Flymble is a flight financing service and app. It allows its users to pay back the cost of a flight, with some interest, over a series of months. The number of months can range from 2 all the way up to 10. Though Flymble does nothing to assuage the other costs of a vacation, it can be useful in a pinch when you need to get somewhere and can afford a slightly larger premium in the long term. The app itself is well-designed and provides most of the needed information.
