You should check that with the airline.Thank you.🤗
They won't make any problem on the airport if i get return ticket? Because the passport number will change as i get a new one.
I was curious, as I assumed it would not be an issue.
I found two answers from travel companies.
- We do not require your passport number to book a flight.
- It is possible that your airline does not allow passengers to alter or add passport numbers after booking the flight
- 2018 - Most airlines and third-party travel sites don't require you to input a passport number at the time of booking
It appears to vary..
