A There are many ways to do a flight search online. You can search through all the discount sites, or search a service which lists all flights in one place. You really have to pay attention to what comes up though, as sometimes savings are not worth what they might seem. If you cannot choose your own days, and you cannot be flexible about when you leave, a cheaper ticket is not going to do you much good. For example, if your flight search gives you a better deal if you can leave a day later than you planned to and you are flexible enough to take advantage of the option, you just found a great deal.
Getting a better deal on airline tickets may involve taking a flight with more stopovers than a higher priced one. There are times when a flight is one way with one stop, or no stops, but a less expensive version might stop in three different cities along the way. Most do not like that many stopovers because they feel that ups the chances of lost luggage and takes too long. However, if you do not mind that too much, and you find a cheaper ticket through a flight search with many stops, take it if the savings seem to be worth the extra hassle.
Remember that your flight search will yield different results depend on when you search. Searching as early as possible is going to find you the very best airline deals to choose from. If you wait until a week before you have to go, your flight search is going to yield very few deals. It also depends on the day of the week you choose to search. Some say that Wednesday night is when many cheaper flight seats open up, so you may want to look then, or first thing on Thursday morning to see what type of deals you can find. Spending a little time searching for great deals can save you anywhere from fifty dollars to two hundred fifty dollars.
