Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I missed my flight and had to buy new tickets Rome- Boston

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

Referencing ANA'S service to Japan and the return on UA, the pillow was awful, the crew was not very attentive, and the food was bizarre and tasted okay. Whoever's idea it was to make vegetable tempera in a steam capsule should probably revisit that. Since it was the vegetarian option, it was my only choice.

Crew was great! Good meals. Had room to stretch out

Our flight was delayed 2.5 hours from Lisbon to DC so we missed our connection to Seattle that would have arrived at about 9 PM. The agent initially said we had to stay overnight in DC and there were no other options to put us on to get us to Seattle. While on board I discovered a flight via American he could have put us in but by the time we arrived in DC that was sold out. We were then put on a flight to San Francisco that was also delayed then arrived in San Francisco and our flight to Seattle was also delayed so we ended up not arriving until 2:15 am. Our son could not pick us up so we ended up having to pay over $100 to Uber home. This is the second trip with United that the flight has been delayed causing us to miss an evening in Las Vegas and we were given nothing.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

gave me complimentary food as the flight was not full and was attentive to my needs

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Never flown with Air Canada before, but it's now a top choice! Loved it!

Horrible crew, horrible seats configuration, ridiculous space in the toilets, Air Canada is no longer a option.

Crew at gate and onboard were just very OK, not very friendly and honestly seemed bothered to be there. I will give a shout out to still selling headphones for those who forgot.

Flight Boarded and departed on time. The Flight crew was very friendly and accommodating. The aircraft was clean and free from clutter and debris. I will be happy to recommend Air Canada to my friends and relatives for their flight needs. They were very attentive and responsive to our needs as Senior citizens.
