Between December and April BA operate a saturday flight to BGI.
It used to be December to March, though it went on to May in 2000.
Sometimes extra flights on a Sunday, but not so far this season, though the flights are full.
The BA273 departs LHR at 09:30 arriving BGI at 09:45, flying time just over 4 hours.
The BA272 departs BGI at 11:45 arriving LHR at 20:00.
There may be extra ones after April, possibly in August.
No charters now, though if any do happen BGI is a likely destination.
Very different to JFK services, a fun atmosphere though many use it the start their winter break in BGI, then return, every year.
80 pax restriction, as BGI is on the limit of Concorde's range, plus lots more baggage for this vacation destination.
Concorde makes a profit at 35-40 seats, so easy to see why BA are keen to do this service and even increase it.
