Is it always cheaper to book through a third-party site found on an aggregator?

Not necessarily. While aggregators may display lower prices from various Online Travel Agencies (OTAs), these prices may not always reflect the final cost after service fees, baggage add-ons, or currency conversion. Travelers should compare the total cost against direct airline booking options to ensure the final price is accurate.

Why do search results sometimes differ between Google Flights and Skyscanner?

Search engines utilize different inventory access and partnerships. Each platform maintains its own set of data connections with airlines and various travel providers. Consequently, the specific providers indexed by each tool may vary, leading to different pricing and availability results for the same itinerary.

Which tool is better for tracking flight status and updates?

Skyscanner provides a free Flight Tracker tool that allows users to monitor departure and arrival times, as well as receive updates regarding delays or cancellations for their booked itineraries, as noted in their service documentation.
