The changing of fares according to demand is a common practice in airlines that allows travelers to reserve high-value premium cabins at a reduced price with intelligent Booking techniques. Adjustable dates and other airports have a higher chance of detecting good offers. The best cheap business class flights will be those when the company is trying to populate the remaining seats. Group Booking is also advantaged by this trend since sometimes premium cabins release a number of seats as a single group at good rates.
