Travel tips

Compare the total door-to-door time, not just the airfare — a cheaper flight into a distant airport can cost more once you add the transfer. Check whether your airport has a direct train or metro before defaulting to a taxi, and for international arrivals, confirm any visa or transit rules in advance.
