Unclear
The per-cabin rules on the page say 40 x 30 x 15 cm (16 x 12 x 6 in), and that figure is shown here. The page's baggage-calculator section also shows a variant with "1 handbag or backpack (45 x 36 x 20cm)". It's unclear which routes or fares that applies to, so check BA's baggage calculator for your booking.

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:
