ASSISTANT: Please be on hold for a moment to record all your details in my portal and I will get back to you, if there is any flight obtained in our portal on your details.

USER: Sure, I can wait for your response and please provide me an enhanced flight for my journey.

ASSISTANT: Thank you for your patience, I have checked for the flight availability with your details but there is no flight moving towards your region due to sold out of ticket.

USER: It's very sad to hear from your end but the work is important for me, can you please check is there any special flight available on my preferable travel dates?

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

USER: Ok, no problem with that one. I can ask one of my friend to help me to reach my destination. Thank you so much for your immediate response.
