No assumption was necessary. A simple Google search revealed that Egyptair uses AMADEUS and as such checkmytrip was the alternative to the airlines website which I had already used.

I called Egyptair in the US. Turns out I had to use the passenger's first name for some reason in tandem with the PNR as he claimed that's how it was in the system. Not sure what that really meant because I did sign in (using first name) while talking to him and the passenger names are listed correctly in all tickets. On querying the need to sign in with the first name he was quite nonchalant in stating that was how it was in the system and that "first name, last name, they don't really cares...there is no problem."

Upshot is I can now access the reservation on both the Egyptair site and checkmytrip to monitor any changes to the flights which are almost 3 months away.
