I’ve always known that the key to award travel is flexibility. The best deals are on seats that are going to go unsold. An airline doesn’t always know what seats those are, and may play it conservative not releasing award space until very close to departure. And even then they may be reluctant, worried that someone might redeem miles instead of spending big money on a ticket.
Right now uncertainty is even greater for airlines. How many people will be traveling? Will there be any business travelers, or will it be all leisure? Will there be restrictions on actually flying to a destination? Or perhaps restrictions on the number of flights a week that can be offered?
