But now that prices have more than caught up with travel enthusiasm, demand is tumbling, and as BofA airline analyst Andrew Didora writes today, system net sales (i.e., total bookings) took a sizable step back this week to -23.6% vs 2019 for the week ending 8/21 (compared to last week's down -9.3%) the biggest drop since February. System volumes and pricing decelerated to -23.5% vs 2019 (vs -11.5% last week) and -0.1% vs 2019 (vs +2.5% last week).

As Didora explains, "we typically only see this type of weekly change around holidays, so the change is surprising. The only comp issue we have found is that in 2019 Hurricane Dorian was approaching the US at the end of August, which could have pulled forward some bookings."

Some more details on the recent plunge in bookings:
