@ Andrew:
Since Jan 10, 2010 they stopped operating LHR-TLV, so I'm not sure if this reasoning is correct, as other places they stopped serving, such as AMS-LHR, they abolished much faster.
The BMI deal between TLV-CPT is so good that if some fees are going to withhold you from using them, you should be locked up in an institution.
Very little mileage, which you could do part cash/miles, and every direction you could visit europe + if supposedly your destination is mauritius, you can fly there also.
