Yes, let's go ahead and book that.
My apologies, I believe there was an error in the database lookup. TR2045 is not available but TR3353 arrives at 17:51 on Sunday. Shall we book that instead?
Yes, please give me travel time and departure time, please.
Certainly. The departure time is 17:00 and the travel time is 51 minutes. I have booked your ticket. The reference number is BJJ3GXMX. Can I help with anything else?
