My family has plane tickets for a vacation in that area next summer. I don’t know what to do. The plane tickets are a sunk cost.
Maybe you can sell them?
How long ago did you buy the tickets? Did they change the flight times or plane since you bought your ticket? If so, even if your flight time is changed by 1 minute, you can cancel and get your money back. I bought tickets to Baton Rouge for Christmas a while back, and Untied changed the arrival time, and I was able to cancel for free.
