The CEO of a company I used to have dealing with, regularly flew transatlantic. Depending on the destination there were three methods.
1. The destination had facilities
2. They had to stop enroute at an airport with facilities, or
3. Arrangements could be made for the flight to be met, at increased cost, if the airfield wasn't too remote.
All details are sent ahead, the timetable of which is determined by the above (hours to days) so that pre-clearance is authorised to speed things along at the destination.
