London Gatwick (LGW)

You can smoke outside the terminal buildings in the designated zones which are clearly marked.

There’s no smoking once you’ve passed through security and there are no smoking facilities for passengers connecting from an international to international flight. However, at South Terminal, the My Lounge airport lounge features an outdoor terrace where passengers can smoke if they wish.

E-cigarettes have the same restrictions and can only be used in the designated areas outside the terminal buildings.
