That NOTAM only covers part of the Sinai Peninsula, not the whole of Egypt.
The UK issued NOTAM is clearer on the area boundaries:
Hazardous Situation in Egypt Potential risk to aviation overflying Egyptian airspace in Northern Sinai Governate within the area bounded by 311400N 0322200E - 294000N 0324000E - 293000N 0345400E - 312000N 0341200E - 311400N 0322200E (Cairo FIR, Sinai Peninsula) at less than 25,000 ft above ground level (agl) from dedicated anti-aviation weaponry. Operators are strongly advised to avoid operating at less than 25,000 ft agl in this airspace.
The US FAA NOTAM includes the following:
C. OPERATIONS. EXERCISE EXTREME CAUTION DURING FLIGHT OPERATIONS DUE TO THE RISK FROM POTENTIAL EXTREMIST/MILITANT ATTACKS INVOLVING ANTI-AIRCRAFT WEAPONS, INCLUDING MAN-PORTABLE AIR DEFENSE SYSTEMS (MANPADS), ANTI-TANK MISSILES, SMALL-ARMS FIRE, AND INDIRECT FIRE FROM MORTARS AND ROCKETS TARGETING AIRCRAFT AND SINAI AIRPORTS. THOSE PERSONS DESCRIBED IN PARAGRAPH A MUST REPORT SAFETY AND/OR SECURITY INCIDENTS TO THE FAA AT +1 202-267-3333 OR 1 202-267-3203. THE JUSTIFICATION FOR THIS ADVISORY WILL BE RE-EVALUATED BY 30 MARCH 2020.
Operators are not "barred" form the area either as you state, as the wording of the Irish NOTAM says "should not", therefore it is only a recommendation.
Obviously, BA have received some information from the security services of a potential threat. That's info isn't going to be publicly disclosed.
As some one else said above, I can't see why anyone would want to travel to Egypt anyway. Or any of north Africa from Morocco to Egypt for that matter.
Been in every country along that coast and I've no intention of going back to any of those sh1tholes ever again.
