3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Other than a delay that had nothing to do with the staff, it was a very pleasant experience.

3 Flights were late, 1 on time. When you have connections you have to run thru the airport because there is not much time. When asked the flight attendant if they could let us out first because we were 30 minutes late she said it's a small airport, don't worry. That seemed to be the standard line. Other airlines are much more helpful. Our special meals were on our flight going from Boston to Copenhagen, They did not have them for the return even though we had put in for it.

SAS is the representation of the Scandinavian minimalism, which I like. I wished they had a more relaxed policy on free water distribution beyond one bottle (500 ml) per person and two drinks, including water, per overseas flight.

Bathrooms weren’t too clean. Onboard entertainment was light. Other than that everything was great. Food, service, comfort and crew. Although it was hard to understand the crew announcements.

Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

TERRIBLE! Staff was unfriendly, rude, and demeaning. One flight attendant touched me to grab the complimentary blanket off my neck because I couldn't take it home, while a bunch of other people took theirs home. I have never been so ill treated. I am not happy at all. And flight was delayed, no information until short notice for everything. Lost an entire day at my destination. I expect a full refund for that experience. Never will fly with them EVER again

My return flight has been changed to JFK from EWR without any notice or reason

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

I couldn’t make it to the airport for my original flight due to bad weather; roads were shut down, buses and trains were closed. Since the plane wasn’t cancelled, I still had to pay $720 to change my ticket.

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Food was terrible Not many options Stewards dont care Delay

The ride was good but no food ot entertainment hence, it was just over an hour flight.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

My experience with Icelandair was just ok, nothing special. Requested wheelchair service for my wife and none was offered at checking in Baltimore or available for her upon arrival at Gatwick airport in London.

Decent service - nice seats. Crew were not overly attentive but can’t complain overall for the money

Very nice flight, easy connections in Keflavík, and friendly crew.

I will never fly this airline again. Checking in was poor , we had to go back to the check in counter at Raleigh - Durham international airport three times because they didn’t issue my boarding pass but rather duplicated my husband’s twice which caused a big headache at the passport control at the airport which triggered security alert and wouldn’t let us pass through we we had to wait for long time to be able to explain and clear everything after talking to the supervisor.. No food on the plane , not even crackers. No food was offered to buy ether . No ear phone was provided . Very little time to make from one plane to another and nobody to assist with smooth transition. Flight itself , we felt safe so thank you to the pilots . But customer service was terrible . We spent $ 2500 on 2 tickets, so I cannot say that service was consistent with the price .

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

Food was horrible. This wasn’t business class. No leg space, can’t sleep in row position, huge delay

I liked how easy my transfers between flights in Keflavik were. I would have appreciated more food options in Keflavik.

The plane was flaming hot! Could not breathe. Everyone coughing from heat. Awful.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

Not much! This was my first flight with Iceland air and unfortunately it wasn’t what I have expected. My luggage is lost nothing as of yet where it was left. Not a good service at all!!

United delayed the flight to assist customers to make the connection. The Ohara customs area was overwhelm which created an issue for customers trying to make the Little Rock connection. The delayed allow several customers to make the final flight into Little Rock.

Missed our flight to London and we were put on coach seats to Munich.

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

They canceled our flight last minute and we had to get another flight with twice the cost

Dinner was excellent - beef stew, the eggs for breakfast were only ok. It was soooo nice that there were so many options for movies and games.

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.
