ignoring your trick question (90 mins vs 1.5 hrs) here's an honest answer :)

flying east to west is shorter than west to east? why? headwinds and tailwinds. but for this to really factor in the time of the flight will have to be long (like 7+ hours). if you frequently fly to the far east like HK, SG, Phils, Japan etc, you'll find that returning takes approx an hour longer.

in the southern hemisphere, the opposite is true i.e. flying east to west is shorter.

lols got me there

but in reality, travel time going and coming back would differ

the correct ans is:

time difference and earth rotation.. these two factors effect the timings.

hawker is there any difference in the time taken in the 2 cases mentioned in the OP?

hahahahahaha ok, ok.

the stronger the headwind the longer the travel will be, simply because it goes against the aircraft which reduces the speed and makes time travel longer. plus add up the air-traffic on a certain area, the aircraft would be directed by the air traffic controllers to take certain routes/height to avoid collision in mid-air and if there are a lot of traffic on gourd (i.e take-off and landing) it could also add up the time.

install the flight radar and see the air traffic then you might get your answer.

Depends on the speed of the plane, the route taken and on long haul flights on the wind direction.
