I'd be happy to help with that. What day and time are you traveling? Do you need to arrive by a certain time?
I am looking for a train going from Cambridge to stansted airport. The train needs to leave on Monday after 11:45. No, just the closest time after 11:45 for 5 tickets please.

TR8699 leaves at 12:40 on Monday. Would you like to book a ticket?
