Which aircraft are you using? I've read the Buzzard is the best choice for the achievement.
What annoyed me with the knife flights is that the recommended plane was the one at the airfield you get from purchasing it as Trevor, but every time I went to use it, it would start a mission. Also, I'll bump this in case anyone didn't see it, but for Maka's 15th knife flight, you do NOT have to go through that tiny, tiny area. You can just fly through the buildings to the right of it instead and it works.
