Airline reviews

"As with the outbound flight, this return flight was not full - maybe 40-50%. As they started boarding they announced they located a few people the help with 'load a balance' of the aircraft. What they had done was to compress all passengers in the middle of the plane leaving no space between anyone. It is difficult to understand why everyone is required to wear Masks, then relocated to remove all space between passengers, when there was ample room to allow everyone to be seated with space between."

Pros: "On time, clean and comfortable"

Pros: "Crew was fantastic. Seats are narrow in space, but more comfortable than other airlines."
Cons: "Drink and snack service, but captain was concerned about "bumps""

Pros: "The seats are not fabulous the crew was"
Cons: "They did a good job keeping us informed When we got really delayed"

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."

Pros: "Flight was on time out of JFK, and quick and easy to board. We took off on time and landed 30 minutes early. This is was a great trip, and I love Delta."

Pros: "It was an intern final destination and the boarding crew answered all my questions and put me at ease."
Cons: "Everything was perfect."

Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."

Cons: "Not cancelling our flight"

Pros: "Good crew, kind and hard working staff. It is so nice to have inflight messaging and that was a pleasant surprise that made the flight go quickly."
Cons: "I found the delta app to be less user friendly than the United one. I wish the in flight entertainment were in the Delta app versus downloading yet another app."

Pros: "No comments"

Pros: "The only thing I liked about the experience and flight was the Delta Sky Club"
Cons: "Everything"

Cons: "After my flight was delayed for over 3 hrs - the counter clerk was rude and unhelpful. She felt it was appropriate for her to flick the customer service phone number in front of my teenage daughters. I would say avoid Delta!"

Cons: "Couldn't have been better"

Pros: "Comfort + was nice."
Cons: "Had a middle seat between two other men. I was given my seat by the gate. It would have been nice if they placed my more strategically. That might be asking too much but seems reasonable."

Food was terrible! Choices were pasta and cold chicken salad. I had the pasta, which was bland ravioli in two bland sauces. I was surprised, because I had experienced better food on recent international flights."

Pros: "Newer plane with entertainment"
Cons: "was a great flight"

Pros: "Able to download boarding pass into apple wallet"
Cons: "Flight was almost an hour late departing, bag is a carry on but storage too small to keep bag, then wifi didn't work the entire flight. Had to run to our connection since our layover time was taken up in Boise. If we had missed the flight, we would have been re-routed to another airport over 1 1/2 hrs away since ours closes. Next flight was not much better, oh and wifi did I t work on it also - last 3-4 delta flights I've taken have been late and didn't have working wifi - starting to think their system doesn't work at all - seriously going to take any other carrier but Delta going forward"

Cons: "Couldn't adjust seat"

Pros: "On time, quick flight, nice people."
Cons: "It was freezing cold."

Pros: "The gate agents in New Bern were amazing at helping me find a seat that was next to an empty seat. I checked with the gate agent early and asked if she could accommodate my request (I'm a big girl, and any extra space on a plane is greatly appreciated!). Overall, I was very happy that they were very willing to help make my flight as enjoyable as possible."
Cons: "Nothing. Everything was great."

Pros: "On time departure and arrival, clean plane. Enough space for your carry on."

Cons: "Food was lacking"

Cons: "Security at Manchester was very slow - long enough make me ill from standing in one place too long. But then I was well looked after. The meals on both flights were identical; I don't think it can be a big problem to correct that. I took a long time to get accepted by the WiFi in the two lounges."

Cons: "Check-in Seattle was ill organized and folks cut and groused"

Pros: "everything from the boarding and check-in process to in flight comfort."

Pros: "The crew was great. The sandwich was tasty. And, I loved the leg room!"

Cons: "Not there. Still in germany"

Pros: "Good food and entertainment options. Efficient boarding and security checks. Some very pleasant and helpful crew members but some not (see negative comments)"
Cons: "Seating for tall passengers very cramped. Crew didn't make slightest attempt to help. Other airlines have noticed and helped regarding this. *Some* crew members were abrupt and perfunctory when they could have been pleasant. Nothing special was being demanded of them. Automated check in luggage machines are frustrating to use for many. many passengers."

Pros: "Nothing"
Cons: "Istanbul-frankfurt airline 2 hours delayed,that way miss a flight Frankfurt-toronto we said Lufthansa officer,officer said other flight tomorrow morning, final,no hotel,no flight,my wife and two kids sleep on the chair,perfect right"

Cons: "Gepäck bei Ankunft total durchnässt. Nicht tragbar. Musste Schlafanzug leihen. Papiere,Buch ebenfalls. Was jetzt? Sitzreservierung erst 23 Stunden vorher? Warum??? In Orlando Eincheckschalter schwer zu finden und von Delta Koffern davor blockiert. Ansonsten professioneller Service."

Cons: "Will newer agan fly business with Lufthansa!! It's not business at all just regular econom seats with short leg room and casual service. They should be sorry for that kind of business!!"

Pros: "I enjoyed my experience but the food was not that great ."
Cons: "Food"

Pros: "Nothing in particular"
Cons: "The shabbiness of the plane. The cramped space. The lack of overhead bin space. In fact, the space above my seat was full of suitcases of the crew. I had to find space somewhere else. If I had not been able to board early, I probably would not have found space."

Pros: "Handling crew was great . Seat was comfortable!!! Meal was very good and tasty"

And it took them over an hour to reroute my flight!"

Pros: "30 year old plane! Needs to retire this aircraft and move into the 21st century!"
Cons: "No outlets no individual monitors"

Pros: "That it actually happen. Poor communications from British Airways and American Airlines."

Cons: "I could not pre-check or request different seats on the CP website. I think that this was because of issues with the website, apparently due to IT system communication between American Airlines and Cathay Pacific.......on all six flights. On the transfer in San Francisco, Customs was closed when we arrived in San Francisco and we had to haul all of our baggage from one terminal to the other. There was no direction on how to handle this issue of Customs being closed while on the flight to San Francisco. I had to explain the issue of to the CP customer service crew in SF. The CP desk and they had never heard of it. American Airlines was equally poorly trained. I will also say that while at the CP customer service, there were three young adult males that we're not busy at the time and the watched us unload the baggage carts onto the scales and conveyor and then reloaded on to the carts to push to the AA terminal. We handled the bags two additional times because the CP staff did not know what to do and how to handle it. Other passengers were confused as well."

Pros: "Crew was friendly. Good food options in coach."
Cons: "Boarding process (AA in general) needs improvement considering the plethora of groups. Takes too long to board. New seats are downright tiny."

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: "We arrived safely and so did our luggage."
Cons: "PHL-Lisbon plane left 3 hours late due to CATERING problem. Seats were uncomfortable and food was awful. Lights and entertainment controls at my seat didn’t work."

Pros: "Great flight overall"
Cons: "Dinner could have been more occidental"

Pros: "Smooth flight, got in early."
Cons: "Breakfast was average. Could do better"

Cons: "We were unfortunately stuck on the tarmac for 45 minutes. I ran to my connecting gate but they had already closed it. There wasn’t a service rep at the gate. I walked to another gate and there was a very helpful rep who rebooked me to a nearby city. It overall was disappointing and caused me to get home about 3 1/2 hours later."

Pros: "On-time departure from PHL; on-time arrival in RIC, my checked bag was on the flight."
Cons: "Nothing."

Pros: "Plane was newer, had TV/interactive entertainment centers in the back of all the headrests. Crew on board was polite, cheerful, & friendly. Excellent service from the on board staff. Plane had WiFi & plug ins to charge/use items"
Cons: "Almost missed our flight home because American Airlines lost/screwed up our round trip tickets. We were not able to check in quickly or efficiently, & service was appalling, staff was either poorly trained or uneducated. We tried using the kiosk to check in, to avoid the long line. That didn’t work, so we found help. They told us to retry, wasting time, finding out what we had already informed them of. They passed us off to another gate/service counter, who’s line was closed off. So we had to duck the divider. They then redirected us to the kiosks after we informed them it couldn’t find our reservations, so they tried (wasted more time) failed & sent us back to the line we were already in. After that wait we talked to the person at the desk, who also couldn’t find our reservation. They said “I don’t know it’s not in here, what do you want me to do?” I had to tell them to call a manager to get it fixed, we were going to miss our flight. They called & found the problem, then at 3:15ish reissued us tickets for our 3:30 return flight. Still had to get through TSA! There was also NO phone call to hold the plane or to arrange an airport people mover cart. They talked with the TSA agent who told us to go 2 checkpoints down where the line was shorter. So the American Airlines attendant told us to run. Turns out in Miami Airport there is almost a quarter mile of poorly labeled counter space. Went through TSA having 12 min before our reassigned flight left. TSA was helpful, & did their best to get us through quickly. We were then informed we were near gate 22 & our gate was 3, so rushing down another concourse we barely made our return flight home. Where we were forced to check our carry-on. My girlfriend was crying, we were sweaty (from hustling when we never should of had too), hungry, embarrassed, enraged, & not sitting together for our 3+ hr flight! Unacceptable after a 4hr drive to the airport in traffic & returning the rental car at 1:40!"

Pros: "Great Wifi! After reading bad reviews it was actually ok. Flew business on the A319 (single aisle plane) and it reminded me of qantas 737. I think for a short haul day flight I may just put up with economy instead for the price. Food is ok. I think with AA you have to pick your aircraft, it makes a difference what plane you fly as to what you get in business class. FA's were great. Overall I'd fly them again. Food was ok."
Cons: "They asked everyone to put the window shades down but I fly window seat because I like looking out! It was a day flight too! LAX T4 lounge is being refurbished so you need to go to T5 and make sure it's not the regional lounge!"

Pros: "Arrived 20 min early. Smooth flight."
Cons: "Didn’t have individual movie screens."

Pros: "Crew did their best!"
Cons: "Our flight was delayed over 3 hours. Other Advantage members have already received bonus miles for their inconvenience. I am also an Advantage member and have not received bonus points and am unable to get ahold of anyone."

Pros: "The flight left on time. Pleasant crew."
Cons: "As usual, the seats for a 6'4" guy are not good."

Pros: "Nothing"
Cons: "All. Disappointed to see Etihad airlines declining so rapidly. What used to be my preferred airlines, not anymore and definitely can predict the downfall."

Cons: "The a.c didn't work and it was really hott in the aircraft."

Pros: "Comfortable flight. Great communication from pilots, and the service was great."
Cons: "Very old fashioned plane, with one tv to watch a movie. I don't think I've flown on anything like that since the 90's."

Pros: "No drama- always great flying from Long Beach"
Cons: "Really wish that there were power adaptors. Landed with a dead battery."

Pros: "Crew was friendly and helpful. Offered ice after I burned and blistered my finger on the overhead light because it was so hot because it was so old. Pilot got me safely to my destination."
Cons: "-A line of agents asking for passports to even enter the area where American Airlines is located. Crazy security for no reason. -Tiny seats -No legroom for an 8 hour flight -No creature comforts or modern day technology like personal TV's or charging ports. Only 3 Small TV's along the the middle aisle. I remember flying on a plane like this in 1986. Played movies from 2012. Smurfs? Really? -No headphones offered -Burned my finger on the overhead light!!! Still have a blister!"

Cons: "The flight leg PHL-LIS was the most unconfortable transatlantic trip I ever experienced. The plane was small, tight and no head support made this the worst transatlantic flight of my life, easily comparable to any low cost airline."

Pros: "On time"
Cons: "Terrible entertainment. A 1980s common screen. Horrible movies nobody wanted to watch and no choice was available given the common screen,"

Pros: "Getting out of the plane! and the landing was very good."
Cons: "Bad service no entertainment besides a one very childish movie. My tray stayed with me the whole flight, I had almost to beg to take it and never s flight attendant seem happy, pleasant or even profissional. The landing by the pilots was amazing."

Pros: "The only reason I was able to make this flight was that it, too, was delayed. We received ZERO notification - as we were running from one plane to another from Concourse A to B - that the Phoenix-LA flight was delayed. I mean how difficult is that to do?"
Cons: "We took off. We landed. We didn't crash. We sat on the runway for nearly an hour. So much fun!"

Pros: "Not much."
Cons: "There are NO ENTERTAINMENT, and I had two flights that were more than 5 hours each. It was not operated by British, it was actually American Airlines."

Pros: "Plenty empty seats, so I had enough room. Arrival earlier than scheduled, crew provided good service"
Cons: "Food (I had pasta)was lousy, the little TV screen was EXTREMELY unresponsive, Most of the time it would not work - unable to make selections. Seat 19C"

Cons: "The usual delays out of O'Hare. This plane was an older plane, but good enough for a medium length flight."

Pros: "Crew and promptness"
Cons: "No entertainment for each seat. No cellphone charger."

Pros: "The flight had a delay of 4 hours in Philadelphia. I missed the appointment in Lisbon for which I was flying in the first place. Furthermore, I had purchased the ticket with the intent of flying with British Airways and found myself in a charter from American Airlines. I wish to be compensated for this mistake. Thank you"

Pros: "Boarding was fast and easy gate agents were awesome."
Cons: "Older plane. Very uncomfortable"

Pros: "I liked the boarding, entertainment, and food."
Cons: "I did not like the cramped legroom. The airline got greedy and crammed too many rows of seats in the plane, cramping the legroom for all the economy passengers. Legroom in economy was MUCH better on the Japan Airlines plane (also a 777) that I was on from Los Angeles to Japan. Legroom is always important, but especially so on long trans oceanic flights. I am inclined to avoid American Airlines in the future because of that.qa"

Cons: "No wi Fi available and I paid for an all day pass"

Pros: "Flights were on-time, planes were clean/newer, snacks were good."
Cons: "Their boarding/de-boarding process was quite inefficient - they have boarding zones, but then you just go to a shuttle and it's a free for all at the plane."

Pros: "Ordinary flight, not too chaotic for holiday weekend."
Cons: "My luggage was lost! Had to wait an entire day to recuperate my suitcases."

Pros: "It was quick and we had a smooth landing...."
Cons: "Upon arriving in Lima, Avianca 808 passengers became aware that none (zero, nada) of the bags were loaded onto the plane in Cusco. The customer service response to this airline error was sub-par. Passengers were told that the baggage issue was "weather-related", which is ludicrous even if the weather both in origin and destination had not been clear and sunny with no wind (it was). Info was taken on if passengers needed bags sent on to another destination or to a hotel but were told it would not get to Lima until the next morning (this was flight 808 landing just before 4 pm). Unclear why it couldn't be put on the next flight same day. And unclear what is happening to our bags now until the morning. No apology wasn't issued to passengers. Additionally we were delayed 15 mins due to "weather". I don't mind short delays but it was absolutely not weather-related. Weather is the default excuse to transfer fault away from themselves."

Pros: "I booked the flight specifically because it was advertised and booked on British Airways, which is considered a nice international airline to fly. The flight was swaped to American Airlines, and I was put on an international flight that was archaic, I would have been better off flying a prop plane from the 1970's."

Pros: "Crew was efficient and helpful. Captain kept us posted along the way. They also keep air flowing when we were delayed to take off so everyone is comfortable inside the crowded cabin."
Cons: "Crew should try to wake me up for meals. Luckily my fellow passengers did. Otherwise I would have missed all my meals."

Cons: "The bathroom on the flight from Denver to Santa Barbara was the WORST EVER! I doubt it has ever been cleaned and the poor people that had seats near or at the rear of the plane should have been refunded their money having been subjected to the smell of an “indoor outhouse!” Shameful!!"

Pros: "The range of 'free' food and beverages (including beer, wine, and liquor was phenomenal, and the functionality of the 777 touch-screen was outstanding. Seating was also more comfortable than comparable flights on AA."

Cons: "arrived 24 hours late. had to stay overnight in Newark. And United lost our luggage. The worst trip I have ever had."

Pros: "Good flight, decent crew. Food was okay."
Cons: "My entertainment set didn't work because the headphone jack was broken so that was a major bummer."

Pros: "Nothing, absolutely horrible. This is why I fly Southwest and Alaska Airlines as much as possible."
Cons: "Everything. Mechanical delay missed connection, arrived at gate to see plane being pushed off due to delay. They couldn't have waited 5 minutes? Multiple people missed their connecting flights within minutes. They kept us on the plane in Boise then deplaned and re-boarded. No coffee on flight."

Cons: "Some of the entertainment screens were inoperative. The occupied light for the forward restroom (in business class) was not working so you never knew if it was free or not."

Pros: "It didn’t happen."
Cons: "Because of the late plane and possible missed connection, I was re-booked for the next day without any compensation."

Pros: "On time departure and arrival and a friendly crew helped keep this flight smooth despite some turbulence. The fact that there have been electrical outlets on this route for so long is a testimony to the Continental heritage."
Cons: "The seats in economy are just so tight that sleep on this short overnight flight was almost impossible. The lack of more recline (as in the recarro sears used on the LH/LX products) and short pitch make it hard to either work or sleep. The small plane size makes this sardine feeling worse and slows service to the rear of be craft."

Pros: "I travel a lot. All was fairly normal."
Cons: "Entertainment didn’t work. Woman next to me sat cross legged and the bottom of her foot as resting on me. When I politely asked that she not out the bottom of her dirt against me she swore at me and was confrontational and crazy. Flight attendants did nothing"

Pros: "Glad they had a direct flight."
Cons: "The seats didn't offer much room."

Pros: "Very pleasant attentive crew and ground staff. An aborted takeoff on tarmac meant a return to the departure gate and the plane taken to maintenance. The ground staff were superb in dealing with a full plane load of passengers many of whom had onward connections. This meant we had to stay overnight and fly first thing the next morning. Full marks to United for dealing with a potentially dangerous situation and then assisting everyone back in the terminal."

Pros: "Not much."
Cons: "Little to no updates and wrong information when finally given. I was bumped out of my premium seat. I had to ask for refunds for the upgrade and priority seating they were not offered. And I had to ask for a meal voucher since none was offered. Alaska always has offered fist no asking needed."

Pros: "I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours"
Cons: "They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later"

Pros: "Friendly crew."
Cons: "Had a mechanical issue we were told didn't need fixed to fly the plane. Took 1 hour and 20 minutes to complete safety checklist so we could take off. We missed our connecting flight to Cancun."

Pros: "the crew was very friendly and the flight was smooth"

Pros: "We got to Lisbon"
Cons: "The entertainment system in 36E didn't work. The sound in 36D what a lot of noise (it made it unusable)."

Cons: "Flight was delayed. Super small aircraft so suitcases didn't fit. Didn't have food options, just pretzels."

Pros: "The check in with united was rather disappointing. The staff working with united were not clear with instructions and rather rude. Checking in can be a rather stressful process when there are long lines and tons of people.... this person was just short, unclear and rude."
Cons: "Please see above"

Cons: "Zero regard for customer service. I will never fly United Airlines again, I may never use Kayak again either. This was the worst travel experience of my entire life."

Pros: "Nothing"
Cons: "Was told at check in that my flight was delayed and would not make my destination today. When I asked if there was another flight I could get on, they told me the upgrade would be over $1000, and that it wasn't their problem. Rudest customer service I think I have ever dealt with! I won't ever fly united again!"

Pros: "More fights to choose"
Cons: "Could not choose the seat at the time booking"

Pros: "That we got to Little Rock early"
Cons: "I had ordered ginger rail and the lady brought me a Diet Coke I told her I don't like Diet Coke because I don't drink Coke and she said I thought that's what you want it now you have to hold onto it until they come back and pick up the trash and she never brought me the ginger rail to drink she walked away and I never drank nothing on the flight back to Little Rock that lady was so rude"

Cons: "Food, like all airlines, is so lacking even though airlines are making record profits while lessening service (crowded, fewer flights, baggage fees, etc)."

Pros: "Great staff and everything on time"

Pros: "Nothing"
Cons: "That a bunch of travelers including myself missed our connecting flight in Chicago after united chamged our arrival gate but didn't have any crew to man the jet way. We sat for 20 mins right in front of our gate. From 1 pm to 10 on my flight to Asheville from Chicago was delayed many many times waiting for our airplane to arrive. Upsetting that we missed our connection due to United's poor planning, they didn't hold our connecting flight for us but we had to wait all night for other flights."

Pros: "It was so smooth.No long lines ,no delays,a straight thru flight.And on Christmas Eve morning."

Pros: "The travel agent, Tim, in STL worked very hard to get us on a flight."
Cons: "After a cancelled flight, two delays and lost luggage (that we did not receive for two days after arrival) on the way to Boise, we've now been cancelled on the way home to St. Louis. The first cancellation was due to weather. The two delays were due to late crew and refueling issues. Today's cancellation was due to maintenance. Embarassing. I travel often and can guarantee I will never fly United again."

Pros: "we left right on time. It was a smooth flight and a nice aircraft. did not use entertainment so no comment there but was a good experience overall."

Pros: "Attendants were nice."
Cons: "I booked the comfort economy seating that I normally do with Delta. With their additional cost you get a larger seating area, free in-flight movies, reserved compartment space for your carry on and a free drink. No such thing with United. They did try to have movies through their app, but it wouldn't play long enough to allow you to watch."

Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."

Cons: "Cancelled and rebooked on a different airline with a long layover."

Pros: "Crew"
Cons: "I think that after first class they should load the plane from the last seat forward for ease of getting to the back seats"

Cons: "Charged 50.00 for check bags,when that was included in the online purchase,not happy and probably will not use either again!"

Pros: "prompt emails and text messages with the back up plan"
Cons: "Missed connecting flight because flight delayed takeoff from home due to SFO problems. Sat on tarmac for an hour or more, finally took off but missed connecting flight mid afternoon and no other acceptable flights until 11 pm getting into Fort Lauderdale at 730 am. (originally was supposed to be getting to Fort Lauderdale at 10 pm). Also, the aisle seats on the plane had a narrower underseat space that my little boxy carryon wouldn't fit into--and it usually fits under any underseat storage...Luckily the passenger in the middle was willing to swap places."

Pros: "Overall it was a great experience. Will travel on United again in the near future"

Pros: "Boarding on time"
Cons: "Headphone jack was broken Beer on the first flight was free, on the return cost 7 dollars"

Pros: "Flight to Austin was just fine."
Cons: "My flight back to bosie from San Francisco they changed the gate I didn't hear the change and missed my flight. I didn't get back to bosie until the next day."

Pros: "Nothing"
Cons: "United are the most rudest phone people on the phone to deal with and if it's there fault they never want to comp u last time I fly with united"

Pros: "Flight was on time"
Cons: "That u load the plane assistance backard,loading goes much faster if you start @the back of the plane,& myself I carry only a shoulder bag only ,all the time. U put me @ the back of the plane 90% of the time which means I have to wait for the people that are moving their whole house,making me miss my schedule, I have to spend night @ airport for next schedule."

Cons: "no inflight entertainment."

Pros: "Not only do I get the best price. The fact that you told me what carousel to get my bag from was new to me. I alway check kyak first but now I love u guys. I know my travel site and its kayak"
