Hidden textI'm sorry for the confusion, but as of my last training cut-off in September 2021, ChatGPT doesn't have the ability to book flights, make reservations, or perform any actions in the physical world. It can't interact with other systems, databases, or services on the internet. Its primary function is to provide information and engage in text-based conversations based on the data it was trained on. If you've interacted with a system that booked a flight for you, it's likely that you were using a more specialized AI system or a service with integrated booking capabilities. Those types of services are designed to interact with external systems and carry out transactions. If you have more questions or need assistance with anything else, feel free to ask!
