A Japanese Phrase for Asking to see a passport at check-in: "パスポートを拝見できますか？"

"パスポートを拝見できますか？" means "May I see your passport?" and it's the basic Japanese expression used for asking to see a passport at check-in. It's very handy at airports and when traveling. To answer, you can say something like "はい、どうぞ。" (Yes, here you are). You can keep the conversation going by reacting with something like "ありがとうございます。窓側と通路側、どちらがよろしいですか？" (Thank you. Would you prefer a window or an aisle seat?).
