Kingston normally doesn't get arrivals overflying. It's just inside the GASGU/Ockham departure NPR swathe when Heathrow is on easterlies, but traffic on that route normally overflies Bushy Park, staying west of Kingston.
Edit: I've just had a look at the last day of pure easterlies pre-lockdown, and around 6% of 621 departures used the GASGU SID, mainly those to Iberia, Central and South America, plus some (but not all) of those bound for Miami.
