When applying for the visa non-o family they ask for a flight nr. what if we would change the date or the airliner changes our flight which would not be for the 1st time?

Hello,

I am from France,

For the visa, it is required to put a flight number. I am not sure yet which flight I want to take because I don't know how long the system will take to manage my file.

Can the flight number I put on the 60 days visa application be different than the one I will actually take and different of the one for the Thai Pass ?

Thank you all
