1000 feet vertically and 5 nautical miles (10 in oceanic airspace) lateral separation with speed control and one-way systems utilised too.
Aircraft also have onboard computer systems called TCAS so that each aircraft knows what’s around it and if anything even looks like getting too close screams at the pilots. Air Traffic also have similar systems on the ground.
It’s very clever and extremely safe - the sky is a big place!
I heard a pilot once say that the chances of two planes meeting in the sky was basically nil but the job of air traffic control was to put them all much closer together to increase the chances. For example if I wanted to fly to New York I’d follow the M6 south, pick up the M54 then the A458 until I got to the sea then I’d then stop and ask for directions. You might take the M62 and keep going straight. I’d barely see you let alone run in to you.
