Because the airport’s own site does: the VIP lounges page calls the two halves of the single terminal building “Terminal A” and “Terminal B”, the shops-and-restaurants page calls them “Ala Sur” and “Ala Norte”, and the rental-car page places its counters “next to Terminal Norte”. No official page ties these labels to each other, so treat each set of directions on its own rather than assuming they map onto the same split.
