Reviews of the top 5 airlines flying to the United States
The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.
Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,
Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)
Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.
This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any
I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional
Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.
It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.
We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.
Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.
Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.
Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight
First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.
Please stop those idiotic and unrelenting announcements, commercials and stupid credit card drivel. All together about 15 minutes of stupidness that annoys each passenger.
On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.
Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.
The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.
Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.
If other people in flight, followed instructions and were much cleaner.
Didn’t have requested food and seats could be more comfortable.
Flight attendants on this flight were very lovely. Hot food was terrible. Canned wine felt elevated and was GOOD. The aircraft was overall not very clean. Although this one was much more cleanly than the flight from Pisa. Pilots were great & landings felt smooth and safe. As I mentioned in my last review, this was my first time flying aer Lingus in many years and I cannot say I will be rushing to book again. This airline needs a real facelift.
Everything went extremely smoothly! They boarded by groupings of seat numbers starting from back to front. All staff very helpful and accommodating. Food and beverage plentiful and good.
The plane from Venice to Dublin ran out of food. They did not restock the plane in Venice.
It was very refreshing being in a nice and clean plain, with pillows and earphones that you don’t have to pay for, with warm food and beverages and a very nice crew
The thing thy call a pizza was atrocious. Do not eat it. The seating is as usual for economy an experiment in cruel and unusual punishment that they aren't allowed to do to prisoners but you get to pay for it.
Didn't make it to this flight as we sat on the tarmac for 1.5 hours.
The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.
Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly
I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak
My overall experience with JetBlue was pretty poor and disappointing. We originally booked a DIRECT flight home from Boston on 9/28 at 8:00pm even though it cost more than the non direct flights. With no reason other than "unforeseen circumstances", our flight home Monday was cancelled and we were rebooked on a 7:00am flight on 9/29 with a layover in JFK. We were traveling with sick kids coming home from a funeral of a loved one and needed to be at work on Tuesday so paying extra for a flight home Monday was something we had to do. The original direct flights were considerably more expensive than the non direct flights- so I don't understand how Jetblue did absolutely NOTHING to compensate or right their mistake. We will not be booking with them in the future because they are not reliable and they showed no remorse nor did they make any attempt to make things right. The least they could have done was credit the difference in cost of flight because I know our original flights cost more than the one we were rebooked on. Once again- we will not be flying with them in the future and will advise family and friends to be aware of the risk you run when giving them your business. Do better.
The flight attendant was snarky and the flight took off very late. I know it was an issue with air traffic control and the runways in Boston, so not really anyone's fault, but very frustrating, I missed an important meeting because of rgr delay. They didn't offer headphones to watch the TV, but luckily I remembered my own and was able to enjoy watching a movie.
Terrible. We originally booked a direct flight from BOS to MCO on 9/28 at 8:00pm and it was cancelled due to unforeseen circumstances and the flight we were rebooked on was on 9/29 at 7:00am with a layover in JFK. We were traveling with sick kids so leaving at such an early hour was absolutely miserable, and on top of that we all missed work which we couldn’t afford. On top of that- we paid a fortune for our flights to be direct without a layover and the flights with layovers were cheaper so at the very minimum we should have been refunded the difference. With absolutely no explanation or sympathy from JetBlue- we will avoid using them in the future due to the fact they aren’t reliable nor do they correct their mistakes.
Experience with JetBlue was poor. We were originally suppose to fly home on a direct flight on Monday the 28th at 8:00pm and we it was canceled due to “unforeseen circumstances” and we were rebooked on a 7am flight on Tuesday the 29th with a layover in JFK. Traveling with sick kids and waking up at an ungodly hour was miserable, and not only that it caused all of us to miss work. We intentionally flew our Monday on a direct flight and the direct flight was far more than the non direct flights on any given day. There was no compensation provided let alone a reasonable explanation. When you are charging people those type of prices for domestic same coast flights- you should be at least refunding the cost difference of the flights if you are rebooking them on a cheaper flight. I will never fly JetBlue again because they are unreliable and don’t correct their mistakes.
Wasn’t very happy with our flight home due to the fact it was cancelled with absolutely no reason. It was a direct flight at 8:00pm on Monday and they rebooked us for a 7am flight on Tuesday with a layover. Traveling with sick kids, getting up that early was miserable and on top of that we all missed a day of work that we couldn’t afford to with absolutely no apology or compensation from JetBlue. The original cost of the flights were astronomical because we flew out on Monday over Tuesday and also we paid extra for the direct flight then we would have for the flight with a layover. Super disappointed Jetblue truly could have cared less. Will avoid them in the future due to the fact they aren’t reliable nor compassionate for the inconvenience these changes cost their clients.
No WiFi, no power to charge phone, confusing boarding, delays
There is a considerable amount of people that use the wheel chair pre boarding along of large groups of family / friends. This is not right should be limited only to the person in need and the airline assistant. Some of these people use overhead bins that do not belong to them. The aircraft had a non functional wifi . The service was bad.
Flight was delayed 3 hours. No food on plane besides snacks
Every thing went smooth. No complaints except deplaning could have been quicker
I was grossly overcharged to change my return flight. Had to do it through Kayak because it was booked that way and I was not given the fare price listed at the time on JetBlue or kayak. Was traveling with another couple that booked directly through JetBlue and they paid the $100 change fee and the difference between what they paid originally(same as me) and the displayed fares and it was less than $400 total for two tickets. I paid almost $700 to change the same fare tickets they purchased and had to pay again for upgraded seat selection that I previously paid for on top of the almost $700 increase. Difficult to talk to the kayak representative because of his accent. Told me I had to wait for confirmation to be sure it had been changed and that I could take up to a few hours. The call itself after the wait time took almost 30 minutes, which could’ve been done directly on JetBlue in 2 to 3 minutes.. My husband and I were given separate boarding zones. They would not let us board together. I had to board in the last zone. They made me check my bag even though my husband told me that he had a spot to put my carry-on. Since he boarded before me. The flight crew tried to accommodate, but the woman that was boarding in the terminal came down and would not let me take my carry-on. She was aggressive, rude and condescending to everybody in line and told them she was being audited. When I told her that my husband had secured a spot for me to put my carry-on with his backpack, that would then move to under the seat. She told me that she couldn’t play favorites, although I was second to last to board the plane since my boarding zone was changed. They told me because I forwarded my husband his ticket that’s what separated our boarding zones, but would not allow us to board together. The volume on my TV would not work, and my upgraded seat would not go into the fully upright position so I was told repeatedly during takeoff and landing to put my chair into the upright position which was embarrassing and uncomfortable to be told assertively so many times. I will not book through kayak again.
I liked that 5 pound refreshment voucher was given for 1 hr delay. Staff were courteous and professional. I was expecting more for the 2nd meal (pizza). Usually for a long flight, the 2nd meal is something like eggs/sausage/potatoes/fruit/dessert.
The boarding process, airplane, entertainment, beverages and crew were very good. But the food left a lot to be desired, especially for business class. I had a chicken breast that was tough and rubbery, with little flavor. It wasn't even up to the proverbial "banquet chicken" standards. Very disappointing. There was only one offering of bread, OK, not a huge deal, but it's a nice touch to be offered more. Similarly, other airlines' crews come by to offer more drinks, though the crew responded when asked. Good flight overall, but the food just wasn't up to the standards you'd expect.
More options on TV shows and movies and make it where if someone wants to choose their seats that it is an easy process. I wanted to choose our seats and never could do that! I even called and they told me I had to do it with agent at the airport. That was very inconvenient
We were treated politely and the crew was nice. Again no one knew why there was a delay. Food was hot and a lot was offered but bad in taste. Seats weren’t the worst but for a long flight your legs ache from it. Entertainment was old not very interactive
I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.
This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!
WiFi didn’t work for me. as headphones didn’t work either.
Canceled flight for unknown reason after numerous delays and only available flight was the following day yet no compensation. No weather problem. Then had to fill out form to get refund. American used to be a quality airline - no more, very sad!
entertainment choice was excellent for both movies and audio. Food was quite good. Staff was excellent and flight was on time and smooth.
The flight was uneventful, which is always good. The plane was clean and seem to have a little bit more room. They fed us every couple hours, and we had a lot of in-flight entertainment. The staff was very helpful and attentive.
