After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

The WiFi didn't seem as fast as it normally is

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

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.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Typical flying experience in the US. Nothing particularly good or bad.

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.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

It was reasonably comfortable trip considering its duration (7 hours). Crew was very good and friendly, seats very more comfortable than other planes. Only negative comment would be that the bathroom light did not get its full brightness 🙃

The flight was delayed about 4 hours without any explanation. No wifi or entertainment at all on planes. Had to pay for checked bags I was allowed according to reservations.

It was good, plane is a bit older so seats are somewhat flat

Great from check in all the way to the end. Very happy with Copa

Copa stranded us ans then tried to charge us thousands to leave Panama.

I loved my experience. Very safe, Very informative and very friendly.

At JFK the Security line was extremely long and few checkpoints open.

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

My suitcase was completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Liked nothing. As per previous segment it was delay delay delay.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Most disapointing experience. We were rerouted to Toronto, after a 7 hours flight , where we sat on the tarmac for a little over 4 hours, in a full airplain with no air. We were given a tiny cup of water twice during that wait. After the long wait we taxi out of toronto to wait another 30 min. Many people missed their conections including my kids and I. We were promised a hotel room in Montreal on the aircraft and at the exit of the aircraft, then directed to a desk after custom where me and my two kids were told that we do not get a room for the night and that we were on our own, after a back and fourth and stating what was told to us, the agent at the counter says that we are right and that we should have a room. I ask the lady if she could look into a different flight for us for the next day as I was with two you g kids and wanted them to get some rest. The gentlemen next to her jumps in and said there wss nothing without even (pretending) looking at their system, I insist and say that they could look for the kids. They seemed to have trouble with our reservation so they gave up. I told them that I needed to talk to a manager, they said there were no managers and that no one can do anything, to which I responded that there must be someone that could do something and that it does not make sense for them to repeat the same think as we are not undestanding each other. She threatns to call security and says I am rude. I say I will go, just give me the vouchers and ger response is “ not giving you the vouchers because you are rude”. I was not rude. It is normal to want to talk to a manager. I even said that the people at the counter were not resoonsible for the long journey and that there was nothing they could have done. But to threten and himiliate someone just because they ask for someone else to talk to ? I understand they are overwhelmed, but you know the quality and calibre of a company in the bad times not the smooth ones. I ended up leaving and paying for my own room and board.

I think it went very well. We flew international and felt safe and well cared for. We were on time both leaving and returning.

Three of four legs of our trip to and from Japan involved delayed flights. Hours and hours of delay. Food poor quality and inedible particularly on the Japan to Toronto segment. Two planes on the Japan to Washington return trip required replacement aircraft to be flown in from somewhere. Boarding in the dark on the field, one passenger fell and was injured. Overall bad experience.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

This was my first time flying Air Canada. My first flight was delayed and then cancelled due to maintenance issues. They kept us informed and put me up in a nice hotel along with 2 food vouchers for my flight the next day. I understand things happen and they took care of the problem very well.I also like the fact that they don't charge for your first checked bag. The food was also hot, fresh and good.

There is not enough room for people over 6 feet in the seats for a flight that long. Crew only came by when it was meal/snake time, in the 11 plus hour flight we did not see anyone walk around, on our flight to Japan we did not know where the call button was to ask for water, on the flight back we finally pushed enough buttons to find the call button

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Lynda was rude and unhelpful. We asked for tea wiht a slice of lemon. She served us Coffee instead. When we spoke to her she made it seem as if we were lying. I asked if she would like to taste it and see - her reply was I don’t need to be rude. After this incident we were treated with subpar service for all beverages and food items after. We’re were purposely left out when they did garbage collection.

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

This flight didn't happen for me because of overbooking.

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

I receive a service for what I pay, so it is fair.

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

Business class seats did not lie flat. There was only powdered milk for your coffee....in Business Class!! Food was good.

Excellent flight and one of the smoothest landing I’ve ever experienced

There isn't much space in-between seats and even water needs to be paid for during the flight.

I paid over $200 for seat selection for these flights and I was still stuck on long international flights in seats that do not recline and do not have the head support cushion. At this point basically all airlines have those for all seats, and this really took me by surprise and made me not ever want to travel on Avianca. The Kayak agent who called me for the seat selection (Donovan) was courteous, but it seems the system for this doesn't work. I was offered seat selection, for the $200+, but without being able to see what I was selecting, with no guarantee where I'd be...and then I still ended up in terrible seats. On my way to, and especially after, a very intense business trip, the seat situation really soured my experience.

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

The connection time is too short to pass through customs and once you do clear customs the connecting flight is in another terminal that is not close.

Boarding, crew and food. Seats are too small Love Avianca

Horrible. I have been trying to speak to a representative to know why I was over charged but I get redirected to AI Vianca everytime with no results. Is there an agency that oversees airline gouging? I will never fly or recommend Avianca to anyone not that you care.
