Hi to all. I just got my double entry tourist visa by thai embassy in London My question is: can I book my return date 3 or 4 months later after the date of entry?

I'm well aware that I can get the extension in Thailand and use the second entry as well But I'm afraid that I could meet some problems during my departure at check in

Thanks

If you have a valid visa return fights are not required either at check-in or by Thai immigration.

You may book your flight without any need for concern
