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.

We left our child’s tablet on our seat 12 B on the plane and we can’t get a hold of anyone to try to get help locating the tablet.

My flight was cancelled after a 7 hour delay. I am awaiting a refund.

Food was low quality as well as quantity; I ordered vegetarian. We waited 35 MINUTES for the first bag to arrive after landing.

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

Our flight was delayed by 2-hrs but I understand it was beyond the scope of the crew members

I am quite satisfied. The flight was on time and landed early. Staff was friendly.

I could change to business before flight and everything was perfect except for entertainment which was none.

Needed more info on connecting flight. Late flight made very short connection. Lost luggage that we still do not have!

Seats comfortable on economy plus and attendants very helpful. Food was ok. Bathrooms needed servicing.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

The whole flight was coughing and farting all the way. It was impossible to breathe. If people are traveling sick they should either not be allowed to fly or made wear masks

Non stop flight from Barcelona to Rome, arriving on time.

3 hr flight from Barcelona to Gran Canaria. Ŵent according to plan No issues with staff oŕ flight. Many people includiñg us could not get luggage self checķ in termìnals to work. Had to wait in check in line.

The communication about the delay could have been better before and during the flight. Also, this online form could have less bugs. It is almost impossible to type in this window.

We got to the airport 2 hours before the flight. We waited in a line to check our bags onto the flight for an hour, even despite having checked in online, as there weren't enough self check terminals allocated to Vueling (yet loads of empty BA ones right next to them). There also weren't enough staff, making them stressed and rude. We had to try and rush through security to get to our gate, which they announced as gate 35 at first and then changed it after ten minutes with no announcement to anyone in the airport that it had changed. So we then had to rush to the correct gate to arrive just as boarding started. It was a thoroughly stressful process and one travelling couple almost missed boarding because of it. The flight boarding and the flight itself werre fine, the staff were polite, but I was dehydrated due to the airport and had to buy a bottle of water as they didn't offer free drinks.

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

You have couple of KG's grace on checked luggage

Last time bucking this company if I would know I wouldn’t do it, they made me lose my flight

The baggage policy is pathetic. We paid for our carry-on bags online. Said if we don't remove the wheels of our carry-ons it's not considered a carry-on. We all measured our bags according to the website beforehand. We were not refunded for our bags and were obligated to buy it as checked in bags for over $70 online or $90 over the counter. First and last time I travel with this airline.

Because the scale includes two terminals, we almost lost our flights. That data was not referrenced to us. The check-in process was a pain too.

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.

Boston Logan is a crummy airport - signage is terrible or lacking in areas. Boarding seemed to be a free for all and with all the different airlines speaking, you couldn't tell who was supposed to be where and when. Plain and simple, airlines should board from the back of the plane to the front. Also someone was sitting in my seat. By the time that was figured out, I had to place my overhead behind me which made de-planing more difficult. Logan is not Lufthansa's fault so that is not on them, Boarding is on them! Still, overall it was a Good Experience flying with Lufthansa. This is not my first flight with them...

A better organized line of passengers at the boarding gate. Quite disorganized, with multiple queues of economy class passengers

AMS FCO in their full flat business. Amazing sear and food experience.

It was a short haul trip, so food and entertainment weren’t a big issue

The plane seemed very dated. The entertainment was very limited. There was a school group on our flight and the crew seemed bothered by them. They were not overly friendly or welcoming.

Ok, but no entertainment. Left late, but made up most of the time.

May be it is not an ITA issue, but the bags took long time to go out.

Good. But there food was poor quality and 95% of movies didn't have English subtitles

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

Service from staff was poor, food choices were limited. Air plane was not clean or hygienic and seemed like not cleaned for days. Seats were uncomfortable.

service from stAff was barely there , food choices were limited. AirPlane was not clean and seemed like it was not cleaned for days.. Seats were very uncomfortable.
