These are the best links to find travel specials on the internet. It's best to compare as many specials as you can before you buy.
Be very aware of hidden costs because there might be taxes and other fees not previously disclosed in the original price.
Also read the contracts of any travel disclosures about protecting yourself and your belongings. Also be sure to check your
airlines refund policy (contract of carriage) and and know your rights on flight changes, delays and cancellations. Sign up for
airline "alerts" for quick notification of delays or cancellations. Know before your flight what other airlines are flying to your destination,
 so incase of cancellations you can call them or ask gate agents for availability then go directly to their terminal.
