The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Booked Economy but it translated to economy light for Lufthansa so now we are stuck paying an extra $75 per person both ways for our checked bags. If I had known that, I would have never booked these tickets because it came out to be more than other options. The booking in the kayak side clearly says Economy and has a link to the inormation for Lufthansa which states Economy included a checked bag. Super annoyed about that.

The flight from Dulles to Munich was just okay. The seats were comfortable and extra foot room was noticeable in comfort plus. Disappointed in the booking in so much I requested an aisle seat and then was assigned a middle seat. The food was inedible. Movie choices were moderate. I usually fly Delta, but this WA flight was cheaper. Next time, I'll happily pay the extra to fly Delta.

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

We were upgraded to economy plus and everything was awesome!

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Hate their old flights, boatding, food and services. Very poor quality
