Does Beyond Pricing adjust for unusual booking conditions (such as Lockdowns and spikes) or could these skew my historical data going forward?

Yes! Although Covid-19 was on an unprecedented global scale, Beyond Pricing is accustomed to dealing with anomalies in data.
Things like hurricanes and algae spreads in popular beach destinations also cause disruptions to what would be a typical year for a market and the Beyond Pricing Revenue Management Team know how to address this.
