Oops, try again. plane_ride_cost('Charlotte') returned None instead of the correct value 183

I am getting this error. I don't know what is the error.. This is my code:

def hotel_cost(nights):
return 140 * nights

def plane_ride_cost(city):
if city == "charlotte":
return 183
elif city == "Tampa":
return 220
elif city == "Pittsburgh":
return 222
elif city == "Los Angeles":
return 475

def rental_car_cost(days):
cost = 40 * days
if days >= 7:
cost -= 50
elif days >= 3:
cost -= 20
return cost

def trip_cost(city,days):
return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city)

string comparison is case sensitive, 'Charlotte' == 'charlotte' is false
