@Cerulean, did you pay for your flights with a CC? If so, you should be able to put in a claim with them to get your money back.
We’ve had 5 trips cancelled this year, and in each case, got our money back. BA were trying to get people to accept a future flight voucher, but we refused and said we wanted the money back and got it. We were due to go to Sandals in March, and the day before the flight, it was cancelled. We had to wait a few weeks, but Sandals refunded all our money.
In one instance BA were dragging their heels refunding us, so we contacted the CC company and the money was refunded the next day.
Lots of the companies now have included Covid clauses, so that if you have to cancel, you can get a refund. Of course, if they go out of business that’s different, but we always pay for any large item with a CC and have always got our money bacK.
