the one time i flew them, i found the customer service awful, but it may just be the ground agents in dakar that i was frustrated with. after flying EWR-LIS-DKR, they told me my bag did not make it onto the plane, despite a 12-hour layover in lisbon before.
they said to come back the next day, as the bag would be on the next flite. went back to the airport the next day and no bag. the next day, same thing. i then had to travel to a remote village with no communication, so i told the ground staff i would be back in a week for my return flight and please just hold onto my bag in DKR until then.
when i got back to dakar and the airport for my return flight, they told me they couldn't find my bag. a little upset, i walked to the baggage carousel and opened the flaps to stick my head outside to yell some choice obscenities. there, about 100 yards away, i saw my bag sitting by itself on the ground
