I poked around and found that there are 2 MS RJs Egyptair Express--yours and the next at 8. A320 is 10:30pm. Are you talking about 4/26? BTW--congrats!
When you check in for MS ID--watch your ticket coupons, Their super took both--but I caught it. They hardly know what to do with nonrevs They tell you if it looks ok or not and send you over to a window opposite tkt counter to wait. Super comes and take you onward (or not as in our case--back to buy tkts for next flt)
****This is out of the box idea: ATL/AMM then zed med on Royal Jordanian nonstop to SHH (I would guess it requires overnight AMM)****
Returning--we got lucky about seats to NY then saw how we'd be stranded with that last Feb storm (we were soooo right) That's why we did the zed AF to CDG and straight to ATL on DL (backup was next day nonstop CVG(home)
