Airline reviews

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

During the flight there was a medical emergency. We were diverted. Of course I'm thankful they cared for the health of that passenger, but they did a poor job of communicating with the rest of us passengers. In the end we arrived at our destination several hours late, with no direction of how to rebook missed connecting flights. It all worked out in the end. Those of us that needed accommodations were put up in a hotel by Lufthansa until we could make it to our final destination. But it was United Airlines Personnel who really helped us navigate the process.

Our flight to Chicago O'Hare was delayed an hour, causing us to miss our connection to MSP and spend an extra 3 hours at O'Hare so we could board a plane with a damaged door and wait another 45 minutes or so. The crew was great, the food decent, The drinks were great: 2 glasses of a nice South African Shiraz, an ice cold can of Beck's Beer, and Dewar's White Label on the rocks.

A350 has great entertainment. Make sure to watch the plane's external tail and nose camera's on landing and take off. Seats were a little hard for a 10 hour flight. I am gluten intolerant, they had good alternative meals for me on the flight.
