Lesson

After an agent rebooks a flight, check every passenger

The poster planned a whole family trip with several agents, mostly Meta Muse, plus ChatGPT Dots and a little Grok Bot. He liked Muse best for planning. The day before the flight he needed a later departure: one agent worked out what cancelling would cost, while others chatted with airline support. After an hour on hold himself, another agent (Instinct, which we don't cover) got them rebooked. But at check-in the baby's ticket was missing from the new flight, and on the way back the baby was double booked. Nobody at the counter could explain it, and he couldn't see what the agents had said to support.

The lesson: After an agent changes a booking, check every passenger on the airline's site and keep the transcript.

Copy this prompt

Change my flight [BOOKING REFERENCE] on [AIRLINE] to a later departure on [DATE]. Passengers: [LIST EVERY PASSENGER, INCLUDING ANY LAP INFANT]. Before you confirm, tell me the fare difference and any fee, and wait for my OK. After the change, send me the full chat or call transcript with the airline and the new confirmation, and check that every passenger, including the baby, is on the new booking.

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

  • Lap infants and companion tickets are easy to lose in a change. Check the new booking on the airline's site yourself.
  • Ask the agent for the full transcript of what it told support, not just a summary.
