The analogy would have worked better if you used a Fedex jet instead of a BA one. That said, I don't think the latency of transferring large data is the best selling point for Cloudflare, especially since the acks are asynchronous and good load balancers perform quite well over long latency links. A better selling point for distributed delivery is the round trip when you deal with multiple transactions, for example requesting a web page and then the included objects, or submitting data and waiting for a response.
