Airline reviews

Pros: "Social distance and crew was very nice."

Pros: "The crew was good, and the airline tried to make our wait in the airport as comfortable as possible."
Cons: "The four-hour delay was really hard. Since it was in DC, I don't know why it took so long to get another plane."

Pros: "Quick boarding process and take off. Flight was slightly late but the staff expedited boarding and take off. Staff is friendly. Service was great. Beverage service was great. Baggage was quickly at baggage claim."
Cons: "Even though its a short flight better food options for First Class would be appreciated."

Cons: "Old plane with no video screens or room. Boo!"

Pros: "of everything."
Cons: "travel time ...ahahah ...."

Pros: "Crew ok ... not engaging"

Pros: "As always the Delta crew was super friendly and helpful and made the trip very enjoyable."
Cons: "Everything was perfect"

Pros: "Nice on board crew."
Cons: "More arm & leg room in basic seating. Tray tables are flimsy and seem worn."

Pros: "Predictably late."
Cons: "Be on time."

Cons: "The flight was delayed over two hours"

Pros: "Information communicated about delays."
Cons: "- more communication (any!) about bag status when landed - flight delay due to too many/too heavy baggage. Long delay was said to be due to making sure our baggage would accompany destination. Upon arrival, bag was left in NYC but this wasn't communicated. No info on bag status at airport or via ema"

Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"

Cons: "Wider seats, more leg room"

Pros: "Very good"
Cons: "Seat assignments should have be provided at check in."

Pros: "The crew was dealing with NOVA/DC residents"

Pros: "Coming from Europe Alitalia and Delta did an EXCELLENT job at assisting the passengers get rid of their luggage just as soon as we were done going through customs... I don't usually fly on this route, but I thought it was perfect. Transfer between Delta terminal was a breeze too..."
Cons: "I usually don't fly from JFK. The food court was expensive (18 dollars base price from a burger seems a high even for an airport. I don't fly from NY normally - so maybe I need to tune my expectation for the locale, and it may have NOTHING to do with the airline company."

Pros: "Efficient, cheerful crew"
Cons: "Stop making seats smaller! The added revenue from 10 squeezed seats is not worth the discomfort it causes."

Cons: "There was a mechanical delay and I ended up missing my flight. Even though I arrived 10 minutes prior to departure."

Pros: "The crew did their best to accommodate for the hot mess."
Cons: "The temperature was unbearable. My dirt and pants were soaked with sweat. It was very hot."

Pros: "The service is very good from the beginning. The flight attendant is very caring thanks so much."

Cons: "The aircraft is too old, MD-88. I don't know how Delta is flying that type of aircraft. Is very risky"

Pros: "Another safe flight. Crew was very attentive."

Cons: "The schedule was not good and I was needed to take later flight than I ordered."

Cons: "Flight cancelled due to weather that was never bad but on the potential of bad weather. Had to scramble so my 18 year old son was not stranded overnight in a strange place and Delta does not help. Only rebooked a flight itinerary for the next day for a 4 hour flight with connections on a 1 hour direct flight. Spent an hour on line to figure out what to do. #neverdelta"

Pros: "See above."
Cons: "Nothing. Really."

Pros: "Nothing"
Cons: "Plane delayed 4 times for a total of 4 hours"

Pros: "The flight for getting us therw"
Cons: "No food and no entertainment"

Pros: "It was too cold on the flight. I asked for a blanket and luckily the stewardess had one. However, before giving it to me, she told me it was the only one on the flight!"

Pros: "Friendly, leg room, on time."

Pros: "The attendant was most helpful. Because the flight was not full, she allowed us to sit in the exit row, window and aisle, with no one between. I'm a tall person, so the extra leg room was deeply appreciated. I give her and the airline high marks."

Pros: "The flight was good, Boarding was smooth and fast"
Cons: "I asked one of the crew members to help me to get a better seat as I was very tired and wanted to sleep better during the flight and he didnt pay attention to me. I realized there were emthy seats available during the flight"

Pros: "Love the entertainment options."
Cons: "Very limited snack options and seats are very narrow."

Pros: "Service"

Pros: "Entertainment options"
Cons: "Late pickup, then no gate at stopover causing is to miss our flight as we sat on the tarmac. Got on next flight, 5 hours later, the literal last row of the plane right in front of the bathroom, you know, those seats that don't recline? Travelling with a cranky two year old, made pains to select seats for maximum child comfort and it all flew out the window. Arrived at destination and sat, again, waiting for a gate. Signed up for sky miles previously based on good experiences, but this was one lane thing after another. Advice? Don't act like you're doing me a favor when asking people to check bags cause then it's "free"."

Pros: "The crew was friendly, relaxed, made everything seem like a breeze"

Pros: "Fast and very friendly staff."

Pros: "I could be wrong, but the seats were very comfortable (for a plane) and I felt my knees weren't as close to the seat in front of me than other airlines. So that's a plus."

Pros: "Good selection of free, in-flight entertainment."
Cons: "Our flight was delayed on the runway, but that wasn't the airlines fault."

Cons: "Delayed for an hour and fifteen minutes"

Pros: "Comfortable flight, ample leg room, and the chairs were pretty plush. Comfort+ is pretty nice"
Cons: "On my first flight they forgot to turn the wifi on. I have unlim data but obviously can't use while in air; no big though."

Pros: "flight attendants were great."
Cons: "not enough leg room and space. The business class should be at the minimum for economy."

Pros: "everything on schedule; courteous staff and great pilots"
Cons: "everything was very ordinary so cannot complain"

Pros: "The only flight that was a bit better was from Mumbai to Hyderabad."
Cons: "Almost the entire trip, due to the following reasons: 1. The online check in process didn't work at all. The Delta staff at the Boston airport weren't pleasant and courteous at all. 2. Poor coordination between Delta & Jet Airways - the meal preference was selected before flight at the Jet Airways website but the same didn't get registered properly, even though the website confirmed to me that it was all set. This resulted in appropriate food not being available to the customer on the flight from Boston to Amsterdam. The customer had to literally starve on the flight. 3. The pursers and stewards on the flight from Boston to Amsterdam weren't pleasant and courteous at all. For anything they were asked, their responses ."

Pros: "The crew was polite and friendly"
Cons: "My second plane had sooo much moisture coming from the cooling system it looked like the passengers were getting gased and I kept getting wet from water condensation falling on me in a window seat as I tried to sleep from having such an early flight to begin with only to be told it's delayed 3 hrs without explanation."

Pros: "Good seats."

Pros: "Free drinks in Comfort+"

Pros: "Perfect"

Cons: "See above description"

Pros: "Individual screen and USB port"
Cons: "No issues that could be controlled I.e. Person in seat in front for mine leaning way ......"

Cons: "Nothing"

Pros: "Flight was not over crowded, allowing for proper social distancing! That is MUCH appreciated. Crew was wonderful."
Cons: "The couple in front of me got in a physical altercation as well as the couple seated behind me. Both situations caused much discomfort and could have been defused faster by flight crew"

Cons: "Not delayed"

Pros: "The captain was very professional"
Cons: "Departure was late because of problem with thrust reversers. Once the plane started to push back after 1,5 hours delay, we had to return to the gate for another 30 mins because of an error on the maintenance logbook entry."

Pros: "Great crew"

Pros: "Arrived alive, didn’t sleep in the Charlotte airport like last flight. didn’t lose a bag....didn’t check one, learned that lesson before"
Cons: "WiFi did’t work. Boarding the end of the terminal/gate was a mess. Crew was late, so flight was late. Packed in like sardines....normal American Airlines."

Pros: "The crew was very nice and helped me with what I needed."

Pros: "Everything"
Cons: "Nothing"

Cons: "Paid for First Class so I could sleep on this red-eye. Wasted my money. Seat was uncomfortable, legroom in my bulkhead seat was horrible. I can sleep anywhere...make that ALMOST anywhere, now."

Cons: "There was a three hour delay for missing crew."

Pros: "Food and staff are great"
Cons: "Small space between seats"

Cons: "Not comfortable seating bad food fruits were smiling and they made me to check in my carry on bag to charge $60 Will not recommend or travel international again with this airline"

Cons: "Caught an earlier flight and the entire team made the process seamless."

Pros: "It’s not like it used to be. U S based airlines lag behind their European and Asian counterparts"
Cons: "There’s always room for improvement. Too much to list here"

Pros: "many movies"

Pros: "On-time departure and arrival, friendly ground staff and flight attendant"

Pros: "Entertainment"
Cons: "Boarding and the crew was not nice"

Pros: "None"
Cons: "The flight delayed several times, and the gate was changed. The plane is very old and no service at all (not even water during the 2 hours flight)!"

Cons: "in the airport, the gate area dirty!, bathrooms dirty, no place to charge phone. The walk to the airplane, getting aboard the plane after the gate and flight changed and delayed. Being told it was weather related on the plane and being told it was MAINTENANCE by customer service. The plane was very crowded, the flight attendants never smiled. WHen i told the attendant i was being "rained" on he said...i know its happening everywhere..... he said there was nothing he could do but get me paper towels...they never came. I was very annoyed getting off the plane walking back and forth....it was aweful. and my flight before this was no better i am VERY TURNED OFF BY AMERICAN AIRLINES RIGHT NOW."

Pros: "I had a connection flight to JFK I came before the time about 15 min and crew saw me but she told me, sorry someone took your seats I lost around 4000$. This happened at Dallas airport."

Pros: "The crew were polite, accommodating and understanding"
Cons: "The gate was changed 1hr prior to boarding despite the arriving plane having landed 3hrs prior. So with stroller and infant in toe, I had to run to change terminals/buildings. There was no assistance or prior warning regarding this from the check in staff and I made it all the way to the original terminal and gate before having to turn around. The desk staff at the gate was asked about early boarding for infants and said it would be okay but didn’t give clear instructions on boarding so I sat down and they began boarding each group 20 minutes later and did not give priority to mother’s with infants. The stroller which I brought to the gate was then tagged incorrectly with a white tag instead of a pink tag. I was later told by he crew that it meant it would go directly to baggage claim instead of being brought to the door. According to the crew, all staff know to tag with a pink tag. At every step there was blatant display of inconsideration that made an already difficulty journey, that much more challenging."

Pros: "The airline staff was SO kind and helpful. I'm an AA fan now!"

Pros: "Left and arrived more or less on time. No major issues."
Cons: "Gates are way too far apart in Miami and the golf carts to get between areas seem to require reservations and long waits. Ridiculous. Most MIA staff was very rude (this wasn't American's own staff, or TSA, I should note). American stripped my group of our seat assignments (which we had selected 6 months prior) without reason and with minimal apology. No solution offered. Got middle seats but luckily was able to switch on one of the computer kiosks. Flight crew didn't seem to care that other people moved to the for-pay seats further up front (the flight wasn't full)... so why did we lose our seat assignments and get grief with not being able to select anything good? Not impressed."

Pros: "Quick, efficient"

Pros: "The fact we arrived safely"
Cons: "Long time to claim baggage, three hours delay, uncomfortable seats"

Cons: "I need to be able to charge my phone on the airplane!"

Pros: "Crew and other personnel"
Cons: "I was not able to select a seat 24 hours before flight"

Pros: "I liked arriving safely, although we were an hour and a half late"
Cons: "American switched pilots last minute, so all passengers sat waiting in our cramped seats for about 15 minutes while pilots got situated in the cockpit. Then it was discovered a preflight mechanical check hadn't been done. So we all sat for another HOUR waiting for the mechanics to arrive and do their work. The flight attendants were unpleasant and rude."

Pros: "I appreciated the interactive screen on the backseat, which provided me entertainment watching Doctor Who and playing Angry Birds. I also liked that the power outlet to charge my phone was more accessible on the backseat instead of below my seat, which is normally where I find it."
Cons: "I did not appreciate that there was a device mounted below 2 of the 3 backseats in my row. Those devices cut into at least a few inches of valuable room to store a carry-on bag. At worst, I've seen 1 seat have such a device, so it was quite disappointing to see 2 seats with them, including mine."

Pros: "Nothing"
Cons: "Although I should now be at my final destination, I still have 11 hrs of travel to go. My flights were changed three times. The first cancelation caused me to buy new tickets at a higher price I had originally purchased them at. We were redirected from Kayak to Vayamo and they have no sense of customer service. Horrible"

Pros: "Nothing"
Cons: "They had a delay that bumped our international connection. We had to switch airports and airlines and arrived significantly later than originally planned, causing us to miss pre-wedding events."

Pros: "not much"
Cons: "not much"

Cons: "Rude crew, no bathroom useage for entire flight and staff would not help handicap with luggage."

Pros: "The people where great. But this does not make up for what happened."
Cons: "1. Undisclosed LAX bus ride time limit to get to gate. BS 2. Undisclosed LAX bus ride to gate. BS 3. Alaska Airlines never explained at ticket purchase that it was at American Airline Terminal. Caused a 8 min walk to AA terminal from Alaska terminal. BS 4. None of this was explained at ticket purchase. Not happy. Probably will never try to fly Alaska Airlines again."

Pros: "Cabin baggage allowance."
Cons: "No food, only purchasable snacks payable only with a card not cash. That incurs charges for those that are not US card holders! And extortionate prices. Wifi based entertainment so you need your own tablet/phone. Great if the wifi works - it didn't. Neither on the outward or return journeys."

Cons: "They cancelled my flight in the middle of the night and rebooked for 3 hours later really strapping me for time at my destination"

Pros: "Love the direct flights from RDU to West Coast. Wish there were more cities on the list. The flight was delayed about 45 minutes after we boarded for take off. I hate sitting on planes idling. The seats are already uncomfortable, then add more time onto that to sit. But we made up the time in the air for an on time arrival. Hmmmm?"
Cons: "For a 5 hour flight at dinner time and then the 3 hour time change, the snacks provided are not enough. You just have to remember to bring food on the plane and then risk annoying your fellow passengers with the food/dinner dining space. More checks of drinks would be nice too. Cost cutting measures, but minimal considering a packed flight and pretty high ticket price."

Pros: "I loved our flight from Anchorage alaska to Los Angeles California. Flight attendants were kind and helpful. We had plenty of leg room and it was great flight. Loved our window seat."
Cons: "I didn't like that the flight attendants snarky attitudes when we would ask for son."

Pros: "The spaciousness of the seating on AA is tops bar none"
Cons: "The cookies and it was cold. Jesse"

Pros: "I think they were holding the plane for a connection flight arrival."

Pros: "Boarding was simple"
Cons: "For my whole three hour flight a child kicked my chair, i asked the mother politely if she could get her to stop. the woman didn't even apologize and the kicking continued for three hours."

Pros: "Being able to see movies for free was a real plus since the flight from Australia to Wash.DC is so long."
Cons: "Everything OK."

Pros: "Had row all to myself--that's a rarity"
Cons: "1hr departure delay"

Pros: "The flight was >1 hour late, which the pilot told us was due to the LAX controllers changing the landing patterns due to weather. So this really wasn't anyone's fault. But there was a large difference in comfort between this flight and the JAL flight from Tokyo. Seats were smaller, and my wife and I couldn't get seats together."

Pros: "The flight attendants were the most rude and upsetting people o have ever felt with"

Pros: "Older aircraft, seat cushion was on its last legs regarding comfort as I sunk to the frame of the seat. No onboard entertainment on the headrest as compared with our outgoing flight."
Cons: "The seat discomfort and the lack of entertainment."

Cons: "Significantly late & rude, as usual."

Pros: "Clean, friendly staff, great baggage tracking. Smooth flight."
Cons: "Overcrowded, but that's the same no matter where. Usual rude frequent fliers, who also usually take up all the overhead space."

Pros: "Getting off of that plane."
Cons: "I understand delays happen and are sometimes out of your control. However, customer service is something that you can, should, and must control. I witnessed a lack of self control of the American employees (including a Supervisor) and every point of my trip w/your customers. I was embarrassed for the American executive team."

Pros: "Much more legroom on this flight, even though it was a smaller aircraft."
Cons: "Gate agent seemed a bit overwhelmed. Helpful, but not overly friendly. In stark contrast to my earlier flight from Charlotte to Memphis, where the gentleman was extremely pleasant and cheerful."
