFI but it didn't."
Pros: "Our flight was two hours late. We received no water on our flight. We had to wait in the cold/outside to get our carry on bags. Flight attendant was not in the mood, and looked like she was taking it out on the passengers."
Cons: "Confirmation number N89G3L. Literally just look at what I had to go through to get from Denver to Liberia and back. In total; 3 cancellations, 9 delays and had to leave the plane after being boarded 3 times in a row at Houston. Unacceptable. I would like to get money back for this trip, as it took off two days of traveling and took us well over 48 hours of travel time within airports. Is there any way I can be put in contact with someone from United Airlines about this? Thank you."
Pros: "Courteous crew. On time flight( in fact, we arrived in Philadelphia early) love that. Clean plane. Looked new."
Cons: "No drink, no entertainment."
Pros: "The crew."
Cons: "We were delayed at the gate then delayed again on the plane brocade they couldn't find someone to fill the fuel tank. Once that was complete, we had to wait quite some time before the slip came to the plane to be signed off on. The last issue was that they couldn't get the aircraft pushed out of the gate. The only positive was that my bags arrived this time."
Pros: "Left in time; arrived in time"
Cons: "Can't sleep on a plane; it isn't the fault of airline"
Cons: "The flight was delayed 2hours from the original departure time."
Pros: "Non-existent! !! Canceled AFTER the first leg if the flight....leaving us stranded."
Pros: "Plane happened to be empty which made flight comfortable in terms of space. Ticket price was very reasonable and included departure tax (274 roundtrip LIR to EWR)."
Cons: "Had to pay 8 dollars for TV and if you want Internet it's another charge. Five hour flight with only food offered being purchasable. Boarding process has become idiotic as later rows board last causing delays (should revert to old way where back boarded first which prevented aisle from being blocked as much)."
Pros: "The flight was fast a head of time."
Cons: "By the time the flight attendant got to our row, she was out of orange juice. Can't believe they don't give out peanuts or pretzels any more. They do on southwest. Once again the steps boarding plane. Very difficult for me to handle. The walk from one end of the airport to the other."
Pros: "Nice crew. Easy boarding/unboarding. Appreciated having my carry-on (not having it gate-checked). Comfortable for coach."
Cons: "On board entertainment did not work."
