On the 29th of January 2012 Virgin Atlantic operated the first commercial A330 service from Heathrow! G-VKSS arrived from Gatwick and was prepared for its flight to Nairobi. It arrived back at Heathrow the next day. From here it went back to Gatwick and then carried on it's usual services to Orlando! The A330 hasn't been back to Heathrow to operate another Commercial service since!
Virgin Atlantic now operate the A330 on a Daily flight to JFK on the VS3 route.
