Hey guys!
I noticed that above every callsign, there is a small number. Could someone please briefly explain what that is? Thanks!

That is the altitude difference! +60 means they are 6,000 feet above you.
If they are lower, there would be a “-XX”

That is to indicate how many flight levels the aircraft is above or below you.
For example, whatever altitude you’re cruising at, Alaska 57 is cruising 6,000 feet higher, and C-GFFD is cruising 2,000 feet lower.
