London to Chicago on AA. Are changes now allowed with the Web Special award flight? I paid 36k points and 190 USD for round trip. I’d like to delay my flight until the virus slows down. 

For my return flight, it cost 17k points. 

I know originally changes are not allowed, but cancellations are with a fee. 

What options do I have? Ideally I’d change the flight without paying extra. If i have to cancel and rebook (I believe the fee is waived), would part of the taxes paid be refunded?
