We prefer to finalize our itinerary, plane and crew at least a week in advance. We did not get things completely final until the day of the actual flight. Secondly, we prefer to pay post-flight rather than pre-flight. You were able to make an exception in our case which was appreciated. Lastly, the quality of the catering service from STT was atrocious. It was inedible.
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.
