I chose seating based on me being 6’3 and they changed planes I guess bc I got 2 random Seats that were middle and window and vert cramped and uncomfortable for a long flight….should have been able to get same seating just different aisle maybe especially since we picked them and weren’t random

Liked that our agent at check in changed our seats to allow us to have more space.

Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.

I was upgraded to Busines Class from premium economy which was a great surprise. But......the service was not marginally better than premium economy. After the welcome on-board drink, I only saw a flight attendant twice...... when she delivered gluten free meals. In between, during a 8 hour flight, she didn't check back with me to offer water or collect trash. I had to fetch my own! The gluten free food was not good - they gave me the same meal whether I was in premium economy or business class.

You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.

Check on was very hard. I believe my seats had been selected when I booked, but when I checked in I had to select seats. My previous pre assigned seats were no longer showing and I had to take seats I did not want. Check in took me forever. I also had to pay an additional 22/seat when I had already paid. Lastly thought I had pre paid for a checked bag., but that did not show up so I had to pay for a checked bag. 75.00????

My flight out of London was canceled on September 9. We could not get a flight to Italy until 2 days later. That means we would miss my son's wedding. So we had to take a train from Heathrow to central London (14 £ = $18.99). We then had to take the train from London to Paris (612£=$830.24). We had to take a taxi from the Paris train station to the Hotel Sixteen in Paris (€67.5=$78.67). Our hotel in Paris is (€340 = $396.26). Our flight from Paris to Italy was (€442.25=$515).
