Re your Request for Angola
We always used CELTA
First started Overflying Angola 1995 and use CELTA Never any trouble whatsoever they are nice to people to deal with .
We one diverted to Luanda en route to Lanseria and thougth we would have untold problems..
One call to CELTA and they were there to meet the Aircraft with a Fuel truck.
Crew Never left the A/C The only delay was the time it took to put the fuel in .
All Charges paid for by CELTA including fuel
Chox on 2 Chox off 25 mins (Beat that if u can in Africa)
Nothbound from S A if winds were not favrorable we used to Plan Luanda as it was so easy Day or Night they would be there awaiting your arrival and it saved you diverting further on the Flight

NO I am not Celta s Rep in the UK
