The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

everything was pretty good. Houston airport is awful. Unnecessarily inefficient; people working there are rude. Badly run

Staff on board was excellent. Positive upbeat helpful- like it used to be.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

We were happy with the service and cost of checking a bag

Flying with Air Canada is still better than the discount airlines like Flair. The seats are more comfortable and the on-board entertainment is better, with each seat having a built in screen and lots of content to watch. Onboard WIFI is also great to have, as well as plugs for charging. I think passengers in general are getting better at not bringing too much luggage onboard, and Air Canada is better at managing this without customers feeling like they are being taken advantage of with extra fees. I have travelled on different airlines and all seem to be loading faster, with fewer people bringing both a carry on and a personal item. Now I just bring one item and it fits under the seat so I don't need to worry about finding a place in the overhead bins. Overall, across the industry, asking customers to pay for carry on baggage is fair because it allows customers to only pay for what they need, and it helps to keep the planes on time. Kudos to Air Canada for its approach - the desired result is achieved without customers feeling that they are being surprised and caught with unexpected extra fees.

Due to the strike by AC flight attendants, my flight was cancelled. Very disappointing! A refund is being processed. This was not a Kayak issue. I will be sure to come back to Kayak in the future.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

Great flights. 90 minute departure delay for maintenance issues, not a great start but, afer that very good. Didn't pay extra for seats and lucked into a window and an aisle seat. Price was excellent at the super low economy level.

Just a little improvement on food but everything is excellent

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.
