how do you get a senior discount of tickets at the machine. Do teachers get a discount

Ask the discounted tickets counter inside

Talk to the person in the inside for discounts

For any discounted tickets you would have to go to the courtesy counter inside. They would give you your discount if you were eligible for it . usually no line.

AMC doesnt offer teacher discount. You might want to try the AMC A List though. Thats a great discount.
