Typically, booking a whole trip with different airlines would be risky. For example, let's say your first flight with JetBlue was delayed, and you missed your connecting flight with Norwegian Air. Because the airlines have no association with each other, Norwegian Air has no obligation to reschedule your flight for free, so you would just lose your money. Kiwi.com instead offers their own guarantee, which covers schedule changes, flight delays, and cancellations. As long as you contact Kiwi.com as soon as you're aware of the delay, they will provide you with an alternate connecting flight, or a full refund, at your discretion. We haven't used this guarantee ourselves, but it certainly sounds like an appealing way to take the risk out of a thrifty flight hack!

Here are some articles on travel hacking that can help:
Stopovers can range from a mere hour to even a full day (or more), so it's really up to you whether you would prefer paying less for your flights in exchange for doing some time at the connecting airport. The biggest issue is that time spent in airports eats into the "free" time you would otherwise enjoy at your final destination. If you do settle for a trip with a long layover, check into sights to see or activities to do near your layover airport. A 10-hour layover might provide the perfect opportunity to visit a famous landmark or explore a new city. To each, his own.
