12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

The ladies are great seats should be a little bigger!

Couple of hours delayed, we had to re-booked our Shinkansen reservation twice. United Aiines need to improve their time!

The flight was direct, anytime a flight is on time, and there's not a layover that risk yet another delay is a win!!

Staff on the flight were terse, bossy, and impatient with people on the plane.

The crew was excellent. We brought our own snacks due to dietary requirements and personal preference. There was an ample beverage selection. The seating was comfortable enough. My only complaint was that there was no announcement, or at least none that we could hear, that our connecting flight was departing from a different terminal. That could been announced by the air crew in flight or before disembarking.

Although delayed an hour, the gate attendants kept us notified and the rest of the trip went off with no issues.

We showed up to our gate less than 15 minutes after boarding started and they wouldn’t let us in. It was still 15 minutes even before take off so we’re weren’t even late to the flight.

When I checked in with full service, requesting a wheelchair, as I had asked for ahead of time, the customer service agent said “wait over there, nothing more. I waited in the designated space for about 40 minutes before learning from another passenger that I needed to check in again at a specific assistance desk. I was early, so I made it on time to my flight. Your agent should not assume I knew anything, which I didn’t. This was all new, in a recently remodeled space. New to me, anyway.

Great trip. No complaints. Impressed with the crew’s response to various challenges pre-boarding.

We were 35 minutes late because the caterer had not stocked the plane. Plane was fully loaded and ready to go 15 minutes before departure time. We sat there 35 minutes?

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

I flew standby with my two children and completely forgot it was Memorial Day weekend. We tried to fly from PDX to YVR. Unfortunately, after four attempts, we gave up and tried SEA instead after the holiday. The ground crew was very helpful, checking us in and accommodating us when we were finally able to get on a flight. The sad part was that they accidentally loaded one of my suitcases on the Vancouver flight without us during one of our attempts to get on a flight, even though it had a standby tag on it. I filed a report with baggage services, and thankfully, it was returned to PDX the following day. AS was in touch with us and updated us on the process of returning the luggage to the USA.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

Crew was great. Friendly, calm, interesting, happy to be there. That makes a huge difference. Plane was very quiet. Also quite empty so I had three seats to sleep across

The flights were on time- Great service Would have liked more options for food choices.

I’ve been on this flight 4 times in the last year for work and the food never changes and always has my stomach upset by the end of the flight. The cold salad with dinner is never a fan favorite with my traveling team.

The brakes on the A220 are sensitive and uncomfortably grabby

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.

It was pretty straight forward, no glitches or hidden costs

The whole plane smelled and felt old. The seats were very uncomfortable. Multiple delays. Extra fees.

For goodness sake, board from the back of the plane to the front and assign overhead space. It would fix everything. Seriously.

Aircraft had technical issues. After 3 hours of trying to resolve, flight was cancelled. Was booked on a flight leaving 12 hours after intended departure. Now on 4 flights instead of 2 and a day late to my destination.

PDX staff was great and we arrived on time in YVR.

Horrible I had a health emergency and couldn’t go Air Canada refused to allow me to reschedule

Really poor travel experience. My first flight was cancelled, which cut my international trip short and threw off my schedule. I will not be flying Air Canada again if I can so help it. The crew and in-flight experience was pleasant and enjoyable but the consistent delays and cancellations are not worth it.

Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.

The staff were condescending and withheld at times. There were times when they appeared to be more concerned with socializing with each other than appearing professional. I know it must be a hard job, but being chatty and handsy with each other in the public view only to be condescending to customers isn’t a good look.

No entertainment what’s so ever so you may want to prepare yourself. Our flight was delayed.
