We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

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!!!!

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

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.

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

The brakes on the A220 are sensitive and uncomfortably grabby

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

Very good overall. However, your choices of free movies was limited and there was no music Channel???

This was the worst flight I’ve been on. Getting on the plane where is was 30 degrees outside was hotter on board cabin must’ve been 33 degrees. This is a health hazard. They cannot be doing this to save on fuel. People could die from this!!. Fans and a/c was, off entertainment was off. Poor excuse given. Crew made the excuse that the system didn’t have enough power. They basically were operating on one engine to save on jet fuel till 3 hours later on cruising altitude and they then started the second engine. And finally the cabin was cooled. On a 7hour red eye flight this made it so uncomfortable and impossible to sleep.

One of the best Qantas business flights I've had. Quality product

I disliked the fact that they forced people to put up their seats during meal service

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

Boarding was terrible - the ground staff member Fredeya at lax was more military than customer service, have never encountered a customer service representative as rude as her. Apart from that all other staff were wonderful and the flight was good.

I travelled first class from LAX to MEL and it was a series of disasters which I put down to lax staff who dont care and a suck it attitude to customers - its all lip service and no delivery. The flight was delayed due to aircraft refuellers putting on 300,000 litres of fuel on a 380Q1. I entered via the first class bridge loaded my bags in the overhead locker. the lady in the next isle in first class also had hers in there as she wasn't allocated a locker over her seat. The attendant asked would I like a champagne - I said yes please. he promptly delivered a empty glass and the glass left on the desk. Then he ignored me for 20 minutes. When i asked him is he out of champagne he gave me the usual rubbish I was distracted. There are four staff and 15 first class passengers - give me a break. the glass stayed there on takeoff and then was still there 9 hours into the flight. When I arrived to my seat I told him I had eaten and wouldn't be eating on the flight - it was 10.30pm. Yet he comes by later 4am ( I happen to be awake) and says are you eating with us? I asked for the bed to be made up - they put a 3 inch 7cm mattress on the chair but as usual the break in the chair - the mattress sinks into it - so I had to move it around so I didnt get my back sunk in the V - Im 187cm tall. The cabinet next to 1K is for staff bags and the toilet is next door. I tried to avoid this seat but couldn't change - in to the flight 8 hours and the cabin rest change over kicks in - this attendant is shining his torch in my eyes taking out and returning his bag. Then the toilet starts flushing and forget trying to get to sleep. Yet no-one else needed torch! 11 hours into the 15.5 hour flight I ask for breakfast - I order two poached eggs, bacon on multigrain toast, tomatos and mushrooms. I get no bacon or toast and have to order it and the eggs are cold. Then I order a coffee which is so badly spilled - and not by air turbulence she brings back a serviette and replaces the first one rather than providing a clean dry saucer! First class in Qantas is a joke as the staff just don't get the meaning of prompt service and attention to detail. I will fly business class rather than first on Qantas as its better value for money but I have been very impressed with United First Polaris and given I fly internationally every month this is going to be my choice.

I was in premium economy. My seat didn’t recline much - it was broken. My phone charger didn’t work.

The business-class pajamas, though thin, and the mattress pad were much appreciated. This plane had adjustable air vents and enough room in the forward galley for me to stretch between meals.

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.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

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

My flight was delayed for a whole day, so I lost a day of my vacation.

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.

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.
