For as long as most of us can remember, one piece of travel advice has been a staple in every single blog, newsletter, and community: book your flight on a Tuesday and you will get the best deal.
It sounds like it makes sense. Airlines update their prices at the start of each week, so when demand falls in the middle of the week, prices fall with it. For a long time actually, that pattern really existed, but it does not anymore.
Traveler behavior did not change, but airline technology did.
Airfaire pricing is no longer driven by preset schedules or weekly updates. Today, most airlines rely on AI systems that adjust prices continuously based on demand, inventory, competitions, seasonal trends, and booking behavior from individual users. Prices aren’t reviewed once a week, they are constantly monitored and could change dozens of times in a single hour.
One of these AI-driven systems is Fetcherr, which helps airlines and hotels squeeze the most amount of revenue out of every seat or room booked. When demand spikes, prices rise, and vice versa. There is no longer a weekly calendar that you can rely on to book comfortably knowing you got a good deal.
The truth in 2026 is that the bigger problem has become not when people book, but what happens after they do. Most travelers still treat booking as a finish line. Once the confirmation email arrives, they assume the price is locked and move on to planning the rest of the trip. But in today’s pricing environment, the ticket price will continue to fluctuate long after purchase.
If demand drops, if an airline needs to fill seats, or if a competitor launches a sale, fares can and will go down. This happens quietly, without notifications or refunds unless the traveler actively monitors the price and rebooks it.
That means that most travelers overpay and never realize it, and you probably did this on your last trip without having any idea it was happening.
This is the part that outdated advice like “book on Tuesday” completely ignores. Even if you time your purchase well, there is no guarantee the price will not drop afterward. And nearly no one knows to or has the time to sit around refreshing their bookings every day to check.
As airline pricing becomes more automated, the smartest strategy is no longer about finding the perfect moment to click purchase, it is now about protecting yourself after you do.
That is where tools like Repriced.ai come in.
Instead of trying to predict when prices will fall, Repriced is an AI that monitors your flights and hotels 24/7 after you have already booked. You connect your email, and it automatically tracks your reservations and checks for price drops. If the same flight or hotel becomes cheaper, they initiate the repricing process and recover the difference for you. That is free cash back without lifting a finger.
Repriced is free to sign up for, and users only pay when actual savings are found. In an industry that now runs on dynamic pricing, protecting yourself after booking is becoming less of a luxury and more of a necessity, and now it couldn’t be easier to protect yourself.
Airlines use AI to adjust fares continuously, and travelers who rely on timing tricks from the early 2000s are playing a game that has already changed. Nowadays, the best way to beat AI is by using AI to your advantage too.
