CheapOair is an online travel agency that aggregates fares across hundreds of airlines and applies its own promo codes on top, which is where an OTA can beat booking direct. Code FALL40 discounts autumn bookings by up to $40 off service fees, applied at checkout. Fall is structurally the cheapest stretch of the year to fly domestically — schools are back, summer demand has collapsed and airlines are still running full capacity into October — so a code stacked on shoulder-season pricing compounds rather than just nibbling at a high fare. The promotion runs through 6 September, and the discount applies to the booking, not to a specific route.
