Factor in baggage fees: Low-cost carriers on this route often advertise attractive base fares but charge separately for checked luggage.

Search in private browsing: Some booking sites use cookies to track repeat searches and may show higher prices after multiple lookups. Use an incognito or private window — or just use Booked AI, which pulls live prices without any tracking markup.
