Get to the airport early so you’re relaxed. Con yourself into believing it’s bedtime and try to sleep so that you can keep going all day when you get there. If you can afford more comfy seats it might be worth it - though I always have the cheap ones so I can’t say for sure. Try very hard not to. sit in the middle. I’m small and the guy next to me played games all night and didn’t care that he continually ( with every move) jabbed me with his arm. This was my first flight with Cheap Flights and it was far less convenient than other times I’ve flown overseas.

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Excellent experience with business class area. Staff was attentive and food was amazing. Only one bathroom for business class which was logistically difficult for the staff while preparing meals. Need to offer fluids with meals. I did not get enough water to drink. But overall I rate it 5 star.

On time, great food, good drink selection! Only down was alcohol-free lounge. Lufthansa had a much better offering!

Be honest of what you sell: This was sold as Business Class on all three legs, while the JetBlue plane didn't even have business class seats, and wanted $164 for extra legroom seats.

Seat assignments for family traveling with 2 children. Loud crowd during sleep time

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

delayed to take off from detroit by 3 hours lost baggage in istanbul and now in venice without baggage

Seats were very tight with poor legroom - and I am average height. During the 12 hour flight, tiny paper cups of drinks we're only offered during the super and breakfast services, with the crew nowhere to be seen in between. One of the bathrooms was out of order, leading to long lines waiting to use the remaining two available to the economy class passengers.

short flight but we still got a very nice lunch and the crew did an excellent job in taking care of us

For that price on Business class, I expected to have the pod seats. These were configured as 2/3/2 and my seat mate talked half the flight with a friend across the isle, loudly. Very uncouth.

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

On time, reasonably comfortable for economy, decent food. All in all a very good experience.

Every flight got canceled or delayed. Customer service was awful.

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

No free Wi-Fi. I have SkyMiles but not a high status, having an account has been enough for Wi-Fi on other flights, but this one was going to charge me to use it. Also turbulence was really bad toward the end, but I didn't count this in my ratings since I know Delta cannot control the weather - it's 2026 and lack of WiFi alone is enough for a poor rating.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Crew members were excellent. The seat wasn’t the best as well as a food options.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

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.

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

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

Pleasant, attentive flight attendants, but they’ve got to upgrade their seats to be a true “business class” carrier.

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

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.

I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

Iceland Air severely damaged a checked bag. Additionally, the gate agent caused issues for many passengers who had standard-sized onboard bags that would have passed inspection by any other airline.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

They messed up my seat so I didn’t get the one I paid for

Put me on standby; flight was late; missed my connecting flight; disaster

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.

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.

In my first flight with Air Canada we sat in the plane for 4:00pm to 6:30pm. Finally we were asked to get off the plane and we were told the flight was cancelled after 7:00pm There was o clear explanation of what was the problem. I was booked without my permission on a Delta Flight at 7:30pm that was leaving at 8:00pm and I still had to go get my luggage(my final destination was Rome with one stop in Toronto. The luggage claim for Canada was closed so had to return to finally get it on the luggage belt.. Of course I missed the Delta flight and all the next day flights were booked. I also lost what I paid for my stay in Rome because I did nt cancel in time. A complete nightmare.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.
