Most airlines are not. We've gone through this ourselves as of recent.
Covid travel policies have been rescinded across the industry.
You'll get future travel credit not necessarily a refund with the major legacy carriers. However if you ask nicely enough, it's amazing what can happen.I just cancelled one flight and amended another with JetBlue with no issues and did the same for United as well. No penalties at all. Not saying you are wrong. Only giving you my recent experience literally weeks ago.
Gone however are the change penalties. You're just responsible for the fare difference. Either way the airline still has your money, so their happy about that.
