On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Too many fees (but that seems to apply to all airlines nowadays)

No in flight entertainment, gate employees were very quick and impatient, plane was uncomfortable

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

The Lufthansa part was wonderful. The short connection flight was not.

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

It was a busy flight and all the crew were very helpful and gracious

Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent

Already stated....flights were fine. Late luggage a disappointment and failure my Lufthansa to get my bag delivered in a timely fashion.

Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.

I wish the flight attendant was a little bit kinder
