Recently, Air Canada is discounting in airlines. 15% off is really an impressive amount, especially during the Christmas. As far as I am concerned, air lines could make a lot of margin in this way.
For international students, Christmas is a good holiday when they can go home and reunion with their families. For tourists, the sales stimulate them to fly over the world and have a good time. For the air line, a slight decrease in price leads to a tremendous increase in demand, which maximization the profit. In addition, since the ticket price increases as time flies, customers usually book tickets in advance. Also, some rules are published that if the customers want to cancel the tickets, they have to pay a certain amount of charge. Therefore, the air line may not lose and seats are guaranteed in some aspect.
In conclusion, companies should be good at seeking the business opportunities. Such measures made by the air lines are absolutely beneficial to the companies themselves as well as the consumers.
