I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

It was a short flight, everything was good with it.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Stop charging for alcohol overseas flights and start taking cash again not everyone wants to pay with card if the person is bigger give him seat on the outside seats not the middle in between the people is common sense and mainly if you fly for Lufthansa provides the sam service and experience...

good entertainment package but rather small seats for business class

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.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

Much much better than my previous times on British Airways the food was spot-on and the service was really genuine and attentive

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Didn’t fly with them as someone had cancelled my flight

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠

Boarding was efficient and quick, crew was very attentive, seats were comfortable.
