"I can’t go. I have to stay around and fight off the Crazed Radical Left Lunatics," Trump says
In the midst of a considerable amount of legal woes, Trump appears to be spending his Sunday focusing on what's most important to him presently . . . golf.

I doubt they need to physically take his passport. I'm pretty sure that can be revoked by the DoS at any time. Also with how public this is, I doubt any airport would even allow Trump onto the premises at all, for fear of what may happen if they somehow let him escape.
He does have a private jet. It’s not like Trump is going up to the ticket counter at American Airlines and asking for a ticket, then proceeding to go through TSA for an x-ray or a pat down.
That is also true, but he would still have to file a flight plan. Otherwise those pilots might as well get asylum too, they would never fly again in the US if they took off without filing an FAA flight plan.
