5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

West Jet has a horrible boarding process and the seats have no cushion.

Second time I took this flight, and they lost my luggage both times. Waiting for my suitcase now, last time it took two days to get it back.

Everything could be better. The plain was in Orlando for 3 hours prior to boarding. After boarding all the passengers they found out that plane has a mechanical problem. After an hour the problem was solved, the pilot comes on and states, (We have to go back to the gate and take on more fuel!) Are you kidding me???? Who they have for pilots, Boy scouts?? I barely made my connecting flight to Vienna, but my suitcase did not. I'm still waiting for it, in Gyor, Hungary. Am I having fun yet?? Other passenger were in the same binned. I travelled all over the world both for business and pleasure with all types of airlines. By far of all the carriers I travelled with, Discover is the worst. I'm contemplating to bight the bullet and go back to the US with a different carrier. For International flights, the seats are made for little people. The person in front of me had his seat reclined the whole way, I felt like he was sitting in my lap. For closing, I would not let my dog travel with Discover, yet alone recommend it to an other person. Does it sound like I'm frustrated, Think about having to travel back to the US with them. I'm sure I'll not hear back from you, because nobody wants to hear about bad news, but with all the hype Discover puts out there about their services, nothing could be further from the truth. Joseph A. Nagy

Only problem we experienced was not anything to do with Lufthansa. When changing planes in Frankfurt we spent over an hour on passport control line. Lufthansa did a marvelous job on everything from keeping me informed via texts, to terrific cabin crew.

Bordón could be bettet if the company say before boarding the order of the different groups.

Checked in is easy and it was a smooth flight from LAX to Munich

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.
