If you're trying to decide between Booking.com and Expedia for your next hotel booking, you're comparing the two biggest travel platforms in the world. Both are legitimate. Both will get you a real hotel room. But they serve very different types of travelers, and understanding the differences can save you real money.
I've used both platforms extensively as a digital nomad since 2018. Here's what actually matters.
The quick answer
Booking.com is better for standalone hotel bookings. More properties, more reviews, better last-minute deals, and a loyalty program that doesn't expire.
Expedia is better for bundled trips. If you're booking flights + hotel + car together, Expedia's package discounts and cross-platform rewards make more sense.
Neither platform warns you about cockroaches, mold, or noise problems. That's a separate issue — and it's why I built DoNotStay.
Who owns what
Both platforms are owned by massive public companies, and each owns brands you might not realize are connected.
Booking Holdings (NASDAQ: BKNG) owns Booking.com, Priceline, Agoda, KAYAK, OpenTable, and Momondo. Revenue in 2025: $26.9 billion. Market cap: roughly $150 billion.
Expedia Group (NASDAQ: EXPE) owns Expedia, Hotels.com, Vrbo, Orbitz, Travelocity, Hotwire, and holds a majority stake in Trivago. Revenue in 2025: $14.7 billion. Market cap: roughly $30 billion.
Booking Holdings is about 5x larger. That scale shows up in the inventory: Booking.com lists roughly 31 million accommodation listings across 220+ countries. Expedia offers about 3.5 million properties.
The geographic split matters too. Booking.com earns about 90% of its revenue outside the US, with deep dominance in Europe. Expedia gets over 60% of its revenue from the US. If you're booking a hotel in Barcelona, Booking.com will have more options. If you're building a vacation package to Cancún, Expedia's ecosystem is designed for that.
Reviews: Booking.com wins by a mile
This is where it matters most for avoiding bad hotels.
Booking.com generates roughly 39% of all hotel reviews worldwide. Expedia generates about 5%. That's an 8:1 ratio. For almost any hotel, you'll find significantly more guest feedback on Booking.com — which gives you a much richer picture of what to expect.
The scoring works differently too. Both use a 1–10 scale, but Booking.com overhauled its system in 2025 to weight recent reviews more heavily. If a hotel's quality dropped in the last year, the score drops faster. Expedia still uses a simple average of all reviews — a hotel that was great five years ago but terrible now can still show a high score.
Booking.com also requires a written comment for any score of 1 or 10, which filters out drive-by ratings. And guests who showed up but didn't stay can still leave a review — which captures the worst experiences that other platforms miss entirely.
This review volume is exactly why DoNotStay analyzes Booking.com reviews specifically. The platform has the deepest, most detailed review dataset of any OTA. When our tool finds 8 separate reports of cockroaches across multiple years and nationalities, that pattern is only visible because Booking.com has the review depth to reveal it.
Pricing: same base, different discounts
The base price for the same hotel room is usually identical on both platforms. Hotels sign rate parity agreements that keep the nightly rate consistent across OTAs.
The real differences come from how each platform discounts.
Booking.com advantages: Better last-minute pricing (one study found it won 62% of the time, saving an average of $27/night). Mobile-only discounts of 10%+ on select properties. Genius loyalty discounts of 10–20% applied instantly at checkout.
Expedia advantages: Stronger bundle discounts — up to 30% savings when adding a hotel to a flight. More frequent promotional codes (averaging 3.4 per month). A $50 coupon when price match claims are approved.
Both offer price match guarantees. Booking.com accepts claims up to 24 hours before check-in. Expedia's deadline is midnight on check-in day.
Loyalty programs: lifetime vs annual reset
This is the sharpest strategic difference between the two platforms.
Booking.com Genius has three tiers unlocked by booking frequency: Level 1 (instant), Level 2 (5 bookings), Level 3 (15 bookings). Benefits include 10–20% discounts, free breakfast, and room upgrades at participating properties. The critical advantage: Genius status is lifetime. Once you earn it, it never expires.
Expedia One Key launched in 2023 across Expedia, Hotels.com, and Vrbo. It has four tiers based on "trip elements" booked per year. Instead of instant discounts, you earn OneKeyCash at 2% back, redeemable on future travel. The cross-platform earning is powerful — a family vacation with flights, hotel nights, and a rental car can rack up elements quickly. The catch: status resets every January 1.
For occasional travelers, Genius wins. For frequent travelers who book flights, hotels, and cars across Expedia's brand family, One Key's cross-platform earning can be more valuable.
Cancellation: Booking.com is more flexible for hotels
Neither platform sets universal cancellation terms — individual hotels define their own policies. But the structural differences matter.
Booking.com widely offers "pay at property" where your card isn't charged until check-in, and actively encourages free cancellation options. Many listings default to free cancellation up to 24–48 hours before arrival. This makes Booking.com ideal for travelers who want to book now and decide later.
Expedia leans toward upfront payment but offers paid add-on protections: a "Cancel for Any Reason" option on select flights and a "Vacation Waiver" covering change and cancellation fees across packages. If you're assembling a complex itinerary with non-refundable flights, these products provide peace of mind Booking.com doesn't match.
The search results aren't neutral
Both platforms admit that hotel commission payments influence which properties appear first in default search results. Most travelers don't realize this.
On Booking.com, the "Preferred Partner Program" gives the top 30% of properties in a destination a visibility badge and roughly 65% more page views — in exchange for about 3% higher commission. That cost gets baked into room rates. The elite "Preferred Plus" tier can push commissions to 25–30%.
Expedia's "Accelerator Program" lets hotels bid additional commission for higher placement. Data shows a 1% increase moved one hotel from rank 22 to 15. A 10% increase jumped another from page 3 to page 1.
The first results you see on either platform are not necessarily the best value. They may simply be the hotels paying the most. Sort by price or guest rating to bypass commercial influences entirely.
Customer service: both are bad, differently
Customer support is the weakest point for both platforms. Trustpilot scores are grim: Booking.com sits at 1.8/5 from about 106,000 reviews, Expedia at 1.2/5 from 11,300.
The Better Business Bureau tells a different story: Booking.com holds an F rating with hundreds of unanswered complaints. Expedia maintains an A+ rating and BBB accreditation since April 2025 — meaning it at least responds systematically to formal complaints.
Common complaints across both: refund delays, blame-shifting between platform and hotel, unhelpful chatbots, and hidden fees at checkout.
The honest assessment: most bookings go smoothly on both platforms (both apps have 4.8/5 stars in app stores). But when things go wrong, getting resolution from either platform is painful. Expedia's formal complaint responsiveness gives it a slight edge for escalation.
Legal trouble: Booking.com is under more scrutiny
Booking.com faces significantly more regulatory action than Expedia — a consequence of its market dominance.
Spain fined Booking.com €413 million in 2024 for preventing hotels from offering lower prices on their own websites. The European Commission designated Booking.com a "gatekeeper" under the Digital Markets Act, forcing it to remove rate parity clauses across the EU. Over 10,000 European hotels have filed a class action seeking recovery of commissions paid under those now-illegal clauses. Texas secured a $9.5 million settlement over deceptive "junk fee" practices.
Expedia's legal issues are smaller: a $29.85 million verdict under the Cuba Libertad Act and a California class action over flight refunds.
For travelers, the gatekeeper designation is actually good news. Hotels in Europe can now legally undercut Booking.com's prices on their own websites. Always check the hotel's direct site after finding a property on either platform.
What neither platform tells you
Here's the thing both platforms have in common: neither one warns you about the specific problems guests experienced.
An 8.2 "Very Good" on Booking.com and an 8.4 "Excellent" on Expedia look nearly identical. But behind both scores could be reports of cockroaches in the breakfast lounge, stained sheets, or paper-thin walls. The scores are averages. Averages hide the worst experiences.
Both platforms show you the score. Neither shows you the pattern.
That's why I built DoNotStay. It's a free Chrome extension that analyzes every detailed review on a Booking.com hotel page and surfaces the problems that scores and badges hide — pests, hygiene issues, noise, safety concerns, scams — with evidence from actual guest reports.
Whether you find your hotel on Booking.com or Expedia, look it up on Booking.com and run DoNotStay before you book. The platform you book on matters less than the hotel you end up in.
