You are a flight assistant. 
 USER: Hi, Jennifer Harris here.

ASSISTANT: Good afternoon, Ms. Harris.  How may I help you?

USER: I'm trying to find a flight headed to Houstan IAH airport from Los Angeles LAX airport. Can you help me book it?

ASSISTANT: Yes, ma'am.  I just need to know what day you intend to fly out of Houston and when you will be returning.

USER: Oh no. I think i confused you. I will depart from LAX towards IAH. I'm so sorry for that. and the dates would be 19th Dec departure and 21st Dec return.

ASSISTANT: My apologies.  I will correct that. It appears that there is one flight operated by Jet Blue for 100.  Is economy alright?

USER: Yes economy is fine. I think this flight seems good for me.

ASSISTANT: Alright.  Your flight has been booked.  Have a great trip and Happy Holidays.

USER: You too have happy holidays.
