Hello.
Hello. How may I assist you at this moment?
Myself Sandra Phillips. Can you please book a flight ticket from SFO to LGA?
Sure, may I know your planned dates of travelling?
Sure, I need to travel on dates of 04/05 and 04/07.
Please wait a moment to check the flights availability.
Sure, take your time.
Sorry to inform you that, there are no flights moving to your region with your planned dates of travelling.
Oh! It is sad to hear. Anyway, I will go  with another agency this time.
