Collect airline travel information online from air travel portals that offer a number of resources Flight travel information portals are a great place to begin your research to find flight travel online because they give you a wide listing of resources to choose from.

I recommend:  Airport Explorer gives a listing of the best sites offering low-priced airfare for domestic and international flights. This flight travel portal also offers great flight travel searching tips.

Gather flight travel information online from specific online airline reservation providers Find airline travel online from specific websites. The advent of Internet travel websites has made it even easier to search for flight information online. These online travel providers allow you to gather air travel information using specific search criteria. Many online travel websites also allow for hotel selections, rental cars and other travel needs.

I recommend:  Build your trip by using Expedia, which allows you to search a flight by typing in search criteria such as dates, departure and arrival times, and the number of passengers. There are also options to book a flight together with a hotel or rental car to save money. Travelocity also allows you to provide flight information to search for a specific flight, offering $240 in savings for booking a flight and hotel together. Orbitz provides the same type of flight search system as Expedia and Travelocity with a variety of vacation packages. If you book a flight through Orbitz, you will receive an automatic cash refund if another customer books the same flight at a lower price.

Book an online airline reservation after completely knowing the online reservation process Before booking your flight, ensure you've researched all of your flight options and how to reserve your flight online. Do price comparisons between an airline's website and an Internet travel site before booking a flight. The actual airline may offer the fare at a less expensive rate when reserving online than on an Internet travel site. In some instances, the airfare may be the same price. Most airlines have similar online reservation systems.

I recommend:  United Airlines offers a variety of low fare options. If flying on United, go to its website and select the Book Travel tab. Select and type in all search criteria, then follow the prompts for each page to book your flight. Delta Airlines also offers low-priced airfare deals and has a similar flight booking interface.
