Flying out of mackay to mccall is $470 for a small plane that can fly 3 kayakers and lite gear. They only fly into mackay in the am and out in the pm. Due to high temps in july and august. So, if you fly out of mackay, you get to mccall around 9 or 10 pm. I just happened to make said arrangement last week. I would consider a jet boat shuttle pre or post trip. Pre trip shuttles give you a look at the river b4 u run. No matter how you slice it up. The main shuttle is going to be spendy.
