Change a flight to a cheaper date and move the clash
The poster says Grok Bot found a better deal on a flight he had already booked, called the airline to change the date and got the change fee dropped. It then noticed the new date clashed with a dentist appointment on his calendar, called the dentist, moved the appointment and updated his calendar. He says this would otherwise have been more than an hour on hold. xAI's docs don't describe phone calls as a built-in feature, so calls like these need a separate calling service.
Poster's claim, not verified: He says the change fee was dropped. We have not verified this.
Copy this prompt
I'm booked on [AIRLINE] flight [FLIGHT NUMBER] on [DATE], booking code [CODE]. Check if the same trip is cheaper on another date between [DATES]. If it is, tell me the new price, any change fee and the fare difference before you contact the airline. Only change it after I say yes. Then check my calendar for anything the new dates clash with and suggest new times. Ask me before you call or message anyone.
Our own prompt, written from what the source describes. We haven't run it ourselves. Text in [BRACKETS] is what you replace.
Watch out for
- Ask for the new booking confirmation by email and check the date, time and name on it.
- Some cheap fares can't be changed at all. Check the fare rules before you count on a refund.
- Grok Bot needs a separate calling service to phone anyone, which usually costs extra.
