It may seem hard to find airfare deals, but they are definitely out there. Here are few ways to find very cheap airfare.
If you know someone in your family that works for an airline company, chances are they can get you some very cheap flights, maybe even free. They can pay a fraction what the public has to pay for when buying airline tickets. It is different for every airline company and depending on what they do for that airline. But it deffinitely doesn't hurt to ask, especailly if you are traveling very far, they could save you hundreds of dollars.
Sign up for airfare deals online. Many airline companies will have great deals for the public listed on there websites, so be sure to check those out. Also many of the airlines have newsletters or something similar that you can sign up with your email. If that is the case, definitely sign up because they may send out promotional codes or special discounts to members.
If you travel very often you may want to try using frequent flyer miles. Frequent flyer miles are accumulated from using a the same airline company when flying. After you have gotten enough points you can buy an airline ticket for a very discounted price. Or, if you have enough points, you might can even get a free flight. Some credit cards will also give you points for using their credit card. So if you are a big spender or a big flyer, those are two things to definitely look into.
