Very good seat and service. No complaints about the food. Take off delayed due to airport traffic

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

I am a die hard Delta flyer, but they missed it on this flight. It was on their very dated 717-200 aircraft, which I knew when I booked it so I knew it wouldn’t have seatback screens. However, the internet was awful and it wouldn’t even send texts a lot of the time, much less even connect to the delta app. It was also very hot while in the air, which never happens. What was even more disappointing is that the crew only gave me cheezits and a beverage, even though I was in Delta Comfort. The main cabin fare gets these items. I didn’t get any kind of improved snacks and that was unacceptable. The crew wasn’t very visible at all either. If this was my first delta flight, it would be my last. I am just going to assume it was a one-off flight.

flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

We departed and landed early which was a nice surprise. The boarding process was slow.

bulkhead seat had very little legroom - even in bsiness class.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

The best airline I have ever travel , really good customer service, attention and service !!

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

I was forcefully re-routed to another destination and was delayed a total of 8hours. I have still not received my bags, no one is taking responsibility. The agents at the airport lied to me that I will get to my destination same time as my previous flight where I was forcefully re-routed from.

Everything ok, but it was a lot of turbulence during the flight.

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

There was a terrible delay upon arrival in Barcelona. The plane had to park a great distance from the terminal, and only one bus was available to make the ~15 minutes each way trip, meaning it was ~ 45 minutes after we landed that I finally entered the terminal.

Arrived at our connection to find out all 4 of our seats were moved in different parts of the aircraft. Traveling with two small children, this was not going to work. We spoke with the gate attendant and she was not helpful and downright rude. They could only “accommodate” having 2 seats together and this was an international flight. We will not be traveling with air Canada again unless there are absolutely no other options.

Checked bag- one should be free for overseas flights. Seats were extremely uncomfortable. Will probably not fly Canada Air again.

Our flight was cancelled half hour before boarding. We then had to spend hours on the phone to get a much longer re-route through Munich with an extra 10 hours of trip time. It caused us to miss a full day of long awaited vacation. We are extremely disappointed.

Long fight… The staff is very friendly and the meal provided was nice.

Terribly inconvenient to not have WiFi for the entire 8hr flight. Sitting in business class, we were surprised the bread was served cold, not room temp, cold. They used to be served so that they seemed freshly baked. Same can be said for the squashes croissant at breakfast. Both were squashed flat. There was no champagne on the flight. And, bring back beverage service prior to take off!!!! Our departure was delayed for over 30 minutes so no beverages really stood out as something missing. Crew, seats, entertainment choices, all excellent!

It started well but flight was cancelled and they created a nightmare rebooking. It is two days later and we still haven’t reached our destination. I am in Amsterdam waiting on transfer desk to open (later than other airlines) to hopefully get a boarding pass. Once that problem is solved we will just pray this flight isn’t cancelled too.

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

We were charged for luggage, and our ticket was with Lufthansa and was supposed to include luggage fees. So our experience was a bit bad. Also, the flight was about 45 minutes late arriving.

The real bathroom smelled horrible and it smelled in the real of the plane..

The connection between my income flight and the outgoing flight was slightly late and they would not hold the next flight for 7 minutes. The next flight was 4 hours later and we were issued a stand by ticket. So we had to wait to find out if we would even be on that flight. After boarding that flight was delayed for 40 minutes because there wasn’t a ground crew to load the luggage. The airline is not living up to it reputation.

This flight space was way better than our international flight. Efficient boarding and comfortable

Shorter flight but no food or entertainment. Flight was packed and no room to store carry on baggage.

We paid Lufthansa for reserved seats months before this flight. Apparently this was not forwarded to ticketing as the clerk at check-in gave us seats at the very back of the plane next to restrooms and storage. Needless to say, we didn’t sleep at all on our overseas flight. We sincerely hope that our accommodations are better when we return to the US on October 11th.

We connected to this flight very late, in fact at departure time. We were last to board. The crew was very empathetic and welcoming. The plane was impeccable. We flew economy, so it was a bit cramped. We were served a snack that was more than expected these days. All in all a good experience.

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

As I said Al & AJ were absolutely the best and wow they should be recognized for their amazing service!

Flight was on time. Boarding process was tedious. Not much overhead cabin space. Seats very close (front to back). Uneventful trip just the same.

The crew will not help you with the overhead bin even if you are business class. If they do, there's always the sentence " we are not supposed to lift anything".... To charge for seat assignment in business class is nothing short of money grabbing/ ripoff. The ground service in London is better than Vancouver, which was atrocious.

Quick boarding process, slight delays on the tarmac prior to takeoff and a late arrival due to an emergency on the landing runway. Not the fault of the airline at all! Cabin crew was very friendly and the Captain kept the passengers well informed about what was going on

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

Excessive delay without proper communication. Mediocre for a BA flight.

Another old plane. This time they changed gates at the last minute and when people arrived boarding was delayed

Still unhappy cancel fight rebooking half of what I paid fore! Terrible!!!!

The food was awful and little, on the plane there was not space to even move in the aisles, the seats were super close to each other, no confortable at all!
