Southwest's current help page says the personal item must go under the seat in front of you, but gives no dimensions. Third-party figures exist but are not official, so none are shown here.

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:
