Cabin Crew was excellent. They took care of everything requested. Flight was good

Cabin Crew was excellent. They took care of everything requested. Flight was good

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

United Airlines crew members do not know how to deal with emergency situation that caused our flight delay. For example, they should have asked the maintenance or seat belt repair personnel to come and fix the seat belt while they were looking for a volunteer to book another flight.

The pilot was kept warning about the weather terrifying us. The flight attendants were not warm or pleasant.

Entertainment and food is best. I love to use ana for a lots japanese movies…. Food was best

I couldn’t sit with my daughter. we are separate and both seat was not window or halway side. in the middle. if we sit together will be share comfort seat and more easy travel. this is bad.

First trip from Tulsa to Houston by air. It went by quickly. I watched half a movie and continued the rest on the next flight. Staff was considerate and helpful.

The meals were sufficient and tasty considering it was air travel food. Water coffee and juices offered each time a meal came by and water distributed between meals. It was good service in my opinion. Plenty of movies to enjoy. May not be the one you want but plenty of older movies and plenty of current ones as well. I enjoyed the trip.

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

toilets could be cleaned more frequently, everything else was pretty good.

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Best service airline. The cabin crew is attentive and friendly. Inflight entertainment system is good

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

Flight was good but there are way to many announcements for credit cards etc.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

I like the pleasantness of how courteous and friendly and helpful everyone is

My luggages were lost and the service attendant was extremely unprofessional. Despite presenting my luggage claim slips, the attendant stated she had “no record” of my bags and made no meaningful effort to assist. When I explained that the luggage contained our family’s complete scuba diving equipment, her response was dismissive, stating that she “didn’t care.” While lost luggage is frustrating on its own, the lack of professionalism and lack of empathy significantly worsened the situation.

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

Flight was good took off on time arrived early. Crew was awesome and did a great job. Very helpful and courteous. Bags arrived super fast with no hassles. Great flight!!!!!!

Many movies do not have captions, which would have been helpful when you have to live with the flight engine noise.

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

Food could of been better. Crew was pretty much average. It was raining a lot on arrival, had to take a bus to immigration building,

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

Crew excellent calling me by name ! Only downside was no inflight WiFi

I was glad that the plane was not totally full.

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight cancellations, delays, mass confusion and disorganization! That’s Air Canada for you, nothing new. I would have chosen a different airline if it were an option, and Air Canada continues to prove they don’t care about their customers.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

The flight from SFO to YVR was delayed and my bag did not make it to my next flight from YVR to SYD. It took almost 3 days after I landed to get my bag and when I got it, it was filled with dust

Our biggest complaint about Air Canada is that if you don’t like your seat during check-in, there’s a fee to move elsewhere. On our flight from YUL to FFL, we were charged to change seats—just regular seats. What’s maddening is that the plane wasn’t even full; there were even a few people sleeping in the middle row sections (entire rows, completely empty), using them as beds. In my opinion, charging passengers for seat changes is a cash grab by Air Canada. They are definitely not the airline they were back in the day. I suppose they need to gouge the consumer now that they pay their attendants while on ground. One out of 10.

Nothing specific. Cabin temperature was too high for some reason.
