Pros: "On time"
Cons: "Flight attendants not friendly"

Cons: "Actual flights flying on time. What a mess!"

Cons: "Wonderful"

Cons: "Best option across the pond"

Cons: "Seats hardly recline. Very difficult to sleep in this red eye flight."

Pros: "Some of the crew members talked loudly in the galley all night long. Mostly gossiping and complaining. We had the last seats next to the galley, so it was frustrating to not have quiet and be able to sleep. This was a flight run by Delta for Air France."
Cons: "The food was horrible."

Pros: "The crew was amazing"
Cons: "Don’t change my chosen seat that I paid for as I am entering the plane without my knowledge and acceptance"

Pros: "Lisa @ the Boston Delta check-in counter is AMAZING! She's super helpful and essentially saved our vacation! Her coworkers say she's the best and I couldn't agree more! Delta is very lucky to have someone like Lisa on their team!"

Cons: "With the exception of 1 really nice flight attendant all the others were extremely moody and not helpful. I didn’t see one of them smile through the whole flight like they were just going through the motions. I’ve worked in jobs where you have to deal with the general public but you have a job to do and must smile and do your best to be helpful. I felt intimidated to even ask for anything like I was wasting their time. I love flying Delta and this was my worst experience yet."

Pros: "The staff"
Cons: "Nothing"

Pros: "Crew was very helpful."
Cons: "Food was terrible and check in can be more organized."

Pros: "I booked via Kayak using Virgin Atlantic shared out to Delta. Check was confusing as both airlines used different flight numbers. When I went to check in with Virgin Atlantic they told me to go to Delta. When I went to Delta they told me to go back to Virgin Atlantic. I wound up checking in with Virgin Atlantic. Everyone was very polite but check in was confusing. Everything else was wonderful. Cutomer service was great from beginning to end."

Cons: "Seats are very tight and uncomfortable. The food was horrible. Tasted like a $1 frozen meal that was microwaved til mushy. It was chicken but I couldn't tell you more.

Pros: "Everything that British Airways tried to do to help us when Delta didn't want to take ownership for their screwups!"
Cons: "Not only did we miss our Delta connection but when Delta rebooked us on a British Airways flight they refused to help when British Airways could not access our tickets. they kept saying since it was Virigin Atlantic who we originally booked through that VA woulkd have to fix it, even thought Delta was the actual carrier and the ones that did the rebooking onto the British Airways flight"

Pros: "Everything was just right"

Pros: "On my ticket it clearly indicate that I am entitled to 2 check in baggage. Delta completely refused to honor this. They said am only entitled 1 piece, and therefore I have to pay for the other luggage. I was forced to borough money from someone at the airport just so that I could board the flight."

Cons: "Bad entertainment, almost no new movies. No meal or drinks on international flight, food for purchased was not as advertised."

Pros: "Crew were polite, though they didn't hand pillows and blankets out to everyone. I declined a blanket, since I had one from the first flight, but was never offered a pillow, which I would have accepted. The style of this plane provided a ton of head space, which was really nice."
Cons: "The seats were really uncomfortable for such a long flight. Also, the entertainment system was having trouble for half the flight before they finally fixed it."

Pros: "My seat was actually not too uncomfortable. I had travelled on Iceland air a few years ago and thought the seats were pretty tight and uncomfortable. This was better."
Cons: "Minimal beverages. Must bring your own snacks as they are only for purchase."

Cons: "Landing quite rough."

Pros: "We boarded on time and the plane was clean."

Half way to our destination two of the three bathrooms were no longer functioning."

Cons: "Arrived 10 hours late, lost luggage."

Pros: "The crew was quick and kept us informed; the iPads were a pleasant surprise and a nice addition to a flight"
Cons: "No communication with passengers regarding delayed boarding and absolutely NO announcements to board. Everyone lined up and just waited until they started letting us through, so it didn't even matter what seat you got, it all depended on how close you were to the front of the line. Completely ridiculous. Keflavik Airport was too congested with no consideration given to pedestrian traffic while trying to board an entire plane. Massive jams."

Cons: "Our suitcases got lost"

Pros: "Seats were comfortable with plenty of leg room and the flight was smooth and pleasant."

Pros: "The staff were extremely nice and helpful as I was traveling with bridal dress and the suit of the groom, and, seating in economy class, I was worried about stuffing these items in the overhead compartment. The airline staff helped me store these items in a closet without hesitation; and even checked back in with me upon landing to ensure that I wouldn't forget them while exiting the aircraft."
Cons: "Seat has very little cushion, it didn't take long for my lower back and butt to start hurting. A more comfortable seat would go a long way towards helping one forget they are on a transatlantic flight."

Pros: "For economy class the leg room was actually decent."
Cons: "On every other international flight I have flown on meals and drinks are included. Kind of ridiculous you paid for these things individually on the flight b"

Cons: "The change in Keflavik was unnecessarily confused and lacked clarity."

Cons: "Everything"

Pros: "The aircraft seemed new or renovated and it was fairly clean."

People we wearing their jackets and when I mentioned it to the cabin crew member she said a few other people would have to make a similar comment before she could request turning the temperature up. There was also a glitch in the system so that the reading lights for each seat could only be operated by the seat directly in front. The food was very uninspiring and poorly presented. The tea and coffee were awful!!!!!! The choice of movies,etc was very limited. Thank goodness it was a night flight and not too long!"

Cons: "JustFly did not release my coupon to Lufthansa or Air Canada, and so I was nearly prevented from flying."

Cons: "The ticket was not valid...had to buy a new ticket"

Cons: "I bought my ticket with Air Canadafrom Vancouver to Calgary then connected with Lufthansa from Calgary to London UK. Unknown to me I could not find the flight because it had been changed to an AC reference flight. With a very short time for the connection I did not know where to get my boarding pass as my flight with Lufthansa was nowhere referred to ! Not which gate to go . Why not put it in the ticket that Lufthansa and Air Canada work together and that both flights ref should show !! It would avoid a great deal of anxiety . Only offered 1 round if hot drinks over 9 hours ! Departure delayed by nearly 60 minutes"

Pros: "On time"

Cons: "few movies"

Pros: "Excellent value for Economy flight"

Pros: "Staff all friendly and helpful, both at desk and in plane. Seats were pretty comfortable with sufficient leg room (I am tall), but if you are a wide person (or next to one) it would have been pretty cramped. Neither of my flights (to Newfoundland) were full so we all had a bit of extra space. Food was adequate but could be improved with fruit instead of dessert."

Pros: "The plane took off and landed on time."
Cons: "The food was terrible and the staff were in there own world and not particularly polite. Hand luggage was not managed so the bins were rammed. Some people had 3 pieces of large hand luggage. Food was the worse I have had on any flight. I would rather pay and have something edible. On 2 of my 3 flights the staff were so wrapped up in there own life's, they did not manage to finish the safety checks before taking there seat. Overall a poor experience."

Pros: "None"
Cons: "Better luggage Service"

Pros: "Everything. The plane was immaculate, the seats were comfortable, the food was delicious, the flight crew was friendly and professional.

Pros: "Friendly efficient staff"
Cons: "The plane was a bit dated so the seats were smaller the Luthansa"

Cons: "Flight was delayed multiple times. Was tracking boarding from the Air Canada app as there was nowhere to sit by the departure gate or screens. The app didn't advise that the flight was boarding (unlike other apps such as BA). I missed my flight and they insisted on charging me more than what I paid for the entire ticket just to return home. I got back to London to find that my luggage didn't make the journey. Staff at Air Canada were unfriendly and unprofessional."

Pros: "Staff were friendly"
Cons: "Seats were narrow and sitting in aisle seat you were constantly hit every time cabin crew took trolley up / down aisle. Woke up by cabin crew banging into me."

Pros: "tout était bien - very good"
Cons: "all was good"

Cons: "Would have liked more info as to how to work the gizmos - had to ask how to recline my seat and never did get to grips with the entertainment. The Fast Pass specificaly said it was for disembarkation at London and so I did not realise I could have used it to get through security for ongoing flight"

Pros: "Not much"
Cons: "I was too tall for the seats and the person in front of me was unable to put there seat back, they wanted me to trade with someone else but the. I just would have been a problem for someone else. The steward made me feel as though I was at fault because I should have payed the extra 100 to have emergency exit seating, they tried to get me to sit in the very back row of the plain and sit sideways across the two seats which means I would not be able to sit next to my fiancé. The whole thing was embarrassing and very rude, maybe people of 6'6" should be charged for emergency exit!!"

Pros: "Service in the cabin was great."

Pros: "The plane, which was American-made. Smooth ride in the air, no baggage issues."
Cons: "The crying children in front of me, the hour and a half delay, and the late dinner service. Dinner came at 8:30, after staring at those with special meals eat and finish an hour before everyone else, they should wait with the rest of us. Breakfast was pretty lackluster. Their online app and check in is awful- they should hire new coders and UX designers to increase functionality."

Pros: "Everything went smoothly. Everyone was pleasant and respectful."

Cons: "Was put on plane to France, 5 hour layover. Still waiting for my luggage to arrive. Frustrating in extreme."

Cons: "You"
