Often the cheapest way to get to and from the airport, shuttle vans often offer a cost effective alternative to taking a taxi. Typically, airport shuttle services use large passenger vans and provide pickup service from your home, hotel, or office to (or from) the airport. You share the ride, and hence much of the cost, with fellow travelers in your immediate area.

• Shared ride shuttles: if you’re taking bags and the driver helps you loading/unloading them, its appropriate to give the driver a few bucks for his/her efforts.
  
• Sedans/limos: the most appropriate form of tipping is a percentage of the fare, usually around 15%. Drivers derive much of their income from tips and usually deserve a gratuity if their service was satisfactory.
