Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Kayak notifications are therefore unreliable and pointlesa

Usual issues with flight delay. Perennial problem of travel by plane.

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The flight was delayed for over 1 hour. The boarding process is appalling making you wait for 30 minutes in the passage leading to the outside door without any seats.

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

Well Is extra charge for everything and other companies include that and the price.

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

British airways has the most uncomfortable coach seats for international travel i have ever experienced. There is no leg room and when the person in front of you reclines their seat it nearly hits you in the face. There is not enough room for you to open a laptop in front of you or eat a meal. It’s ridiculous and i hope to not fly them in the future.

No gate was assigned until 5mins before boarding so left us running to find it. Then over 2 hours on runway. First due to weather, which was understood, but then over 1 hour for something that wasn't really a problem. Poor communication between ground control and flight crew. The flight crew was wonderful. British airways will be on list of airlines to travel again.

I just have to say everything was ok, nothing special, and business class is not as good as it used to be, business class sets are the same seats as the rest of the plane including leg room, only difference is no one is sitting in the middle row, they put a janky little table in there to give you somewhere extra for the free drink to sit

First flight was 2 1/2 hours late. Had to wait in line on the tarmac for 45 minutes to finally board. Missed connection. Had to wait in line another 2 1/2 hours to get booked on another connection the next day. Another hour wait to get a hotel room for the night. 1 1/4 hour wait in 55 degree temperature for hour bus ride to hotel. Hotel ran out of food. Miserable performance by BA. This is being written while waiting for bus back to Heathrow.

British Airways is fantastic. I am low-vision and they were so helpful and accommodating. The food was all surprisingly delicious. That was an unexpected treat. The best of everything though was how helpful and friendly the service team was.

Business class in Club Europe is basically a slightly larger seat, with the middle seat blocked off. Not really business class, except for the free food/drink - which was also delicious!

Our first flight was cancelled. We later hear from London security that it is common for British airways. My wife’s return flight was delayed as well. Seems like there are operational issues with them. This makes me reconsider flying w them in the future.

If I have to decide again definitely I will pick another Airline…..British Airways NO MORE.

Flight take off delayed 30 minutes; arrived 15 minutes late. Had to take bus from terminal to plane, delaying boarding and unloading.

The mushroom rigatoni was very flavorful & made me happy. The flight team was accommodating and friendly & I look forward to using BA again in the future.
