It's been a few years since I've been to Gatwick. It's reported, London Gatwick is the most stressful airport in the world! It's the UK's second biggest airport. Although the number of passengers that use Gatwick is below average compared to other airports, it has one of the highest passenger density scores! It's percentage of annual delays is the second highest of the top ten.
If anyone is going to the UK from Vancouver, British Airways has direct daily flights to both Gatwick and Heathrow this summer.
