Check out the International Student Travel Confederation (ISTC; www.istc.org) website for comprehensive travel-services information and details on how to get an International Student Identity Card (ISIC), which qualifies students for substantial savings on rail passes, plane tickets, entrance fees, and more. It also provides students with basic health and life insurance and a 24-hour helpline. The card is valid for a maximum of 18 months. You can apply for the card online or in person at STA Travel (tel. 800/781-4040 in North America; tel. 134-782 in Australia; tel. 0800/819-9339 in the U.K.; www.statravel.com), the biggest student travel agency in the world; check out the website to locate STA Travel offices worldwide.
If you're no longer a student but are still under 26, you can get an International Youth Travel Card (IYTC) from the same people, which entitle you to some discounts. Travel CUTS (tel. 800/667-2887; www.travelcuts.com) offers similar services for both Canadians and U.S. residents. Irish students may prefer to turn to USIT (tel. 01/602-1906; www.usit.ie), an Ireland-based specialist in student, youth, and independent travel.
