after 2 months of waiting: no nothing

Homeland security send me a standard letter, which I interpreted as "no harm done" but British Airways did not reply in any way.
People, stay away from London. It's a disaster, a chaos, a nomansland you don't belong to, a country you should avoid if your brains are intact. Don't fly with them since you'll be misunderstood and mistreated, like the 3rd class Titanic clients were.
