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.
