Airfare is typically the single largest expense in any travel budget, and the cost gap between economy and business class can feel impossibly wide. But according to financial blogger and advisor Michele Kief, there's a lesser-known strategy that savvy travelers are already using to bridge that gap — and it doesn't require elite frequent flyer status or a corporate expense account.
The strategy is bidding for upgrades, and Kief considers it one of the most underutilized tools available to everyday flyers. Many international airlines now operate online auction systems through which passengers can submit bids for available premium cabin seats before their scheduled departure. These auctions are typically triggered when a flight has unsold upgrade inventory, and the airline would rather earn something for those seats than fly with them empty.
Here's how it generally works: After booking your ticket, you may receive an email from the airline inviting you to bid on an upgrade for your specific flight. You log into the airline's portal, submit a bid within a specified range, and wait. If your bid is accepted — often at a price significantly lower than the standard upgrade cost — you'll receive confirmation before the flight departs. The result? Business or premium economy seating at a fraction of the retail price.
Kief emphasizes that this approach is particularly well-suited for non-elite travelers who rarely qualify for complimentary upgrades through loyalty programs. Instead of hoping for a last-minute bump at the gate, the bidding system gives every passenger a proactive path to a more comfortable seat.
As with any auction, success isn't guaranteed. But even a failed bid costs nothing, making this a zero-risk strategy worth attempting on every eligible international flight. Kief advises travelers to research each airline's specific process, as program structures, bidding windows, and minimum bid thresholds vary from carrier to carrier.
Beyond upgrade bidding, Kief's broader message around airfare is one of patience and preparation. Flexible travel dates — even a shift of a day or two — can yield substantially lower fares. Booking well in advance, or in some cases at the very last minute, can also unlock pricing that standard searches miss.
Michele Kief believes that informed travelers are empowered travelers. Understanding the mechanics behind airline pricing and upgrade systems transforms what often feels like a frustrating guessing game into a navigable process. With a little research and a willingness to engage with the system on its own terms, flying comfortably doesn't have to come with a premium price tag.
