I've seen swordfishes and seaplane recons pointed out but haven't seen definite proof either. If they were giving significant bonus they would be confirmed by now, so it doesn't matter much anyway.

How planes are supposed to help finding fish? The same way experienced spotters are: schools of fish attract seabirds, so fishermen are looking for flocks of seabirds as a clue for where fish are. And you can cover much more of the ocean with a spotter plane than with a boat and then radio their position.
