Gate agent in LAS named Juliett should win an award for excellent customer service.
Gate agent in LAS named Juliett should win an award for excellent customer service.
Gate agent and flight attendants were efficient, but more stern than warm.
The only issue is that the plane was HOT. This was not the case on my first flight so not sure why, but thankfully I had a portable fan with me. Everything else was great!
13 hour delay stuck in Detroit and missed a day of meetings. It was terrible
My flight was so delayed I would ’ve missed my connection and had to cancel my trip
Seemingly unnecessary delays were compounded by a lack of communication from the flight crew which turned a four hour delay into an overly stressful experience.
I like Delta. I dislike the volume of announcements from the crew. They are not always easy to hear and typically repetitive.
I think the crew makes way too many announcements that are: 1) hard to hear in some cases and 2) repetitive. This detracts from entertainment and concentration if working or reading.
Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.
The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.
Good food and entertainment. Poor choices for drinks. Sitting for 12 hours on the row by the restrooms, which do not recline, was a torture
Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice
The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience
Wifi is very frustrating - could not connect and therefore unable to work on the trip
Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.
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
Forced to check bag, even though plenty of space in overhead bins. Did not appreciate having to wait at baggage claim to retrieve suitcase.
Great. I was in mint class. Security was spectacular. A lot of room on the flight! And the WiFi worked this time- it didn’t work the last time and I am on a business trip so that was a problem.
There was more leg room in what was most likely a basic assigned seat (row 25) then on other airlines I've flown lately.
They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.
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
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.
