Since retiring early, we’ve been traveling a lot more, but it sure gets expensive. Naturally, we’d like to keep costs as low as possible without giving up too much convenience or comfort. I’ve looked into popular travel hacks such as credit card point churning and searching for alternative airports. But a lot of them remind me of extreme couponing: They might save us money, but they also sound like a lot of work. And that's not exactly what I had in mind when I retired early.
