On my recent tip to New York (NY), I jumped in a cab / taxi from JFK to Manhattan and wondered how much I should tip the cab / taxi driver. I asked around, asked the cabbie and found out that the usual tip percentage is about what you do with restaurants. If the guy packs and unpacks your bags, takes you on the quickest route, avoids traffic, etc give him 20-25%. If it's a quick trip with little service involved, a 15% tip will do. I hope this helps and visit www.Aarons2Cents.com for more info.
