If you are interested to enjoy the best and cheap flights, I suggest you to travel with Air Zimbabwe . Reason behind is that  I personally found Air Zimbabwe the best as it provided high quality service on very cheap rate. Yes their rates were really very cheap as last year,  I booked a Business Class flight to Bulawayo with Air Zimbabwe in just 650 GBP. Not just the rates, the extreme Business class facilities of the airline are just perfect. Thanks Air Zimbabwe for making my journey a memorable one.
