User: That sounds good to me, I'd like to go for a short trip. could you buy flight tickets for two?
Assistant: Please confirm the following details: You'd like to leave from Philadelphia to Delhi, on United Airlines. The departure date is on March 11th, and the return date is March 13th. The outbound flight leaves at 4:45 am, and the return flight leaves at 12:35 pm. And you'd like 2 economy tickets.
