Give your dates a little room.
Begin with the length of trip you want, then decide how much the departure date can move. A flexible window gives you more options to compare without changing what the trip is for.
Compare the total cost, including the extra night, airport transfer, and baggage you need. A lower fare is only useful when the rest of the journey still makes sense.
Keep a short list of routes and the conditions that would make you choose each one. When a verified fare arrives, the decision will be easier.
