Finally, be sure to check the rules on your ticket carefully, if you book on line. Be warned – the fare rules are not always clearly displayed, nor are they always easy to understand, as they are often written in airline jargon. If you book a cheap ticket on some of the major travel websites such as Expedia, Hotmail or Travelocity be especially sure to read the rules – your ticket may allow no changes or refund at all after purchase - the so-called “use it or lose it” rule. Some cheap fares booked on line may not allow upgrades, mileage accrual or standby options. None of this may matter to you – but if it does, be sure to read the small print or check with the website, if it isn’t clear. And it may sound obvious but make sure the name on your reservation is actually the passenger’s name and matches exactly the photo id that you or they will be taking on the trip. If you log in under your name to a particular site, the site may assume it is you that is traveling, and input your name, even if you are booking for someone else.
