Can someone explain why elif is being ignored?

I'm very new to programming can't wrap my head around why my elif statements are being ignored. Can anyone help?

prompt = ("Enter your age to buy a ticket ")
prompt += ("or type 'quit' to end the program:")

while True:
    age = raw_input(prompt)

    if age == 'quit':
        break
    elif age < 3:
        print "Free ticket."
    elif age < 12:
        print "$10 ticket."
    else:
        print"$15 ticket."
