Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

I needed internet for critical matters and it never worked.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

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

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

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

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.

Food options were ok but the actual meal was terrible. On my way back, they simply said that there was no vegetarian option; somehow they struggled to get one meal and did not give me any breakfast at all which in my opinion was terrible. Never had such an experience in the recent years.

1didnt have wheel chair I ordered wheel chair in my ticket flight

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

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!

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Problems checking in both on the laptop and on the app. No free seating available at check-in as advertised - must pay for EVERY seat between $23 and $75. No way to cancel seat choice. App menus and site menus are not responsive, and some items are impossible to find. Crew and mobile assistance are friendly and helpful.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Very good, i got two seats for myself, and was comfortable with the blanket i got

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

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!
