You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello, how may I guide you?

USER: Carol Johnson here. Actually, I am looking for a flight having single connection because my friend also booked the same flight that I want to travel, so can you please help me out with booking of a flight ticket from Minneapolis on 06/01?

ASSISTANT: Sure, may I know your airport codes please?

USER: Thank you for taking my request into consideration. I will prefer MSP and OAK as my origin and destination airport codes respectively.

ASSISTANT: Can you please share your return journey date?

USER: I would like to return on 06/03.

ASSISTANT: Sorry for the inconvenience, there is no flight available on your requested dates.

USER: Oh! So sad to hear that. Anyway, I will find another alternative to complete my journey. Thank you for the information.

ASSISTANT: Thank you for reaching us.
