Look at Jet Blue and Delta. May be a bit more expensive but keep an eye out for fare reductions and book early.

Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.

Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).

Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.

Go to the airport early, LAX is the worst airport to fly out from. There is just so much traffic on the way to get there. We used the flyaway option in van nuys, ( buy your parking ticket in advance) costing us only 115 dollars for parking for over two weeks and it’s very secure. The buses go every 15 minutes from there directly to LAX. Best way to get to and from LAX. Check in was easy.

JFK is an amazing airport, they have TSA precheck which was not offered when I flew Aer Lingus/Newark. The TSA precheck line took a long time, they only had 2 machines and a few agents working. Other than that Newark was as any other airport, easy bag check in process and gate seating area was clean and comfortable.

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

Flights were on time actually early service was good and crew cheerful

I had a good time. However, I paid for the wifi and it was in and out the whole flight.

we did a return flight from Paris CDG to SFO. This trip was much better than the departing flight SFO to CDG. The food was better quality, the crew was nicer, and the interior of the plane seemed cleaner.

Flight to Japan was was better across the board than the return to USA. Entertainment: Movie selection was old and not to my liking. Way too many woke choices. Not enough selections for sports or drama. Service: some of the crew were great. Not all. I paid for business class. a premium. Some of the crew thought they 'had' t do there job instead of wanting to serve and be polite. Food: Way to Japan was good. Way back to USA bad. Boarding: Wat out did not offer Business only; had to go thru general. If you pay for business, you should get business perks. Suggest you look for other than United for travel to Asia

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Absolutely terrible. I booked my ticket with ANA and underpricer/kayak asked me to change all my return flights to United. Customer service does not exist with United. Flight attendants are rude, self-centered, and unhelpful. The food is served cold and uncovered. The in-flight video controllers do not work properly. Premier economy tickets with ANA, allow you access to all airport lounges, while United does not allow access to any lounge. Mockery of an airline.

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

Aircraft was noisy, old and never dimmed the lights on a night flight even on business class! I flew 17 times on United and probably another 40 on other airlines United USA /Europe flights were the worst to include luggage delayed once going to europe and once coming back

This was an older airplane. The cabin was constantly warm to hot throughout the 10 hour flight and there were no vents to personalize air flow. Also since it was an older plane, the material and comfort of the chairs were very uncomfortable. I left my flight with major soreness on my tailbone.

This was the smoothest flight I've ever taken with any airline, including Aer Lingus. Typically, there are moments when I feel afraid, but from take off (miraculously seamless!) to cruise, to landing this was a perfect flight. Thank you!

Poor. Plane left EWR late hence missed connecting flight in Dublin. No pro active info from flight staff on connection, only when probed a couple of lies on where we would dock, and on lilelyhood catching connecting flight. Lies as they will have known our EWR-DUB would be parked furthest away from the transit spit - lying it would be next to the AMS flight.

The seat area was way too compact. The person in front reclined, and the TV screen was right in my face. There was a metal box secured to the floor in my foot area, further limiting space. Food was OK. The last service was provided too late in the flight, so the crew was rushing at the end. The ticket counter in the Naples airport was extremely slow. The staff on the flight was friendly.

delayed flight stayed whole night at washington Dallas airport at seats , uncomfortable . i am senior citizen , very tired , worst travel.

I heard that the pilots were actually leprechauns, but I was not able to confirm. Can you please provide documentation if this is true?

The check in process at the front desk felt slow and it was frustrating that we could not check in online. Everything about the actual flight was great, including very kind flight attendants and a nice larger bathroom. Only thing is that it was very cold in the plane!

I flew economy class. Seats were very good and the crew was excellent

I had a great experience. I would definitely use them again

The pre-check (passport control) for all US flights from Dublin airport is brilliant, meaning these flights come into the domestic airport in the US - it was so quick and easy getting to my hotel once we landed. The plane itself was great, staff were lovely and food was fine.

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

The flight was delayed 4 hours and the JetBlue people at the counter kept lying to us and telling us it was due to weather however all other flights were going in and out of NY and FL. Then they lied that the plane had to stop to refuel. Then they lied and said the plane needed a tire change. JetBlue is the worst. Then they gave a lot of people meal vouchers however I didn’t know they did that and they didn’t offer anything to me.

Entertainment and wifi were very sub-par - audio issues and no wifi

They made me check my bag and I didn't need to as there was overhead space available. I paid for a seat towards the front of the plane and it didn't recline. I requested a refund and they declined to give me one.

We were made to wait in the airport for six hours for a flight that was ultimately canceled.

Both flights were significantly delayed. The flight experience itself was great.

The crew for the flight was A+ top notch. They were friendly and professional and made the flight a very relaxing and enjoable.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

Our flight was delayed 5 hours, very disorganized, bad communication, confusion. Only good thing was the crew.

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

Real smooth and easy, Real good leg room in coach!

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.

Very good except paying twice for seat selection. Once when I booked and again when I checked in.

No TV's. Seats are super uncomfortable. Crew was great!

Terrible confusion btw air Canada and United. Wasn’t able to change ticket because I had purchased on kayak. Rethinking booking tickets on this site, and will try to avoid United and aircanada going forward.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

The flight was delayed to 1:50 am from 12:05am which caused confusion for us on the connecting flight.

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

Great flight, last one out the air-conditioning was far to hot and the return it was to cold and then issued blankets. On the outward bowned the headset connector didn't work properly. You had intermittent sound from the audio socket.

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Crew was good. Seat was worn but overall okay. The infotainment system is outdated and needs to be updated. BA should provide free WiFi for club world/business class passengers.

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

Entertainment system didn't work well. Also no new movies and limited choice of other programmes. . And only one USB A charger option. Most modern electronic items needs USB C. Planes should offer both

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠
