This month alone I have flown 3 trips (6 flights) where both sectors had flight time over block time in three cases in excess of 30 minutes. This is due to airspace closure. Costing me about 4 hours of flight pay. This airspace has been closed for more than a month now. This same company can find 3 aspirin on a 4 page hospital bill and payroll deduct the 6 dhs., due to the "over the counter" clause.
