B. Good morning! Give me your passport, please!

A. Oh, sorry, maybe I forgot it! 

B. Please look it up again. 

A. Sorry, I left it at home. Is there any way to solve it? Help me, please!

B. OK, keep calm and wait a minute, please! Where are you flying to?

A. I am flying to Nha Trang. According to the schedule, the flight is going to depart in 1 hour.

B. Let me see. The next flight to Nha Trang will depart at 2 p.m. We have 5 seats left. Do you want to change the flight?

A. There is also no way better, to bother you to change flights for me. Thanks for your help.

B. OK, I'll change. Now, you have to re-register your ticket on the website, then go home to get your passport and return to the airport at least 1 hour before departure time.

A. Sure. I will be more careful. See you.
