Choose to fly on airlines and through airports that embrace environmentally friendly initiatives. Some of the largest airports are aggressively implementing energy- and cost-saving green measures. Check airport websites for outlines of their green policies.
Elect to receive your ticket electronically rather than requesting a paper ticket for travel.
Pack lighter and smaller amounts of luggage which cuts back on fuel usage for the aircraft. Every passenger who cuts back on weight lessens fuel consumption.
Use a recycled plastic zip-lock bag for your toiletries and pack an extra one for the trip home in case your bottles leak.
Wash your hands often while traveling to cut down on germs. Air dry your hands or use an electric hand dryer instead of individual paper towels. Simple practices contribute to going green.
Read your favorite books or magazines on an electronic reader rather than buying paper products. The Amazon Kindle and the Barnes and Noble Nook are two popular options.
Carry a refillable water bottle that you can empty when going through security and refill from the tap.
Take advantage of in-airport and on-board recycling programs such as disposing of plastics, papers and glass in the appropriate receptacles.
