SLL Did not go back yesterday as originally planned. There was some snags to be fixed on EI-FAS and it has been delayed untill near the end of the week.
The 500s are probably the most expensive in the fleet and they are more than 5 years old now. They have been giving trouble recently and therefore the decision was taken to sell off the big assets.
REP is awaiting its engines to come back from overhaul and then it will be flown out of the country. With 8 600s on the way, and the option for 2 more, they will no longer need all the 500s.
I do think that it was a silly move! But hey..
