Yes, certainly AA seems to have updated its scheduled over the weekend. I had a LAS - LAX flight booked for mid-April and that has changed, with AA now only operating a single direct LAS - LAX service. I also had a LAS - DFW flight (connecting onto BA192 to LHR) change by an hour or so. However, given that Trump has now indicated that social distancing in the US will continue until the end of April at least (and not Easter as he previously intimated) I would certainly expected to see more schedule changes over the next fortnight or so.
