AK from BB, correct play or was I just lucky?

Thanks goes out to UTG+1 and MP1 who contribute 1 SB each and then fold pre-flop. The flop misses me completely, but it can't be of much use to anyone else either (there could be an 87 or 98 out there). With the pre-flop raise a bet seems to be in place, right? Two folds. Nice. The turn card feels relatively safe as well so I bet out again.

Did I just get lucky here that the opponents folded their hands, or was this the correct way to play AKo with this type of flop/turn?
