alt Hacker NewsHeathrow is by far the largest airport in the UK, with several times more flights per day than any other, and flights to a broader range of destinations. So it affects a lot more prospective fliers. I looked up European airports and found some mention that Rome and Milan also have this new equipment, but they're both still significantly smaller than Heathrow.
Gatwick already had it too, at least a part of it.
The fact Heathrow got 30/40% more traffic than other airports in the same continent already having it doesn’t make the news worth all this noise.
