Where others are large and slow you will be small and flexible. As some pairings close others opens up. People are just booking short time out anyway so you don't have to publish a 6 month schedule. Many airlines take a week or 2 to react to government advisory changes. You should have it ready for booking by tomorrow. And most customer charter rules are temporarily suspended or not enforced so a 2 or even 1 week cancelling policy should be envoked. Cancel, refiund and move your resources to a different rote. As a new airline you are not lumbered with bookings done months ago that you want to fly to avoid refunding because you have spent the cash from them on paying for unused planes and other fixed costs.
