Just tried replicating it in Firefox, and it seems that Chrome and Firefox accept different certificates for airbnb.com. Tried on three different platforms (Windows, Ubuntu and Android), same thing: Firefox uses a valid GlobalSign certificate, while Chrome uses an invalid DigiCert certificate. Never seen the same website using different certs for two different browsers before.
