A few weeks ago, I wrote a post about how I fly cheap on Spirit Airlines. There are other airlines that have similar cheaper flights and you can save a lot of money using them. Just keep in mind that there are trade-offs for the cheap fares such as no free food or beverages. I have a listed links to some of these airlines below.
Airlines change fares constantly, often multiple times a week. So when it comes to buying an airline ticket, timing is everything. To get the best deals you will need to check airfare sites often. I have about three sites that I check at least once a day. The price of a fare can change in a few seconds (many times the price will change while you are looking at the fare). I was looking at an airfare to Morocco which was listed at $167 and the price jumped to $850 after a few of minutes.
You can save hundreds of dollars by being flexible on your dates and destinations. Here is a random example I pulled up on Skyscanner
You can see how Skyscanner works from the photos above so below I posted a screenshot of Kayak Explore.
For this search I chose New York as my starting point. As you can see, there are blue flags all over the world. There are also blue dots which represent more prices which you can see as you zoom in on the map.
Here are some low cost airlines that you may want to check out. You can do a destinations search to see where they fly. Some of these companies will not show up on the three sites I mentioned above so they are worth checking out.
Keep in mind that these budget airlines are cheaper for a reason. Some will charge luggage fees and they usually don't serve any free snacks, meals, or drinks. Read the fine print before you book.
