I am going to Taiwan in a few months, and due to a change of plans, I will be staying an extra week while the others I am supposed to go home with continue.
I am unable to cancel my original ticket, but I am happy to leave others an extra seat available to them.
My question is, if I go through security and up to the door with them, would I have problems getting out afterwards? I would tell them at the door not to call me or wait because I will not be going up.
And when I enter the country, I guess I should show immigrants my second ticket instead?
