I’ve used Kayak a bunch too, and it’s pretty solid for flexible dates—really handy when you’re not locked into specific travel days. Google Flights is another one to check out. It’s quick, and I like how you can mess around with different dates and airports to see where you can save. It’s super easy to spot trends, especially if you’re not rushing to book.
For international flights, I’ve also found deals on
cheap business class tickets. If you’re up for some extra comfort without blowing the budget, it’s worth a look.
