Two ways to do that are risky
a) go out to aircraft alone - risky someone may question why or caught on cctv
b) have it in pocket whilst loading (or unloading bay), you may get detected with it or placing it.
If a bomb in that compartment it was almost certainly in baggage, enough reports that scanning was inept at best.
Thinking ahead:-
I am ony aware of 1 bomb that was placed in an aircraft (toilet) as opposed in passenger luggage (inc cabin)
If this were to turn out to be the scenario, the question of on ground aircraft security arises, to the best of my knowledge no external hatches or doors are lockable perhaps they will need to be made secure in some way.
Remembering the reactions to 911 will we see something along these lines.
Aircraft having a alarm system like a shop set by crew on leaving, can only be reset from flight deck which is locked, so access not prevented but is known.
Perhaps an extra ad hoc cabin crew member who does not leave until cleaning, refuelling, cleaning, baggage unloading is complete is complete, same person would have to be there prior to main crew to give access to catering and refuelling (if not done earlier), sort of like a junior crewchief.
