I was doing some checking to see how many people had the ticket for 815 bought or given to them, and not getting it on their own.. SO Far if I am remembering correctly

These People were Given Tickets to the Island
Claire
Sayid
Kate
Sawyer
Locke?? (went to do walkabout and couldn't don't know if he bought ticket or if walkabout did)
Jin& Sun (Jin was delivering watches for her father, Paik may have bought ticket)

There are a few off the top of my head.. When I can check my notes I will add to it
