Conclusion
For flights, start at Google Flights to set the price benchmark, then book direct with the airline whenever possible. For hotels, Booking.com is the default, with Hotels.com offering better loyalty value if you travel often. For Asia, Trip.com is genuinely cheaper. Always check the airline's own site after using metasearch — direct bookings often have better customer service when things go wrong.
Frequently Asked Questions
For flights, direct with the airline is usually equal or cheaper after taxes and provides better customer service in disruptions. For hotels, OTAs (especially Booking.com and Hotels.com) often have lower prices and better cancellation, but elite hotel loyalty members may earn more direct.
Standalone travel insurance (e.g., World Nomads, Allianz) is generally a better deal than OTA add-ons. For trips over $1,000 with non-refundable bookings, especially international, it's usually worth it. Skip on cheap, refundable domestic trips.
1) Use Google Flights to set the benchmark. 2) Check the airline's own website. 3) Try nearby airports and adjacent dates. 4) Use Hopper's predictions for whether to book now or wait. 5) Avoid checking flights in incognito doesn't actually save money — that's a myth — but flexibility is genuinely worth ~$50-200 per ticket.
