Google Hotels and Google Flights are the best places to begin travel research in 2026, but they are metasearch tools rather than always being the merchant. Booking.com is the strongest broad accommodation marketplace, Expedia is best for travelers combining hotels, flights, cars, or packages, and Hotels.com is useful for hotel-focused shoppers already participating in One Key. The best place to pay is often the airline or hotel directly after comparing the total price.
| Site | Best for | Loyalty | Main advantage | Main drawback |
|---|---|---|---|---|
| Google Travel | Comparing flights and hotels | None as an OTA | Fast date/price exploration | Redirects elsewhere to book |
| Booking.com | Accommodation breadth | Genius, eligibility-based | Huge hotel and alternative-stay inventory | Property policies vary |
| Expedia | Packages and one account | One Key in participating markets | Flights, hotels, cars, activities | Intermediary during disruptions |
| Hotels.com | Hotel search in One Key markets | One Key | Hotel-focused interface | Same Expedia Group ecosystem |
| Direct booking | Status, changes, support | Hotel/airline program | Fewer intermediaries | Not always cheapest |
Start with metasearch
Google Flights provides calendar pricing, date grids, filters, price tracking, and routing comparisons. It can show airline and agency sellers, but the seller’s terms govern payment and support. Google Hotels maps properties and compares rates across direct and third-party channels.
Metasearch results can lag or omit taxes until later. Click through, reproduce the itinerary, and confirm baggage, room type, cancellation, resort fees, currency, and payment schedule before comparing.
Booking.com: best accommodation selection
Booking.com lists hotels, apartments, guesthouses, resorts, hostels, and other stays across a wide geographic footprint. Genius discounts or benefits depend on account level, property participation, dates, room, and current program terms.
The marketplace contains both pay-now and pay-at-property rates, refundable and nonrefundable policies, and independently managed properties. Read the exact room rules. A property’s overall page may advertise breakfast while the selected rate does not include it.
Our top pick: Booking.com
Expedia: best for packages
Expedia can bundle air, lodging, car rental, cruises, and activities, sometimes producing a package price unavailable from individual components. One Key lets members earn and redeem OneKeyCash across participating Expedia Group brands and markets under current terms.
Expedia announced updated One Key terms effective July 28, 2026 or a later notified date. Review the live terms, particularly eligible bookings, expiration, price guarantees, and redemption restrictions.
Packages complicate changes. A hotel cancellation, airline schedule change, and third-party transfer may have different responsible parties. Document each confirmation number.
Hotels.com: hotel-focused Expedia alternative
Hotels.com shares Expedia Group inventory and One Key in participating markets. Search results, member prices, service channels, and promotions can differ even when the underlying room is similar.
Older reviews praising a “stay ten nights, get one” program may be obsolete in markets migrated to One Key. Compare current earning and elite benefits rather than historical value.
Why booking direct often wins
Hotel elite-night credit, points, upgrades, mobile keys, and flexible support commonly apply best to direct bookings. Airlines can usually reissue or change their own tickets more easily than an online agency ticket. Direct rates may include member discounts after free signup.
An OTA can still win on package savings, regional inventory, payment options, or a clearly cheaper identical rate. Save screenshots of room name, bed type, taxes, inclusions, and cancellation deadline.
A reliable booking checklist
Compare final currency and total, including taxes, resort fees, baggage, seat selection, cleaning fees, and card foreign-transaction fees. Confirm whether payment is collected now or locally and whether local taxes remain due.
For flights, verify operating carrier, airport, connection time, self-transfer, baggage through-check, and visa/transit requirements. For hotels, verify occupancy, child policy, bed type, check-in hours, and accessibility directly with the property when essential.
Verdict
Research with Google, use Booking.com for accommodation breadth, Expedia for packages, and Hotels.com when its interface or One Key offer is best. Before paying, compare the identical booking direct. The cheapest headline is not the cheapest trip when support, baggage, taxes, and flexibility differ.

FAQ
Are Booking.com and Expedia the same company?
No. Booking.com belongs to Booking Holdings; Expedia and Hotels.com belong to Expedia Group.
Do OTAs have the same hotel rooms?
They may sell the same room type under different allocation, payment, and cancellation terms. Compare the full rate details.
Is a nonrefundable rate worth it?
Only when the savings compensate for losing flexibility and travel insurance clearly covers relevant risks.
Who handles a problem at check-in?
Contact the property and booking merchant. The party that charged the card and issued confirmation often controls changes, but responsibilities vary.
