final summary not calculating properly

what program is meant to do: this program is a airline booking system where seats are booked, each time it is booked it is in a session, the final summary must add all the session summary's up and give the final figures.

problem: the problem I am facing is that the final summary does not calculate properly and I am wondering if anyone can advise me on as why it isn't calculating properly. All the code is needed and I cant make the problem shorter to explain the problem.

adult_price = 120
child_price = 60
availble_seats = 152

t_adult_s_s = 0
t_child_s_s = 0
t_total_s = 0
seats_left = 0
