The following week was similar apart from Tuesday, with more Scandinavian flights, which seemed to follow a 3 week cycle.
The OM150/151 flight (and the OM200/1 on Sundays) was to Tel Aviv - there was much paranoia about displaying the destination anywhere, so all the check in signage and flight information boards only showed the flight number. Staff were under strict orders not to say "Tel Aviv" in front of the public or - even worse - over the hand held radios. Same applied to aircrew communicating on the company ops frequency. Not sure about ATC - possibly it was "Monarch 150 cleared to destination as filed".
