Airlines, Banks and Retailers Block AI Agents as the Web Closes Its Gates

Major services including Yelp, Delta Air Lines, United Airlines, JPMorgan Chase and Charles Schwab are blocking AI agents from booking tickets and accessing accounts. Some blocks stem from anti-bot checks and Cloudflare's September 15, 2026 default change rather than deliberate company policy.

• Yelp admits agents only under paid data licensing deals
• JPMorgan and Charles Schwab block agents over security concerns
• Cloudflare began blocking mixed crawlers by default on September 15, 2026
• Amazon is suing Perplexity over its Comet shopping agent under the CFAA
