Emirates is selling empty adjoining seats to Economy Class passengers at check-in, enabling them to sit in an empty row at an extra cost.

The carrier is allowing passengers to buy up to three empty adjacent seats at check-in, with a price ranging from 200 to 600 United Arab Emirates dirham—about $55 to $165—depending on the flight. Passengers only can buy the seats at check-in counters, as they depend on availability on the day of the flight.

In addition, Emirates is giving discounts for excess and overweight baggage for travelers who pay for it in advance. The discounts range from 35 percent to 60 percent and must be booked and paid through a direct channel—the Emirates website, call centers or sales offices—at least four hours prior to departure.
