Finding a genuinely cheap flight in 2026 still comes down to two things: being flexible about where you go, and moving fast when a fare drops. A new AI assistant called Pax, launched by Canadian booking platform FlightHub over the summer, is designed to handle both — and it's worth understanding how it works before you dismiss it as another gimmicky chatbot.
The setup is deliberately simple. You hand over your email address and home city, and Pax sends a single weekly email listing the best fares from a range of airlines. Each deal comes with the price, the travel date range, and — the most useful bit — a comparison showing how far below the average fare that price actually is. That last feature cuts through the classic booking trap of staring at a fare and wondering whether it's genuinely good or just less bad than usual.
The weekly rhythm matters more than it sounds. One of the reasons deal-hunting fails for most people is alert fatigue: daily or hourly price pings that train you to ignore them, so the real bargains slip past unread. By bundling everything into one scheduled email, Pax creates a fixed window for reviewing options and booking on the spot — which fits the broader reality that good fares rarely last long.
Now the catch: Pax only currently works for a select group of Canadian airports. Travellers in the US won't get the assistant's personalised digests yet, though FlightHub is one of the largest booking platforms in North America and expansion looks likely. In the meantime, Americans near the border have a workaround — cities like Vancouver and Toronto sit within reach of hubs such as Seattle, Detroit and New York, so a border hop can unlock access to the deals. And it's worth separating the tool from the platform: FlightHub itself books flights in and out of major airports worldwide. Only the Pax assistant is geographically limited, and only for now.
Why should a traveller care? Because fare-comparison fatigue is real, and tools that reduce the noise while surfacing genuinely below-average prices are rare. If you're based in or near Canada, Pax is a low-effort, zero-cost way to get a weekly shortlist of deals with the math done for you. If you're American, there's nothing to use yet — but the fact that a major OTA is building AI around deal-spotting (rather than another chatty search box) suggests this kind of weekly, personalised digest will spread. For now, the old rules still apply wherever you live: keep your destination options open, know a good price when you see one, and book before it disappears.
For Canadian travellers, it takes about a minute to sign up with an email and home city — no fee, no app, just one email a week to triage. sceptics of AI travel tools may find this one refreshingly restrained.
