There are many operators of airport shuttle services between Airports and Hotels around the world that operate on flexible routing and timing to offer a service that is both cheaper than a sole-occupancy taxi and also often more convenient that other forms of public transport. The requirement to carry luggage offers an added incentive to use such services over scheduled transport which will normally require a walk from the drop-off location to the final destination. Services from these operators are starting to spread from airports to railway stations and to other locations.
