I work on the operator side of this business. Joel and his team (Christina, Simon, Kerry, and more) are all incredibly wonderful to work with. They are always responsive in a timely manner and deliver accurate information consistently. They bring a very positive attitude and outlook to this industry. Hopeful to book many more trips with them in the future.
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.
