Flight was for an elderly person and the tail number was provided a long time before the flight and I made sure the person flying had all the info written down by someone who could hear and got everything correct. Flyer had that until day before when tail number changed. I had to find someone who could hear me well and right down the correct info for the person traveling so he got it straight in his head and for driver.
Of course, the cheapest way to fly privately is to have a friend who invites you on their flight. Then there are the semi-private charters like JetSmarter, JetSuiteX and JetClass where you can buy a seat on a scheduled private jet and corporate shuttle flight sharing it with strangers, much like if you were on a commercial airline. You can buy tickets on these flights for under $200 and you do avoid those crowded main airport terminals. However, if you want to have the real deal experience, chartering your own private jet, you are looking at something between $5,000 and up to $20,000 per hour depending on the size of aircraft and routing.
You will be told how much the hold can take on your chosen aircraft and can upgrade if you feel more space is needed. This will generally be far more than that of a commercial airline. You may also need to upgrade if carrying things like golf clubs and skis. If travelling with a gun, you will need to provide a license and the gun and ammunition must be kept separate. It is then at the captain’s discretion whether it can be on board.
