Even just a little bit of flexibility can save you money. One EU vacation I was able to save $500/ticket by leaving early in the morning and flying to the hub airport, paying the $50pp for the nice airport lounge, and working all day (those lounges are built for business travelers are a lot like co-working spaces) from there. I finished working, had another 'free' snack, got on the plane to the EU, and started my vacation.
