Sorry to be so negative but I am / WAS an "old" Ghana Airways sucker for punishment ...
NEVER, EVER trust them with ANY THING ... so yes they are / might be the only one's doing that route so be prepared NOT to fly the day / date that was issued to you.
Yes they did have a "schedule" to Bamako the last time I was there. I think Million Air still did that route.
3 weeks ago ... 1 one of the 5 "schedule flights" from Accra to Freetown arrived .. never mind on time / date ... 4 did not arrive bru
So yes and NO ... Phone Millionair in Jhb they will most probably be the most helpfull.
Cheers (and lotsa luck)
