When looking for commercial airline tickets, although some carriers offer a better product than others, the difference in quality amongst carriers is far less than that of private jet options. Simply put, there are exponentially more variables in private jet flights which dictate value than there are for commercial flights. Because of this, it is much more difficult to properly compare two private jet quotes from two different providers than you may think.
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.
