To me, clickbait is along the lines of "10 ways to lose 100lbs in 1 hour!" and it's an article about throwing out two 50lb weights. Or otherwise where the title is clearly not representative of the article itself.
But here we have...
>Effectively immediately, Heathrow has requested:
-the closure for sale of all flights departing from the airport until 11th September
- a reduction in the current passenger cap from 101,500 to 100,000
That seems to match the title exactly? Which part is clickbait? Or what has changed in the definition of clickbait that I'm too out of touch to have learned?
