It's not a full-blown recovery across the industry just yet - but the uptick in revenues in the second quarter for publicly listed digital travel providers was substantial.
For example, Booking Holdings and Expedia Group found themselves with at least three times the amount of revenue between April and June this year than in the corresponding quarter in 2020.
This should not be a suprise given the relaxation of lockdown restrictions that began towards the end of the first quarter in many key consumer markets around the world.
And, such a relatively buoyant quarter will help stablize the finances for some of the public companies, especially those that experience lukewarm quarters during the rest of year.
PhocusWire first produced its visualization of digital travel company quarterly revenues going back decades in November 2019.
The chart begins in 1995.
Several companies in international markets only report earnings on a half-year basis, which means their revenue numbers on the chart only change twice a year.
All currencies were converted into U.S dollars, using the exchange rate at the date of their respective earnings report.
