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.

2.0 Poor

Chad, Sep 2026

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.

10.0 Wonderful

Verified traveler, Sep 2026

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????

2.0 Poor

Verified traveler, Sep 2026

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). The bills are attached. Sent from Yahoo Mail for iPhoneInline image Inline image Inline image Inline image Inline image Inline image
