Tips for Flying > Buy tickets

Should I buy my ticket online or through a travel agent?: Most travel agents also sell tickets for lowcost flights. A travel agent usually buys a large number of tickets at once, so that he may have some discount on the total price. But he adds a commission to the initial price. So if you buy your ticket through a travel agent you may pay a higher final price for your plane ticket. It's always a good idea to compare prices before buying your ticket. However, keep in mind that the cheapest tickets sell first, so don't waste too much time comparing!
