Most people plan a trip and then go looking for a flight. We do it backwards. We watch the flights, and when one blinks, we plan the trip around it. It is a less romantic way to live and a much cheaper one.
Right now the flights are blinking. Caribbean airfare has dropped to its lowest in years, and it goes both ways. Flights to Puerto Rico are showing up around $119 round trip, our own San Juan to mainland routes are soft, and fares across the region are sitting in the low $300s while the rest of summer travel got more expensive. This is not normal, which is exactly why it is worth talking about the boring habit that lets us actually use a window like this instead of noticing it three days after it closes.
Here is the whole unglamorous method.
Pick your routes and let the robots watch them
We do not stare at flight prices all day. We are not that disciplined and neither are you. Instead we set fare alerts on the specific routes we would actually fly. We live in Puerto Rico, so for us that is San Juan to LA, San Diego, Orlando, New York, and Boston. Then we forget about them until an email says the price dropped. Google Flights does this for free. So do a handful of other tools. You pick the route, you pick "track prices," you go live your life. The robot watches the fare so you do not have to.
The trick is setting alerts before you have a trip in mind, not after. By the time you have decided you "should" go somewhere, you have already talked yourself into paying whatever it costs that week.
Decide your yes price in advance
This is the step that separates people who catch deals from people who admire them. Before the deal ever shows up, decide the number that makes you go. For us, a round trip under $250 is an automatic yes, no meeting required.
Deciding in advance matters because good fares do not wait for you to think it over. They are gone in a day or two. If you have to hold a family summit every time a deal lands, you will miss all of them. If you already know your number, the decision is made before the email arrives. You are just confirming it.
Stay flexible on the dates, rigid on the price
The cheapest fares almost never fall on the dates you would have picked. That is fine. We keep the dates loose and the budget firm, instead of the other way around. A Tuesday departure you did not plan on is a small price for a fare that is half what everyone else paid.
Flexibility is the discount.
Be ready to move
When the fare blinks, we book that day. Not next week, after we have compared it against a hypothetically better one that may never come. The version of this that works is not "find the perfect deal." It is "recognize a good one and act before it evaporates." We would rather book a great fare in an hour than lose it while hunting for a perfect one.
The point
We are not lucky and we are not rich. We just decided a long time ago that the flight comes first and the plans come second, and we set up a system so that a cheap fare finds us instead of us chasing an expensive one. It is a boring habit that produces a very un-boring life.
Caribbean fares are genuinely low right now, so if you have been meaning to set those alerts, this is a good afternoon to do it. If the low fares have you itching to actually go somewhere warm with people who get it, we happen to be taking a group to the Dominican Republic this October. Come with us. No fare-watching required for that one. We already did it for you.
