Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

My business class seat was inoperable and unable to recline for 10 hour flight.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was terrible. sat on airplane 2 hours then flight was canceled. made to pick up bags and go through Panama immagration to rebook another flight. worst experice ever at a airport.

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

Lounges are packed and very poor, food is really bad, for business class in an airline is well below expectations

First time flying with UA and it was a great experience. Thank you

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

It as confusing with the connections and I almost missed my next flight because of the first delay with the first flight. United could have helped passengers go through immigration quicker rather than waiting with everyone else. The flight attendants were super friendly and lovely. The vegetarian food was awful- I did not finish. I would suggest they just do pasta next time

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

They were fast and I like how they used to entertainment system to play video about the safety.

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

Flight didn’t happen because both my connections were lost and Toronto wouldn’t let me board. I was checked in to all 3 flights at the check-in fest in Dublin.

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

Flight was delayed for 5hours. Food vouchers just aren’t good enough

Flight was early. That’s the only positive I can share. I paid for wifi on the flight and it didn’t allow me to use any streaming services so it was a waste of $20. West Jet also lost my ski equipment on my way to a ski vacation. They told me it would be delivered to the hotel as soon as it arrived at the airport. It was never delivered. I had to pick it up at the airport on my way home. I am completely disgusted with my experience on west jet

No kiosk to help pre boarding unlike other airlines, still lost the luggage despite its own crew/TSA or security tagging it, poor handling of lost luggage and possibly compensation is likely poor too.

Everything was great until we had to get our bags. The bags came out in several different batches over 90 minutes after we landed maybe more we got our bags. So much for the old West Jet where they promised bags in 20 minutes. I Next time I will pack lighter and go with a carry-on.

The flight was full and good as could be expected. We arrived early which is always a good thing.

Not sure what happened, but for some reason we had to sit on the plane for an extra 10 minutes once we arrived in Abbotsford. Obviously, it was an engine issue.

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Got home at 3am after deboarding the plane. No compensation offered by American

Flights on time w/o delays. However, my baggage was damaged. Ground crew, throws baggage from plane to the baggage carrier, carelessly.

AA was a very good experience. The employees are wonderful

Business class was very good, one of my best flights

American flight was diverted and delayed but app didn’t show that information so I wasn’t able to change my connection until the last min.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

Checked bag was severely damaged. Whole corner was riped off including 1 of 4 wheels gone. Insulation exposed. This made it not possible to fly with on my next-day American Airlines flight.

Air condition was not working for long both after boarding and also after landing ; unbearably hot and suffocating

Human interaction. Thought there would be more service-even a smile would have been nice.

I was tired enough to fall asleep soon after takeoff and slept until "we are starting our descent to Toronto" announcement. That's not bad at all.

It was great to have a vegetarian meal option, but departure was delayed because they had oversold the flight. Air Canada, you’re in charge of how many tickets are sold: don’t oversell!

The lead flight attendent was outstanding. We were delayed waiting for a connection and she kept us up-to-date with a great sense of humor. She also made sure a passenger in the back of the plane was sble to get out first to make a connection. She needs to be recognized by your company! She is awesome!

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

Very bed experience never want to travel air canada anymore

Was not sent a link to check in online. Tried to check in online using website. Site didn’t work. Called support line, was told it often didn’t work. Went to counter at airport to check bags and get boarding passes. Had to stand in a lineup. They were unable to tell me how much to pay. Had to take a paper to another counter, took a long time to be told what I owed. I fondly remember the days of checking in online, getting my boarding pass digitally, paying for my luggage on line, scanning my passport at the airport to get my luggage tags, and putting my luggage on the conveyor. Easy peasy. Air Canada has really taken a step back in time, and made what was an easy check in experience to one that seemed unduly long and frustrating.

Really out of Air Canada's control due to long delay because of mechanical issues. While doing their best, disappointed by their assumption that all passengers have smart phones. Should have communicated food voucher availability at gate area. Late arrival cost me an extra $51 because public transit was not available, Otherwise, feel Air Canada did their best dealing with their challenges. Will likely continue using them in the future.

They canceled my flight, I had to rent a car, drive 14 hours. They tell to go on line for a refund, but only offer $24 for a $210 flight and you can’t get hold of anybody by phone and no help from staff at the airport.

I wish to travel with Air Canada for my next trip

They were very attentive, polite, professional and great customer service skills.
