Need more allowance? Add the bag online, before the airport

Many airlines charge more at the airport or gate than when you add a bag online. Flair's own page, for example, lists a carry-on at $49–$109 when booking but $99–$154 at the airport gate (CAD, or USD for US-originating trips). Check your airline's current price on its official site:
