How to Use Passport Details While Booking Flights Online

Booking an international flight today is easier than ever—but one small mistake in your passport details can lead to denied boarding, extra charges, or even visa issues.

Whether you’re a first-time traveler or a frequent flyer, understanding how to correctly enter passport details during online booking is essential.

This guide walks you through everything—step-by-step—along with expert tips to avoid costly errors.

📘 Why Passport Details Are Required in Flight Booking

For international travel, airlines require passport information to:

• Verify your identity
• Comply with immigration and security regulations
• Match your ticket with official travel documents
• Pre-submit traveler data to destination countries (API system)

Without accurate passport details, your booking may become invalid.

🧾 What Passport Details Are Required?

When booking a flight online, you’ll typically need to enter the following:

1. Full Name (Exactly as in Passport)

• Must match letter-by-letter
• Includes first name, middle name (if applicable), and surname

👉 Example:
If your passport says John Smith, you must enter the same format.

2. Passport Number

• A unique alphanumeric code
• Found on the passport’s main page

⚠️ Double-check carefully—this is the most critical field.

3. Passport Expiry Date

• Must be valid for at least 6 months beyond your travel date (for most countries)

4. Passport Issuing Country

• Country that issued your passport (e.g., India, UAE, UK)

5. Date of Birth & Gender

• Must match exactly with passport records

6. Nationality

• Usually same as issuing country, but not always

Incorrect passport details can result in:
