COVID cancellation EXCHANGE question

I would still ask, because you have nothing to lose by asking. But I would say, they will refund you and you will have to repurchase the tickets at whatever the price is. I don't think (98% sure) they even exchange discounted tickets.

Since the show was last Tuesday, I’m assuming they automatically refunded everyone’s tickets already. If you purchased online, you can check the order status on the Telecharge website, to see if that’s the case. Fortunately, Come From Away still has an active promo code, so, hopefully, you’ll be able to rebuy at the same price anyway.

I exchanged a Flying Over Sunset ahead of time in person at the box office, and they were very nice to give me the discounted rate for the replacement ticket. Whenever I want to do something like this, I always go in person when the box office is not busy, and be very nice to the box office employee. I can't imagine they would not honor the price, as they will be begging for business in January.
