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.

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.

Delayed, toilets did not flush, pilot parked to far away from Gate

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.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

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.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

One of the best flight experience I have had in along time. Would fly with them again.

Like getting a bus. No great luxury but will get you there

Flight was good, crew was excellent. No complaints at all

Friendly, professional. Everything went smoothly and pretty much on schedule.

Leaving the same day as planned would've been better

No internet, not even westjet connect makes for a boring flight

Our first flight from LAX to Winnipeg was changed but you never informed us at all. It went from a nonstop flight to a stay at Calgary. This impacted our trip negatively as we arrived much later than we planned to. Our returning flight was horrible. The flight was delayed 6 hours!! And we were NOT going to wait that long. The only way we got on our original flight was running there. However all of our suitcases were now coming on the delayed flight. It was the worst experience we ever had flying. I want my money back.

Be on time late arrival missed connection arrived five hours late to destination

Missed the connection due to previous flight delay. Can't rate a flight I was not on

Everything was good except I was a bit disappointed that I had to pay US $150 for bags.

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

Price was good. Entertainment and food could have been better

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.

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.

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 😠

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

I was put into business class. Wow! My flight attendant was great! The food amazing’
