I booked a flight on business for Aug 30 to Cairo from Toronto (MS 996) with the understanding it was 787 and 1-2-1 configuration. But checking the flight history, it shows 777 departures (2-2-2 config) for past week or two. Further confusing me, is this information from flightmapper, saying it's supposed to be a 787. Anyone know if this is a permanent change or is it a seasonal thing and I might get lucky before departure?

Thank you all!
