Air Lines trying to stay afloat with lower income families

I usually take 2 flights home each year to Nova Scotia. When i first flew out here it costed me 700 for a one way flight into edmonton and now i just flew home with my wife and it cost us together 700 round trip. Air lines are giving seat saver deals everyday now to try and intice people to travel more often because they are offering super cheap flights. It makes it a lot easier for students to fly because of such low prices and since students dont make that much money.
