Don't buy business class. It"s a relatively short day time flight. and not worth the extra expense. Stick with premium economy.

They are super strict on carry-on size and weight. I have never seen an airline weigh a carry-on before. If you are flying through Germany, make sure to alott yourself extra time to stand in a giant line for a passport check, even though it was already checked when boarding to Germany (not sure what could have changed with it during the flight!). They had given some of our seats away on our connecting flight because we barely made it to the gate in time for departure.

Avoid Frankfurt and O'Hare if you can. Use Amsterdam as your European hub and Minneapolis or Dallas as your hub in middle America.

Airline reviews

I loved the food. The veggie option was delicious. I also appreciate the sense of sustainability with Airline's choice of packaging. Hosteses were super friendly and courtous. I also appreciate that checked luggage was included with the airfare. The entertainment portal could see some improvements. The touch screen responsiveness in Solitaire game was poor and it doesn't seem to be hardware related as other screen functions were just fine. It was hard to move cards between piles and system skipped cards from the deck. Also, there was no option for winnable vs random draw. Sudoku was cumbersome regarding touch screen, too. In addition, the difference between medium and difficult levels in Sudoku was huge. Medium was actually too easy.

This was my return flight and it was 100% different than my out bound. Better seats and great food for sure. As i was disappointed last time but this time they made up for it

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

The flight was very cold, and the seats were rather uncomfortable. The food has been better on our other SAS experiences. Most significantly, the luggage with most of my wife's personal items and clothes didn't make the flight. Hoping for a quick resolution, but no real opportunity to speak with a Human has us concerned.

It was so hot on the plane. No air jets above the seats

Please see my comments for the flight from Chicago to Copenhagen

We were sitting in SAS plus. Super friendly, service that went above and beyond on a Full Flight too! Meals were deliscious and trays were cleared promptly. Generous drinks offered throughout the flight. Would like to suggest better movies on offer to watch.... In all genres and maybe more cooking shows? There was only 1, Nadia's Everyday Baking... Thank you

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

Last minute cancelation, though a substitute flight was found I could not pick my meal or seat. The hotel offered didn't have working air control or shower.

little entertainment choices. Seat/bed too firm an no sleeping mat

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

An international flight on an apron is pretty unusual in my 40 years of traveling. Departure delay. Luggage despite over an hour connection did not make it to the flight. Actually still in Germany. My luggage was not moved until I reached my final destination despite knowing it to be left in Germany upon my arrival in Chicago. The service left me a little off, both going and returning from Europe. Light on in the cabin even during a night flight and lots of traffic no matter what. Maybe passengers want more service? As a frequent traveler i just want to be able to sleep, the food will be better at the destination anyway. So since the cabin crew woke me up I asked for a cocktail, I did not get the best response although sitting in row 20 premium economy. I usually fly premium economy or business and my 2 flight to Europe in 2025 with United both had luggage delays and other minor issues. American flights to Australia, Canada and Europe went smoothly and Premium plus feels very much like business light. Is United Club becoming a waste and Silver/Gold levels another waste??

This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

Could have said yes to a glass of wine 🍷 instead of saying we'll come around in a couple of hours

Inoperable monitor left no entert for 9 hours. Crew was not helpful Food was awful.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

Only drinks included in economy class was water and coffee seat on the 737 were hard as rock. The landing and passport control in Iceland are the worst I have ever seen. 2 hours to clear customs ???? 3 attendants at pass port control out of more than a dozen closed. I” ll never fly to Iceland or transfer through this airport again.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Terrible way of boarding in Reykjavik. Seats comfortable. Meal was good.

Unlike my prior three connections on this latest journey, this flight was fairly good. Only issue was boarding as it was once again one of those Icelandic issues of bunch up, walk in the rain to a bus that then has you run up three flights of stairs to board the plain. I was in Saga class but the bus scramble eliminates any chance you get on first and have to then find a place to squeeze your carry on into an overhead that the people in economy populate so they can grab it on their way out up front. But unlike other Icelandic flights this journey I did find more the of the business class like accommodations then the other air segments. This one found a pillow and blanket waiting for me and I actually received a small cup of sparkling wine and had a bottle of water in place. Service was attentive and the flight departed and arrived on time. Received a menu and had choices of a hot or cold meal. I choose the hot which was cod and it was good. Decent size portion, salad and a choice of dinner rolls. Beverage menu was a selection of wines, beer and soft drinks. Desert was a small Tiramisu. Overall the six hour flight was a good experience for the price point.

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

At least one soda free, felt like I was nickeled to death.

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

We had to be bussed to the plane. And it was raining. Not a pleasant experience.

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

It was good. The seats in economy weren’t bad

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Food was poor quality and the screens for entertainment didn’t work properly

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

Easy, straightforward boarding process. Flight attendant was lovely and attentive, food was delicious - especially dinner, I had the roasted chicken in a mushroom sauce with potatoes - and entertainment selection was top notch. I would fly with BA again.

I love FRA - LCY route. So much better compared to the FRA - LHR route and the price differential is ZERO

It's useless to complain about the space and the back of the seat, making you sitting vertically like a candle. it's your business model. The "food" - there is no food. But I don't care about the food. It's the seating.

Flight take off delayed 30 minutes; arrived 15 minutes late. Had to take bus from terminal to plane, delaying boarding and unloading.

The checkin experience was terrible. Once we got to the counter, it took them 40 minutes to check us in. Nothing complicated. Just 6 boarding passes and two checked bags.

Great crew! Average flight. T5 at Heathrow is not such as nice experience compared to other major International airports.

Our stroller got lost when flying from San Diego to Frankfurt and our luggage got lost when flying back from Frankfurt to San Diego, We had to rent a stroller during our 4 week stay and had to no stroller during our trip back to the US. Our suitcase is also still missing. We sent and email 3 weeks ago and are still waiting for somebody to get back to us.

They ran out of headphones so my 3rd daughter couldn’t use the onboard TV the entire flight. They also rain out of food, so my 1st daughter didn’t get to choose her entrees or snack (chicken or cheese) because by the time they got to the last row they only had chicken left. Luckily she is not a vegetarian.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well
