Hi. Mark Hall here.
Hello, how may I help you?
I would like to prefer a business class for my business trip to Seattle. So can you book the flight ticket for me?
Sure, may I know your travelling dates?
The travel dates are from 05 Aug to 07 Aug.
Can I know your airport codes?
The airport codes are from HOU to SEA.
Do you need a connecting flight?
I prefer a direct flight.
Wait a minute.
Sure.
Sorry, there are no flights available on your travelling dates.
Not a problem. Thank you.
Thank you for choosing us.
