We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

They allowed some guy to move seats after 3hours of him being next to someone very sick, There were several empty seats, but they moved him to mine. I find that incredibly inconsiderate and should not have been done.

Excellent. Very nice and comfortable business class. Only negative is that it was difficult to hear the pilot’s announcement.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Check in was horrendous! Economy took 2 hours before seeing an agent. Business class was 0.5 - 1 hour.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa
