Since the corona virus anyone experienced any flexibility in standing by for a flight on an earlier day when the ticket is a non refundable ticket (A). Due to fly LHR - JFK on March 17 but with what's going on would be happier getting home sooner. Happy to stand by for the 15th or 16th if BA is being more flexible with 'non changeable' tickets. Don't think my status as emerald will help but if anyone has any recent experience in changing a 'fixed' reservation would be interested to know.
