Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.

Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.

Decent flight, helpful middle seat blocking in business. Boarding staff was polite and helpful. Unfortunately the airport directions to this gate were a mess and the check in staff did not alert us to the confusing signage or any proactive information about the lounge. On board the flight, food and drinks were decent but average. Comparatively, SASs new business catering on this route shines above both in quality and service

we originally had premium economy seats when we booked, but because we were forced to re-book because the first leg of our journey was delayed for several hours, we had to fly economy. Less room, less comfortable.

Flight was fine. We were in business class, so lie-flat seats were appreciated. Kids were in premium and said it was nice. Flight was delayed by 3 hours, so we missed everything we had planned in London the first day.

Gates were changed at Heathrow with nothing show on the board about 200 plus people needed to take a tram to another section of the terminal. At JFK airport, we had to wait 1 hour(!) on the tarmac after a 7 hour flight to get a gate to deboard!!

I am very disappointed with the way my seat reservation was handled. My husband and I purchased Business Class tickets and also paid extra to reserve our seats. However, our reserved seats were changed without our consent, and we were assigned different seats, separating us. Since we paid specifically for reserved seats, the airline did not provide the service we purchased. I would therefore like to request a full refund of the seat reservation fees. I would appreciate your prompt response and resolution to this matter. Thank you.

I can't believe you have to pay L 3.20 for a Cup of British tea on an airlines with the name British on the plane.

Long haul flight and was really good. Comfortable plane and seats. Really great service all round and always willing to help. Lovely food and drinks (Tanqueray is my favourite Gin). Media was great and helped for the long journey.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).
