Expedia versus Kayak
Compare	Expedia	Kayak
Verdict	Depends	Worth it
Best for	Leisure travelers bundling flight + hotel	Deal-hunting leisure travelers
Who it's not for	Trips that might need changes or refunds	Travelers wanting one accountable party for the whole booking
Privacy	No known breaches of the core platform; two third-party incidents (2018 Orbitz, 2020 Prestige) exposed guest data.^⁸	Security page, dedicated team, and HackerOne bounty exist; two public incidents: a 2012 data-exposure glitch and a 2022 account-takeover disclosure.
Support quality	Refund and complaint volume dominates reviews	Complaint sites document hard-to-resolve booking disputes
Public sentiment	Polarized: travelers praise the deals and inventory but repeatedly report poor customer service and refund hassles.^¹	Users like the search experience, but a vocal minority report misleading prices, booking disputes, and hard-to-reach support.¹⁵
Biggest gotcha	Changes route through Expedia, not the airline or hotel; refund waits are common^⁶	ConsumerAffairs lists misleading-pricing complaints; confirm the final price before paying
