Information you need to make airfare comparison

Flight Comparison
Before you begin your airfare comparison, you need to know all of the following:
- Number of passengers
- City of departure and arrival
- Date of departure and return
- One-way or round-trip
- Non-stop or layover
- Budget
- Airlines servicing both cities
If you do not know the airlines servicing your cities, you can find out by visiting your local airport’s website or a travel site, which compares airfare. Since not all airlines service all airports, the price of flights will depend on which airlines fly to your airport.
Airfare comparison between airlines
Once you know which airlines service your airport, visit their websites to check for flights and airfare. Use your Internet browser to open one tab for each airline, so you can view the pages and close the tabs with the highest price or the worst service. When comparing flights, you must choose between price and convenience. Flights which are longer and have more stops are often cheaper than non-stop. If you have the time to spend on layovers or switching airplanes, you can save money at the expense of your time. If you must get to your destination directly, you need to be willing to spend more. When choosing between one-way and round-trip tickets, look carefully at the prices between airlines on one-way tickets. Historically, one-way tickets are more expensive than round-trip tickets. Early shoppers can find good deals on one-way tickets because they are booking far in advance. Occasionally, two one-way tickets on different airlines will be cheaper than a round-trip ticket. Last minute shoppers need to choose round-trip tickets to save the most.
Airfare comparison between travel websites
Travel websites offer the convenience of seeing many airlines’ ticket prices on one screen. Since travel websites offer discounted tickets, the prices are often cheaper than those listed directly on the airline’s official website. Aggregate comparison websites show the comparison between cheap ticket websites instead of the comparison between airlines. All airfare comparison sites will filter through posted ticket prices when you enter your information into their search engines. You will need the information from above (except the airlines) for all of these sites.

Air Fare Comparison
Some will ask you more detailed questions, such as choice of seating, number of tickets, your status as a reward member, preference for flight time and flexibility of dates. If you are flexible in your choices, you can often find less expensive flights. Off-peak flights, like those in the middle of the week or late in the evening, are less expensive than early morning and weekend flights. Flying to a remote airport, instead of a metropolitan center, can save you enough money to rent a car. Airlines discount these tickets to ensure all their planes fly at capacity. Search three or more travel websites before choosing the ticket, which is best for you. The first result in a search for airfare comparison websites may not always yield the lowest ticket price.
Whether you need to fly directly or can take the scenic route, airfare comparison ensures you are getting the right flight at the right price.
