I think we travelled on the 777.
Check in was seamless as was private security though the latter is reflective of the airport. No long queues with either.
BA should offer a chauffeur service and also reconsider payments for reserving seats - given the price of the tickets to then have to pay at least £83 each way per person is ridiculous.
No delays, both flights were on time.
The lounge was extremely spacious - no struggle to find seating although it was busy circa 07.00 - 08.45. The lounge had free massages available, vast array of non-alcoholic and alcoholic drinks, wi-fi business centre but they must, must, must improve on their food offerings - this is not on par with some other airline lounges i.e. American Airlines, Emirates etc.
The staff were very pleasant, engaging and do all they can for you.
The food on the plane was unfortunately just edible - I expect better given your spending thousands on one ticket and the standard of food definitely does not reflect this. They also did not have our desired choice on our return.
Good amenities from the White Company provided - unfortunately no PJ's this is for First Class only. You also have to prepare your bed yourself unlike some other airlines.
2 middle centre seats are perfect for couples - I would feel very uncomfortable sitting here with a stranger and would opt for a one of the two 'single' seats that face opposing ways.. We sat in the seats closest to the curtains separating the classes. I personally would sit as far away from the bathrooms as possible. Also the 2 single seats closest to the bathrooms - the bathroom door obstructs these seats so I would steer clear of these. I don't feel the design of the business class seats were well thought out. When food is being passed to you depending on where you sit, another individuals food will have to be passed over your seat.
Bathrooms are no different to economy although White Company products are provided in the bathroom.
