Hi there! I'm hoping you can help me out. I recently spoke with one of your customer support representatives on the phone, and they told me that a service agent would be able to help me cancel a reservation. I'd like to go ahead and cancel my trip from Philadelphia to LaGuardia.

agent

I'd be happy to help you cancel your reservation. To get started, I'll need your user ID to access your account information. Could you please provide your user ID?

user

Sure, my user ID is raj_sanchez_7340.

Thank you. I've located your reservation Q69X3R for the round trip from Philadelphia (PHL) to LaGuardia (LGA). Before I proceed, could you please provide the reason for cancellation? (e.g., change of plan, airline cancelled flight, or other reasons)

user

It's just a change of plans on my end.

The reservation does not meet policy criteria for automated cancellation (not business class, no travel insurance, and not cancelled by the airline).
