We have actually flown this same flight previously, last time in economy. This trip we were in business class upstairs on the Boeing 747 experiencing British airways unique front to back seating. Pre flight the lounge was the same as last time. Previously flying economy we had lounge access via Priority Pass this time due to being in business class. The seat is very different if anything it does not feel as wide as the Qantas Skybeds but there is plenty of legroom. the window seats are private the isle seats not so and window seat passengers may need to step over isle seat passengers sleeping dependent on the row.
Service on board was great during the flight.
Wish something could be done about Heathrow arrivals.
