Airline reviews

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

Flight crew was very cold and stood around a lot talking to each other.

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

On time, only a little turbulence, very competent and caring attendants. Clear information.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

On a four hour delayed flight now on seats back end of the plane instead front-

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

Economy seats a bit small but other than that it was all good.

Boarding was very good, crew attentive and friendly, seat size comfy, screen size nice. However, the seatbelt segment with the buckle is extremely short, which made fastening the seatbelt very complicated. Moreover, the bluetooth pairing of the audio system didn't work. It was not possible to have proper audio. The flight info software didn't work, too.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

They messed up my seat so I didn’t get the one I paid for

Put me on standby; flight was late; missed my connecting flight; disaster

My flight was delayed on my way to Germany. Luckily I was able to contact the airline and rebook my connecting flight. Some other passengers, who didn’t rebook, missed their connection.

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

I never made it to Rome, therefore I never made it to the Lufthansa flight. Air Canada cancelled its flight out of Raleigh Durham, I missed the connecting flight out of Toronto and after other airline mishaps took place and I had to give up getting to Rome and dissappointing the friends and family waiting for e in Rome. I am currently trying to get reimbursed.

Crew was professional, attentive, and delightful. However, the plane was delayed more than an hour. I recognize this was not Lufthansa’s fault, but was inexcusable was that there were no Lufthansa reps meeting the plane to give quick info about gates for connecting flights and how to navigate getting to those gates, especially when it required going to another terminal, going through security, and then returning to the original terminal. This was egregious - other airlines routinely do this when an arrival is significantly delayed.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.
