Delayed getting out for no good reason. Tight connect lead to a missing bag in Hamburg. Waited two hours at the airport to get the bag from the next flight.

Delayed getting out for no good reason. Tight connect lead to a missing bag in Hamburg. Waited two hours at the airport to get the bag from the next flight.

Crew could have been more helpful in helping to find location to store luggage in overhead bins in order to expedite seating. Seating was cramped and uncomfortable.. Other than that it was a standard flight.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Had a delayed flight that caused me to miss all of my flights. Supposedly I was rebooked. When I got to my next connecting flight there was no ticket for me. I spent hours working with an agent. And they still couldn’t get it right. I will arrive home more that 24 hours later than my original schedule. Totally inept and frustrating experience.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

Very good, i got two seats for myself, and was comfortable with the blanket i got

Not to bad but it was hard changing my seat

Economy Priority seats are extremely uncomfortable. There is no way to escape the boxed in feeling, particularely because the distance between to rows are too short, the hard edge of the front row is keeping legs confined. There is no elevated place to put your feet. I am of average, European size.

Terrible. Both flights were significantly delayed, no luggage, made me check my small bag when many, many others had much larger carry-ons, not even a bottle of water . . . I will not fly Discover Airlines again.
