Earlier quoted context omitted.
Disclaimer: I work at Kiwi.com. At https://kiwi.com we combine flights ourselves instead of just taking the combinations from the big guys, you should try it out with a few queries. Not being limited to airline agreements when connecting flights can really drive the price down or make obscure routes viable.
Who protects the consumer when weather or FAA traffic management makes you miss your connecting flight?
Apparently the rewrite of this dry wall of text is not live yet, so let me paraphrase:
You contact us and we book you the flight that gets you to your destination the earliest (if needed we pay for a taxi or bus or anything to get you to another airport if needed.)
