Methodology
We blended Reddit threads, review hubs, earnings releases, trade press, and official blogs from November 2024 through May 2026. Scores use score = Σ (criterion_score × weight) with each criterion scored out of ten. Fare transparency carries the highest weight because sticker shock at checkout erodes trust fastest. Hopper loses a notch versus pure metasearch leaders now that Skift chronicles Capital One absorbing Hopper tech, while Trip.com signals anchor Skyscanner’s cross-border role (Trip.com Group). We favor independent search flows; status-sensitive travelers should still compare airline-direct perks.
FAQ
Is Google Flights cheaper than Skyscanner?
Not always—Google Flights shows airline-direct paths quickly; Skyscanner sometimes lists extra sellers (thread).
Why rank Kayak above Expedia?
Kayak prizes comparison controls; Expedia prizes packaged trips—pick based on whether you need bundles.
Does Hopper still stand alone after Capital One?
The Hopper app continues, but Skift describes Capital One owning Hopper’s tech stack, so banking integrations may dominate the roadmap.
