I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

worst flight ever from Delta, it got delayed and kept on delaying..

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Overall, terrible. Flight from SFO was delayed due to “air traffic control issues”, and we were all mislead about connecting flights. Told “you have 20 minutes to catch your connection”. Reality was 5. We got to watch the plane sit at the bridge. Won’t fly Delta with a connection again.

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

West Jet has a horrible boarding process and the seats have no cushion.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

Putting people that close to the bathroom, where you have to look into the bathroom as people are exiting and entering was not great and the smell was also not great. I know the airlines are desperate for more chairs, but that seat is a crime.

one staffer was frustrated (it happen); the flight was late and the pilot mentioned they'll make amend but the snacks were the same, other than that the aircraft was clean and everything went smooth, no complaints

ticket agent lady wás very helpful , she arranged wheel chair for my elderly mother

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.

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

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

The free snack options are pretty pitiful for a 2.40h flight.

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

No communication from Kayak or West Jet. Booked extra flights, flights cancelled, no one answers calls. Will be disputing charges.

Leg room is a problem the plane was dirty and there were no movies available on the app

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

Our flight was delayed almost 3.5 hours (some of the issue seemed to be weather-related, yes) but NOTHING was offered as an conciliatory gesture for this delay. No food offering or any additional drink offering. There is no entertainment is available on any screen behind the seats. The airlines are so quick to penalize customers for slightest requests for comfort- seat changes, complicated baggage allowances, seating zones which are utterly dehumanizing (ZONE 9? after Zone 4- why? This is so clearly meant to be a message to those that do not have 'loyalty' to this airline to make a distinguishing line in the sand. There is such a lack of humanity in the way people are corralled in and spoken to. So, I don't think airlines should be all that surprised when those some dehumanizing corporate treatment is returned to them when asked. The flight on the way into Calgary was scheduled to arrived at 9:25 and we arrived at 12:45 AM. It is not okay. I would think TWICE and possibly once more before booking with them again. Their overhead bins are small and limited so they bully you into either paying for a $90 checked bag or gate check a lot of people's bags. Often on their website there is no carry-on bag allowance. Beware!

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

They were on time and everything went as expected. The only thing that could be better was they didn't wait for us to get through customs to pick up our luggage off the carousel. An employee picked it up and was shoving it together with others onto a cart. Later we found one of our luggage was slightly bent.

Only issue was checking in took over an hour and was very stressful. It all worked out, but we weren't sure for a while.

Multiple delays and flight cancellations meant that I arrived five and a half hours late at my destination. There was limited communication from the airline. The airline left my checked bag at my departure city and stopped tracking it almost immediately. The airline has made no apparent effort to return my bag despite filing a report, and has provided no communication or ability to check on the status of the bag.

Internet wouldn’t work even after I paid for the package. That was my only real complaint, otherwise excellent.

Flight was on time, staff worked hard to accommodate passengers, Efficient smooth flight, One washroom out of order but not a significant issue Easy short 3 hour flight

Seats were small and uncomfortable my seat was Broken and didn’t lean back

The one review I made last I thought was from Houston to calgary so go off that one

From San Francisco to Calgary the seats were uncomfortable. We wish they could lean a bit back.

Check-in was excellent. Flight crew were average, but managed the weather induced stress calmly. We were delayed five hours due to weather, equipment, and staffing shortages.

Flight attendants were super, pilot did a great take off and landing, all in all “Great flight”

Flight was delayed, connection was missed, Airline failed to follow Canadian Customs and Border rules which could of resulted in the loss of personal property, fine or possibly being arrested. Gates for departures were suddenly changed, and airline lost my clothing and a cased firearm. I have also lost a day of hunting with an outfitter to the tune of $875 per day. Think I’m upset, do not under any circumstances use this airline.

Maple Leaf Lounge morning food could be more carried and substantial. All AC portion well managed, clean and on schedule
