The boarding was good but the line for check-in is pushed off to the side because of the recent construction. It’s fine but cramped as people jostle to get checked in. Also, we weren’t able to use our online check in and printed boarding pass so we had to basically check in twice.

If you don't have checked luggage, no need to be in a rush to line up. There will be a spot for your little carry-on rollie bag, so relax until the line is down to board the plane.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Good experience and the flight landed early. There was no food I had or entertainment.

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

Smallest leg room I've ever had on a plane.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

After arriving in Istanbul, the transit information on the electronic board showed a tight departure time, and the gate changed in the middle, making it difficult to make it on time.

Typically good service onboard but baggage delay in airport was significant

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

They oversold the tickets by one which was my ticket so I didn’t have a ticket till last second

Not good. I was supposed to be in Mint but got in economy class

Service was slow and checked bag was off last evening when flying business

Turkish Airline canceled our tickets in the very last minute, with our luggage and everything else, all prepared and good to go. It’s clear that they sold the tickets for better money to someone else. Bad, Bad, Bad business!!!

Awful seating. Bad food. Staff only have one bottle of water and no cans.

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.

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

Delays at check-in, seemed like they were short ground staff at the time and some passengers needed extra processing.

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.

Food - Non-Existent. You pay for everything. It is strictly Pay-to-Play!

The Experience Was Torture Spend a few extra dollars and avoid Icelandair at all costs. There is absolutely no refreshments, no food, no drinks. Only water, coffee, tea are free and at only half a tiny cup. Entertainment is limited selection of films, shows and mostly outdated. The seats are smaller than usual, with no cushion, no pillows, no blankets. First time in my life have I witness an airline asking for donations in spare change for a charity. With all the money Icelandair saves by starving the passenger, they can afford to give this charity on their own.

Again, we paid $ 328.00 for specific seats are were assigned those seats.

Never again. Terrible hospitality and human decency for an international flight. No food, no snacks, no beverages, blankets, pillows, limited entertainment. Tiny seats without any cushion and some do not even recline. I was shocked that they did not charge for seat belts. Never in my life have I witness asking for "spare change" for charity before landing on both legs of the flight. Icelandair can contribute on their own to said, so called, children's charity with the money saved from providing 3 centimeters of tea and water to hungry and dehydrated passengers.

Having been prepared for paying for everything on board other than water, coffee and tea the service was OK. Food and drink is expensive but the food was OK if limited in scope. Plane was clean and obviously well serviced. After complaining about having to walk in wind and rain to a get a bus to the airport the same thing happened at Portland. I’m sure you could get a terminal gate flight, complimentary food and drink for not much more money without traipsing through rain and slush in Reykjavik. Not bad but not great.

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

Excellent service; they helped me reschedule so I can fly in an earlier flight

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

Crew was professional and great, flight was clean. However food was pathetic. I ordered a Hindu meal assuming no meat but they served chicken. Need to be very specific- Hindu meal should be categorize as Vegetarian - no meat or egg. Or it should be specific that we are serving meat.

Late flight Delays Poor service Poor staff Worst airline ever

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

The issue was not with BA it was with the link yoiu sent fopr booking the flight

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Getting the boarding passes between the BA and AA apps was very clunky.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.
