Planning an international trip and wondering if a passport is required to book your flight? The short answer is, No, you don’t need a passport to book most international flights -but you will need one to travel.
Do I need a passport to book a flight?
Yes, most airlines and booking platforms (including Trip.com) let you book international flights without providing a passport number upfront. All you need is:
- Your full legal name (matching exactly what’s on your passport, including spelling, order of first/last name, and punctuation)
- Date of birth
- Contact information
This means you can secure flights while waiting for a new passport or renewing an expired one. However, there are key caveats:
- Some airlines (e.g., select Middle Eastern or Asian carriers) may require passport details at booking—always check the airline’s policy before purchasing.
- Most airlines will ask you to submit your passport number 72 hours before departure (via their website or app) to finalize your booking.

As mentioned above, you can book a flight without a passport! Most airlines and online booking platforms don’t require a passport number at the booking stage—you only need to provide basic personal information to complete your purchase.
If you decide to book your flight first and take care of your passport later, make sure the romanized spelling of your name on the ticket matches exactly what will appear on your future passport—including the order of your last and first names and any punctuation. If there’s a mismatch, you may have to pay extra to change your ticket details, or even rebook.
Also, while you might not need to provide passport information when booking, many airlines require travelers to submit complete passport details 72 hours before departure. To keep your trip on track, it’s best to get your passport sorted early so processing times don’t delay your planned itinerary.

You can technically book a flight with an expired passport (since booking doesn’t require valid passport details), but you will not be allowed to board—and no country will let you enter with an expired passport.
Additionally, most countries enforce the 6-month passport validity rule: Your passport must be valid for at least 6 months beyond your planned return date. Some destinations (e.g., Schengen Area, Thailand, Japan) strictly enforce this—airlines will check at boarding, and you’ll be denied if your passport doesn’t meet the requirement.
Pro tip: If your passport is expired or has less than 6 months validity left, renew it first before booking. If you already booked, renew immediately and update your passport number with the airline.

Do I need a Passport to Book an International Flight | Practical Tips to Avoid Issues
- Name consistency is beyond doubt: Use the same name (spelling, order, punctuation) as your passport. If you make a reservation before obtaining your passport, please use the name on your ID card (it should match your passport application).
- Update your passport information timely: Once you have your passport, log in to your booking (on Trip.com or the airline's website) and add your passport number. Don't wait until the last minute- delays in updates may cause check-in issues.
- Check the specific rules of the destination: Some countries (for example, China, India) require additional documents (visa, electronic visa) and your passport number. Take these into account in your schedule.
- Expedited processing in emergency: If your travel period is less than 4 weeks, please use the expedited passport service (with a charge) to ensure that you obtain valid travel documents in a timely manner.

Passport Application Process
If you’ve never applied for a passport before, there are usually two ways to do it: go in person or use an authorized agent to handle it for you.
1. Required Documents (Global Standard)
- Valid national ID (driver’s license, national ID card)
- 2 recent passport photos (white background, 2x2 inches/35x45mm, taken within 6 months)
- For renewal: Original expired/expiring passport
- For replacement (lost/stolen): Police report + ID proof
2. Application Methods
- In-person: Visit your country’s consulate, immigration office, or authorized center (check official websites for locations).
- Online: Many countries (U.S., UK, Canada) offer online renewal for eligible applicants (no new photos needed if appearance hasn’t changed).
- Agent/service: Use licensed travel platforms (like Trip.com) for document pickup/mail-in services (saves time, no long lines).
3. Processing Times
- Standard: 1–4 weeks (varies by country; e.g., U.S.: 6–8 weeks; EU: 2–3 weeks)
- Expedited: 3–10 business days (extra fee applies)
How to Renew Passport
If you realize that your passport is about to expire or has already expired, it is best to start the renewal process as soon as possible. According to the regulations, as long as the validity period of your passport is less than one year, you can apply for renewal, which means you can renew your passport before its expiration.
The process of renewing your passport is similar to applying for one for the first time. You need to bring your original ID card, two color photos that meet the requirements (white-background photos taken within the last six months), and your original passport. If your passport has been lost, you must first report it lost and then apply for a replacement.
You can directly apply for a renewal at the Bureau of Consular Affairs of the Ministry of Foreign Affairs or any service office. Standard processing takes approximately 10 working days. If you are in a hurry, you can choose the expedited service, but an extra charge will apply.
After the update is completed, your new passport will have a brand new number and validity period. If you have already booked a flight or applied for a visa, please do not forget to update your passport number in the booking record or the electronic visa system to avoid information mismatch when boarding or entering or leaving the country.
