How to unlock the Aerial Assassin achievement in BioShock Infinite - Definitive Guide
When you jump to the last hook, an enemy will walk below you and give you a perfect opportunity to Sky-Line Strike him. Do it, then reload checkpoint until you get it.

The Sky-Hook is obtained automatically whilst playing through the story in Chapter 3: Raffle Fair. There are numerous Sky-Lines throughout the game, acting either as a tactical option during battles or a method to reach your next objective. Whilst you are riding a Sky-Line, you need to aim towards an enemy with the until a yellow star appears beneath their feet with the words “Sky-Line Strike” appearing above their head, then press to perform a Sky-Line Strike. Some enemies will join you on the Sky-Line, and you can highlight them and perform the Strike in the same manner, which will also count towards this trophy.
Note that the enemy must be killed outright, so try to aim for the normal enemies who carry pistols or machine guns as they will die in one hit as opposed to the more armoured foes who take multiple Strikes. Also, if you find that you are travelling too fast on the Sky-Lines, try holding whilst on the Sky-Line to slow you down almost to a halt, making it easier to highlight enemies.
You can also perform Sky-Line Strikes from the static hooks dotted around Columbia that you can attach to in the same way as a normal Sky-Line. This might be a preferable option if you are struggling to target an enemy whilst moving on a Sky-Line. Thanks to F8l Fool for confirming.
All kill-related trophies can be farmed by restarting checkpoints or replaying chapters.
