Hello.

Hi. Hoe may I help you?
assistant
Myself Joshua Campbell. During holidays I love to spent some time with my parents in Los Angeles, so could you please book a ticket from PHL to LAX?
user
Sure, may I know your planned dates?
assistant
I would like to fly on 07/06 and return on 07/08.
user
I am sorry to say, no flights are available on your dates.
assistant
That's ok, no problem.
user
Thank you for approaching us.
