The flights are constantly late anymore, and they won't even give you a glass of water on the plane. For years, they were able to do a service on this flight from Atlanta to Knoxville and Knoxville Atlanta now they say it's too short of a flight. You can't even get a quick drink of water.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

The flight was cancelled, so why are you asking me how the flight was?

Fortunately the departure was delayed as I had a tight connection and the incoming flight was delayed. The departure delay helped me to make my connection. Thankfully, my luggage also could be transferred in the same time. The aircraft had to be changed and the power outlet in my seat didn’t work. Again luckily as the flight was not full, I could move to a different seat where the power outlet was working.

Boarding was by group and we had to take the bus. There were no elevators so had to walk down the stairs. It would help to have escalators or elevators. Note I had a special needs child and the gate crew was rushing us in. The bus was full but we were packed with no seats to sit.

The food from Delhi to Frankfurt went bad or something cause I got sick after I ate the meal and felt ill the rest of my travel back to NY

Everything was on time, even though the layover in Frankfurt was 22hrs

Very friendly, service oriented and responsive crew. Very pleased with th service!

The entertainment is pretty boring. There are no new movies or TV shows from February. The food is just ok on the Atlanta to Frankfurt leg, but better on the Fra to Bengaluru leg.

Flight LH760 from Germany to New Delhi, the food was excellent, the crew was fantastic, the seats in economy are usually tight these days, so I can say that the seats were Ok, the entertainment was OK because for some reason the sound is not very clear, overall I enjoyed this flight, compared to the flight (UA 962) I took with united from San Francisco to Frankfurt in this trip, that flight was horrible. Thank you Lufthansa.

The crew was exceptionally polite and caring. The plane was comfortable. Great experience. Will fly more on Air India because of this experience.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.
