On Kayak, register your email address and select "Show flexible dates"; search for "Southwest Shortcut" to see Southwest's tool and "JetBlue best fare finder" to find JetBlue's.
You Might Not Need Travel Insurance
Your credit card might already have free, built-in travel insurance up to $5000 per trip for the most common reasons people use insurance, which include canceling before or during a trip due to illness or injury, and lost or delayed baggage. The Chase Sapphire card, United Explorer Card, and some Citibank Aadvantage cards offer the best protection.

After you pay for an airfare or a hotel, the price may have dropped, but most people never check. You can get either cash or a credit for future travel if you know how. Yapta.com is useful for airline tickets, Tingo.com for hotel rates.
