Overall Summary
Safe
  Why we think so? 

🛡️ Costco Travel looks like a legitimate, well-established travel service tied to Costco. The domain has a long WHOIS history, a valid DigiCert EV certificate, strong traffic at roughly 7.4M monthly visits, and no Safe Browsing or crypto blacklist hits. It also has a physical listing in Issaquah, WA, plus official contact channels, social profiles, and business-grade infrastructure like Akamai, Microsoft 365, and Adobe. The main caution is reputation, not authenticity: reviews mention long hold times, refund friction, and inconsistent trip experiences, so you should read the booking terms carefully before you buy.
