Speaking on 大象传媒 Radio 4's Today programme, the airport's chief executive, Colin Matthews, said Heathrow had invested 拢36m in snow-clearing equipment and was "in no way in the same position as 2010" when a runway closed for nearly four days.
He said two-thirds of flights operated on Monday and nearly 90% on Tuesday.
"I'm really sorry for every passenger who got caught up with the disruption and the cancellations but the fact is when it snows we have to clear the snow off the runway," he said.
"It takes us a little time to clear the snow off and during that time we can land less aircraft and take off less aircraft than in normal conditions and therefore because we are full any amount of snow is going to cause some disruption."
