Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost.

The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact).

Okay 5.3

It was relatively inexpensive. I didn't mind the food/

This flight was operated by BA. Seats were incredibly uncomfortable. When the guy in front of me reclined his head was practically in my lap. TV's were crappy and the in-flight selection was mediocre. In flights announcements were very loud through headphones.

Okay 5.3

The configuration of the seats are really awkward. Seems very interesting at a glance, but not so nice when you have to sit in it for 10 hours. The business class seats are very narrow. I'm pretty petite so it was okay for me, but I think an average or bigger than average person would have a hard time turning at all while the seat is in lie flat position. I had a window seat which gives you more privacy as long as you have the divider up between you and the passenger next to you. You are really arm length away from each other though. And! You can't have the divider down the entire time because they serve your meals by passing it over to you across your neighbor through the divider. The divider is also required to be down during taxi, take off and landing. So, I'd imagine it to be very awkward if you're sitting next to a total stranger. You also have to straddle over someone's legs if you want to get out of your seat to the bathroom if you have window seats.

Seat and foot room was extremely cramped , and I'm 5"4 115 lbs, seat was horribly stiff and uncomfortable , the entertainment system broke throughout the plane an hour into flight, you never saw crew in less they were serving food, it was very very load , it was a pretty awful experience and I'm not looking forward to the flight home at all

The crew was very attentive

As much as the flight was truly very good and the crew very friendly and helpful as much as the equipment (airplane, seats, entertainment) really shabby and certainly not worth the the 2500,00 $ I paid for a better seat. I could of flown with Air transat and get better than I got with Air Canada. I feel it was rip off. Quality - price not there . Please give your crew a better uniform. The ones they wear now is very sad and oldish looking. If I think this and am 67 years old, imagine what the younger generation thinks.

I felt that they were very thoughtful about the fact that it was a long flight. We got two small meals, which was perfect, and even a little gift bag with a sleep mask and toothbrush and such in it. These were just a couple of the many nice touches included in the flight.

Very small quibble: the screen resolution, or maybe the contrast, of the personal video players was not so great. This was fine in most cases, but it meant I could not watch videos that had subtitles. Not a big deal but possibly worth fixing. Thanks

Nice Airbus plane. Due to thunderstorm in Dallas, pilot not able to leave DAL to come to fly the plane in LAX on time. We delayed around 45 minutes. Otherwise, crews were professional and efficient. Excellent movies choices.

Boarding announcement in SFO was bad. No one can hear what the agent announced. Random sequence of boarding with confusion. In LAX, we supposed to go to a different terminal by a bus. There is no guidance out of gate to assist passengers that transfer to get on the right gate on the right bus. In AUS, there is not any announcement for luggage belt. An announcement would be helpful to new arrivals to this airport.

This flight was as good as my first with them. Absolutely wonderful service. I might be painting the experience a little extra rosy because this was my first business-class flight, but I feel like I never want to fly coach again.

Boarding was a real hassle. I think they called for Saga-class passengers to board early, but there was no way for me to get to the gate through the ocean of people. I was on the other side of a glass divider, and it was shoulder-to-shoulder crowds the entire way to the plane. Oddly, I had no access to the free Wi-Fi on this flight.

When I booked this flight last March the booking info said 1 free bag. When we got to the airport we were told that we had to pay $94 Can per bag because we had Economy Light class. We had the same issue returning but the cost was $55 US. On top of that Iceland Air changed planes and bumped us from row 10 to 41 - the last row. Bizarrely there is no customer service desk at the Reykjavik Airport - they just give you a little card with the website for customer service. I don't understand how any airline does this!

Arrived in Oslo 16:30 Oct 9, now 18:42 Oct 10 still no luggage, no help, no cooperation, no compensation, no vacation. You can’t leave to go anywhere else, if you have to be somewhere to receive the luggage, even if you go buy new clothes.

It sucks to have your vacation ruined by lack of ability to deliver my luggage 35 kilometers from the airport. terrible customer service from Icelandair, SAS, and Gardemoen Airport. All fingers pointing other directions.

It appears that Air Canada is doing the correct thing for passengers who have reserved their seats in advance....after many years of not applying their written policy of making them board after business class/disabled passengers/passengers with young children, they have created Zone 2 boarding which permits passengers with reserved seating to board immediately after them, therefore guaranteeing them overhead bin space. As we all know, a lot of passengers board with much more than one carry-on, which is a plague when boarding.

767 300 was clean and staff wasn’t fussy.

Staff seemed disinterested in passengers and boarding was extremely disorganized. Flight was also delayed because of a missing passenger. Not sure how that happens.

This flight was as good as my first with them. Absolutely wonderful service. I might be painting the experience a little extra rosy because this was my first business-class flight, but I feel like I never want to fly coach again.

Boarding was a real hassle. I think they called for Saga-class passengers to board early, but there was no way for me to get to the gate through the ocean of people. I was on the other side of a glass divider, and it was shoulder-to-shoulder crowds the entire way to the plane. Oddly, I had no access to the free Wi-Fi on this flight.

First experience flying business class -- and Aer Lingus has it down to a science! Great food (maybe too much actually!), friendly attendants, great service -- and the most wonderful pods that allow you to lay out flat for a snooze, complete with duvets and pillows.

Crew was professional and polite. Food was tasty. Good entertainment available.

Unfortunately, some technical issues prevented us from taking off on time, and we had about an 1 hour and 15 minute delay.

Supposed to leave Boston at 9:30 pm, instead 1:30 am. It was said they knew this the day before and sent emails to passengers. No one who I spoke to, including myself, got one. Aer Lingus hired another carrier to do this flight—plane, crew —no Aer Lingus personnel. Everyone was nice, but. Had made arrangement for early morning checkin. Got to the hotel SO late that they waved a fee and had our room ready. Was going to sightsee the first afternoon—basically lost a day of seeing Dublin.

3 hours late, no electronic notification. Figured it out on my own, then missed my connection to Oslo. Got transferred to SAS for the last part to Oslo, without checked bag. Arrived in Oslo 16:30 Oct 9, now 18:42 Oct 10 still no luggage, no help, no cooperation, no compensation, no vacation. You can’t leave to go anywhere else, if you have to be somewhere to receive the luggage, even if you go buy new clothes.

It sucks to have your vacation ruined by lack of ability to deliver my luggage 35 kilometers from the airport. terrible customer service from Icelandair, SAS, and Gardemoen Airport. All fingers pointing other directions.

My wife’s screen did not work. The pitch between the seats was too narrow for a transatlantic flight. Older plane that needed to be cleaned and updated.

Not a thing

The fact I didn't even make it to my destination. Not one person working for Air Canada gave me the impression they knew what was going on. They certainly didn't apologize for ruining my vacation and they did not try to do a single thing to help us make our flight or make the disappointment of missing it any better.

Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost.

The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact).

Good flight, really good new A380 aircraft, smooth nearly all the way, usual small seating space as on All airlines

Routine airline food.

It was relatively inexpensive. I didn't mind the food/

This flight was operated by BA. Seats were incredibly uncomfortable. When the guy in front of me reclined his head was practically in my lap. TV's were crappy and the in-flight selection was mediocre. In flights announcements were very loud through headphones.

Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
