If that was a question in an airline company interview, then I guess you have navigated away from the area where the interviewer was trying to get you flying at!
Probably you were stuck with it, and so do many others, naturally. There is no definite answer for the question unless you ask some questions first. For instance, what did the interviewer mean by the word "easier"? For the pilot? For flying the company routes? What routes do they fly? N-S or E-W? Crossing hemispheres? Many many variables here.. But guess what.. Aeroplanes with an FMS fly Great Circles effortlessly! Why? Because great cirlces are the shortest way to connect any two points on earth. Meridians are great circles..! & while shorter distance means less fuel plus saving the aeroplane's profitable operating hours, it could be easier for the company too! Does that make sense?! Apparently what could be easier for the aeroplanes to do would be easier for all! So I guess the interviewer was just playing a little game with you trying to present a problem that could have several solutions and probably he is not looking for a particular one, but is rather waiting for you to choose any solution in your head and throw it back to him with good reasonable justification.
Good luck.
