SV has never had 742s in passenger configurations.
They used to lease them periodically from various airlines. Sometimes wet-leases and sometimes dry-leases.
I know they leased MEA
's 3 B742s for a few years.
It's a 4 digit flight number, so it is definately a special flight.
If it is a 742 indeed, then it is a cargo flight unless SV
is leasing a passenger 742 for the Hajj season.
Saudi Arabian Cargo does periodically operate cargo flights to Beirut, but they are usually on MD
