I can see that JIB is still a question mark.
Happy to report that passengers can use the Air France lounge at JIB.
I was on a KQ flight so I can’t comment on the specifics of the AF flight, but I can say the following for sure:
The lounge is after gate 1 security and opens c. 1 hour before boarding time
There are c. 25 seats so it must get really crowded before the AF flight
Good selection of beverages, food consists mostly of mignardises and is not super filling
The bathroom is really shabby, don’t plan on number twoing at the airport
Lounge entrance
Bar area with snacks, beverages, and newspapers
Another sitting area
