Airport commutes are typically very busy and if you are new to the city you are less likely to have an acute and on-ground real-time understanding of the traffic situation at a given point of the day. This may result in you miscalculating your commute time and you may end up missing your flight. This is why airport commutes are reliable only when you take a cab. Cabs understand the roads and the on-ground traffic conditions. They can navigate through the busy crowded and traffic-intense roads easily and can even find the shortest routes to the location. You do not have to worry about anything. All you have to do is relax and sit back and enjoy the ride. If it is a business flight you can prepare yourself for that.
