Upgraded to Business Class (Club World) with British Air when flying home from our trip to England in March 2012. Flight BA0099 on Tue. March 20, 2012. Flight was full and we hadn't booked seats for the return flight home to Toronto. Went to the BA Club lounge while waiting at Heathrow, went through 'Fast Track' to board the plane and sat in seats 11A and 11B in Club World. What a fantastic experience and so much fun!
