Booking flight on thaiairways.com w/ wrong passport number – ok?

[henrik2000]

Hello, here's me trouble:

• February 2025 – already NOW want to book cheap one-way flight EU – BKK on Thaiairways.com for next November
• September 2025 – my passport expires, and i'd like a new passport only in September
• November 2025 – the flight takes off

When booking online, Thaiairways.com asks your passport number and passport expiry date. You can't leave these fields empty. But you can fill in a bogus passport number and a bogus expiry date and click through till payment, I tried that.

So could I make my online booking with bogus passport number and bogus passport expiry date?

(NB, this NOT about visa application and NOT about online check-in. On those occasions I would present the correct info from the new passport of course. Also I don't need a visa beforehand.)

Notes:

• It is not totally unlikely to have a changed passport number after booking online. One may have lost one's passport and replaced it.
• Getting a THAI flight on booking.com, they don't ask for your passport number and it is 2% cheaper. BUT I hear it's better to book straight with THAI in case of complications (my western home airport has a lot of strikes, and I want to book sports luggage on top of the regular luggage, doable only after having a confirmed booking).

Just get a new passport now .

You may save six months passport validity, but they may lose your flight .

Don't go putting in fake passport numbers

Call THAI and tell them your situation and see what they say. If THAI can't offer a solution, get a new passport now.

 

Don't put any bogus information into their reservation system.

I would just use a third party website to book this.  Many don't require you to enter a passport.  Trip.com, Expedia, Priceline.  There are many others.

Priceline always asks for my passport number.

That's interesting, because booking.com (a Priceline brand) does not ask the passport number when booking a Thai flight on my route, i tried it (just before the Payment threshold).

You should be able to change it online. When I renewed my passport in the UK two years back I had the same problem but with Qatar Airways. Was able to change passport details online for the return flight. Failing that surely if you presented old and new passport at check in they would understand.
