I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

The woman in seat 1A was allowed to bring a dachshund dog onboard. It smelled terrible and the odor wafted throughout the first class cabin. This was clearly not a service dog and should be prohibited. I paid for the highest class of service, and this was a disservice. Why is Delta allowing this? I may reconsider my future flight choices.

The plane was very warm upon entering. This was a bigger problem as the weather was cold so people were dressed accordingly.

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

Crew was very helpful with mobility assistance from end to end. Very caring.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Food TERRIBLE! In First Class- so bad - why was it so much better 20-30 years ago? Comfort-awful-would rather have the old, plush First Class seats than the new hard - too short seats in the new pods -would advise avoiding Delta for any International Flights.

The flight was delayed so the people from a late connecting flight was able to still make the connection.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Ridiculously slow disorganized boarding, ended up 35 min late and people missed connections

The Cree was BEYOND AMAZING. They were, by far, THE BEST CREW I had the pleasure of flying with. They catered to my every need, beyond friendly, and upheld the highest level of professionalism that is of Lufthansa Airlines.

Really solid flight! The in-flight entertainment screens are not very touch-responsive in the way that of other airlines’ are, which was my only issue. But otherwise we had good food and drink offerings and the flight attendants were very welcoming.

The incoming flight was delayed so boarding didn’t happen on time. Upon landing in Munich, we couldn't pull up to a gate so we had to disembark on the tarmac and be bussed to the main terminal. This caused a mad rush for me and others who were making connecting flights to get to our new gates, and my bag didn’t get over to the new plane in time.

The Frankfurt airport is just not that easy to get around. Having to get from one end of the airport to the other when it was not well marked was a challenge. The flight itself was fine. I would fly with United again.

Lufthansa and United Airlines messed up with our reservation and they canceled our flight to Los Angeles. We ended up stuck in Frankfurt with two little kids. They sent us to San Francisco, but their flight was full and they wanted us to sit separated (even our 3-year-old was supposed to sit separated from me or my husband!!! Isn't it illegal???). Then the flight from San Francisco was delayed and we had two little sleepy kids, we were also told we needed to pick up our luggages. It was just horrible. I paid for a direct flight from Frankfurt to LAX and ended up going through hell. I am very upset and going to submit a complaint.

Crew was good. Check-in and boarding was terrible. Family wasn’t seated together. Online check-in wasn’t available.

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

Packed commercial flight was as comfortable as can be expected

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

Flight attendants on American Airlines are rude very harsh with their time of voice. Nearly identical experience as spirit airlines. However, from Spirit Airlines, you expect this level of mediocre service. You do not expect this from the big three..

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

They give you slippers, which I loved. I wish they gave us more treats and snacks for the long flight.

WiFi wasn’t working on the flight, several delays and gate changes, ended up taking off 3 hrs later

Overall, I had a great flight on American Airlines. The only compliant that I have is that my gate changed 30 minutes before boarding the flight. This was annoying because I had a connection in Charlotte and it's a very big airport.

Unfriendly gate staff and significant delay once we were on the plane.

Happy and nice crew and the atmosphere is very easy and calm. I got a wonderful travel with UA this time

I wouldn't recommend Lufthansa otherwise. We took this flight only because our flight to Kittilä got cancelled and Lufthansa offered a replacement which would have been two days later, with a night in Frankfurt and another in Munich. We refused the replacement but the staff at the airport entered in the system claiming that we accepted the replacement.. We didn't get the full refund because of this.

Seat cushioning, and having at least 1 checked bag free, I dont understand why international flight would not include a checked bag.

If I book through Lufthansa, I expect to fly on Lufthansa, not discover. Food was bad, plane was delayed. Will not be flying Lufthansa again.

Food service was good. Aircraft was old and needed upgrade such as seats. Flight was delayed about 1 hour.

So poor I will endeavour to never fly with them again. Booked flight direct with Lufthansa, LHR to Leipzig, with stop in Frankfurt. Transfer in Frankfurt, via app and website was a '9min walk'...it, quite simply is not - it was a complete terminal change, with passport control & 2nd security check. No guidance provided by gate staff. Missed connection (despite agents at passport control granting line bypass and running for 750m). No assistance from gate agents at missed flight (along with approximately 15 other passengers that didn't make connection. Lufthansa Service Centre staff helpful - their manager was not, stated it was our fault for not leaving enough time to make transfer, revoked compensation....err, how are we supposed to know about construction, new security procedures, late gate changes??? Really??? We went were airline sent us, at pace, they messed up (twice on both legs of journey). Will avoid at all costs in future.

I arrived late in Frankfurt and I had to catch my flight to Vienna and I was running late because when I was landing the flight to Vienna was boarding. I had to go through immigration and then I had to wait in a long line to take a bus to a terminal where my flight to Vienna was taking off. However, I truly didn't think I would make it. I was literally running through the whole airport and when I stopped to ask at one of the Austrian Airlines gates they were rude because they didn't have the time to support me.

The real bathroom smelled horrible and it smelled in the real of the plane..

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?
