Percakapan Bahasa Inggris: Membeli tiket pesawat terbang

Setelah pada pernyataan sebelumnya saya menyatakan bahwa saya tidak akan posting karena mau fokus, mending di pake buat belajar aja ya, jadi untuk kali ini dan seterusnya saya akan tulis-tulis tentang tugas saya di sekolah, kecuali yang diary :D

clerk: Next please. Hello. How can I help you?
Larry: I'd like to buy a ticket to New York.
clerk: Would you like one way or round trip?
Larry: Round trip.
clerk:When will you be leaving?
Larry: When does the next plane leave?
clerk: In about 2 hours.
Larry: I'd like a ticket for that flight please.
clerk: First class or coach?
Larry: Coach.
clerk: OK, let me check availability. I'm sorry. Tickets for that flight are sold out.
Larry: How about the one after that?
clerk : Let me see. Yes, that one still has seats available. Would you like me to reserve a seat for you?
Larry: Yes, please.
clerk: That'll be 120 dollars.
Larry: OK.
clerk: Thank you, here's your change.
