The travel industry has it's own unique language and we hope these suggestions will make your purchase a little easier. These companies operate under special contracts with the airlines to sell discounted airfare to travel agencies for resale to the general public. When you call an airline, the price they give to you is referred to as a published fare. These are not to be confused with discount fares which are generally sold by wholesalers or consolidators. That's exactly what they are.
Price equals convenience.
Discount tickets are usually the most restricted regarding changes or refunds. You are ultimately responsible for knowing what rules and restrictions apply to your purchase. Class of service refers to the price you pay for your ticket and boils down to what you get for your purchase. They pay for that convenience. There is no big secret about how to get a great price on international airfare.
