Make Ryanair and easyJet your best friends.

     If you have ever traveled within Europe, you have surely heard of, or even utilized, one of these blessings from above. If not, then let me introduce you: reader, meet the two cheapest airlines in the world: Ryanair and easyJet!!

     So now that you're acquainted, let me tell you a little about these two incredibly cheap airlines.
Ryanair is based in Dublin, while easyJet is based in London. Fares have been known to drop as low as £3.99 (about $7USD) one way. While this is very rare, it is not uncommon to see one way flight from Ireland to London, London to Berlin, or Paris to Madrid for under £15.99 one way.
     While the rule of thumb for backpacking is always to pack light, only what you can carry on your back, this goes even more so when flying these airlines, as it's the baggage fees that can rack up the debt on your credit card. Your first checked back will run you about £16, but the upside is that they aren't too strict about the size of your carry on, so just don't check your bags, and you're good to go.
     The best way to find these cheap flights is to sign up for email alerts. When you register for these alerts, you have the option to stating which flights you are most interested, so you will be alerted whenever your flights go on sale. These alerts make it possible to fund the inter-Europe airfare of your seven country tour of Europe after only one day of work making the California minimum wage. Pretty nifty, I'd say!
