Hello all! I am flying from oahu to big island on August. Leaving oahu at 10:40 amand expecting to arrive at Kona at 11:23 am, taking Hawaiian Airline. The thing is I am considering to join stargazing tour to Mauna Kea Summit leaving King's Shop at 2:15pm on the same day. I will be staying Hapuna Prince and I am hoping to find time to go to hotel to drop my staff before heading to King's shop. My concern is if the flight get delay, I will miss the tour. Are they usually on time? I will be in the island only for 3 days that's why I am doing this. Any suggestion will be helpful. Thank you in advance.
