Task-oriented dialogue about: train

Hi, I'm looking for a train departing from Stansted Airport. I'd like it to arrive at the destination by 9:15.
Sure! It looks like we have four morning trains daily the are early enough for you. What day are you planning to travel?
I need to leave on Thursday.
We only have trains going to Cambridge then, is that your destination?
Yes, I want to go to cambridge. Can you make a booking for 7 people and give me the reference number?
I have train TR9084 that leaves the airport at 08:24 and gets to Cambridge at 08:52. Would that train work for you?
Yes, that's great can I get 7 tickets please?
Alright, your 7 tickets for the TR9084 train has been purchased for 70.7 GBP. The reference number is CVJZNB86 . Is there anything else I can do for you?
I think that's all I needed. Thanks. Have a good night!
