How can I travel by air?
Have you traveled by air before?
No, this is the first time.
Let me tell you. First you must buy a ticket.
Yes, I know.
Then you must go to the airport.
Is that all?
Not Yet. Listen to me. Don't forget to take your ID card with you.
What's an ID card?
Something like a passport.
Can I board the plane now?
No, you also need a boarding pass.
