Challenge an airline’s EU261 rejection with flight data

They used an agent to verify delay details, build an EU261 argument, and send a reply only after approval, which led to a €400 payout.

Done with Grok Bot· Intermediate· Oct 2026

What they did
A Grok-based agent was given access to email and asked to review a denied delay-compensation claim. It checked the flight record, found that the airline had pointed to crew rotation even though the weather was clear, and used that to argue the delay was not an extraordinary event under EU261. After drafting the response, it waited until the user typed “go” and approved the message before sending it.
How it went
The airline accepted the claim and paid €400 before the user’s flight arrived. The user only had to intervene at the final approval step before the email went out.
Tips
Keep the agent on a short leash: have it prepare the case and stop before any message is sent. Ask it to cite the flight record and the specific rule it is relying on, then review the email carefully before approving it.

My airline turned down my EU261 compensation claim for [flight number] on [date]. Check the flight status and related details, review the EU261 rule about extraordinary circumstances, and draft a reply explaining why [the reason the airline gave] does not qualify. Include the evidence, the compensation amount I should request, and a polished email I can send. Stop before sending anything that leaves my account, and wait for my approval first.
