Luckily i escaped that day by parking further down closer to the entrance. I normally park in the flooded areas....
If I was one of those few with written off cars i'd be getting my insurance company onto the BAA. They're liable and there's definitely no signage to warn of flood risks.
I was also never made aware that area was a flood risk when i collected my car park pass from the BAA offices.
To say its the airlines fault is a joke!
