I live in a place where I have to fly to a nearby bigger airport to go anywhere outside my province. In other words, everything is a compromise on routing, layovers and cost. When I lived in a big city, it was just timing and cost that mattered.

Frequently it isn't that google flights on a phone doesn't find the same flight, its that it is much easier to figure out the tradeoffs with more screen real estate. E.g. I can see that a flight is cheaper, but it involves mixing airlines, and a terminal change that I probably can't trust on a tight schedule in winter.
