Air Canada offering deal to the passengers who have bought economy class tickets but are willing to offer up some extra bucks to improve their traveling experience.
Passengers can make a cash bid to upgrade their seat to premium economy or business class.
Bids are made online using a sliding scale with a set minimum and maximum amount. When passengers pick their price, a chart lets them know the strength of their offer.
The travelers find out if they have the winning bid about 48 hours before departure.
The deal is only available for selected flights, depending on market demand. Eligible customers will get an email 10 days before takeoff, inviting them to make an offer.
