The short answer: One Key is Expedia Group’s free loyalty programme across Expedia, Hotels.com and Vrbo — and in 2026 it quietly became two different programmes. In the US, the old flat 2% is gone: earn is now tiered (Blue 1%, Silver 2%, Gold 2%, Platinum 3%) and standalone flights earn nothing. In the UK, earn stayed flat 2% — but Hotels.com UK left One Key entirely for a relaunched Hotels.com Rewards. In both markets, Blue members earn nothing at all on Vrbo. Most explainers online still describe the pre-2026 programme; this one works from the current official terms (US terms effective 28 July 2026; UK terms effective 8 April 2026). (Expedia offers we track are on our Expedia store page.)
The basics that didn’t change
One Key is free and automatic — creating an Expedia account enrols you — and it’s exactly three brands: Expedia, Hotels.com and Vrbo. One account, one shared OneKeyCash balance across them. You must be signed in before booking to earn. The currency is simple: $1 of OneKeyCash = $1 of travel (UK: £1 = £1), with no blackout dates, and you can spend it booking travel for other people. It is never cash, never transferable, and it lives or dies by an activity rule: book or redeem at least once every 18 months, or the entire balance expires (promotional OneKeyCash can expire sooner).
US: the tiered earn table (current)
| Where | Blue | Silver | Gold | Platinum |
|---|---|---|---|---|
| Expedia — eligible hotels, rentals, activities, packages*, cars, cruises | 1% | 2% | 2% | 3% |
| Hotels.com — eligible hotels, rentals, cars | 1% | 2% | 2% | 3% |
| Vrbo — participating properties | 0% | 1% | 2% | 2% |
| Standalone flights (any brand) | 0% | 0% | 0% | 0% |
*Packages earn on their non-flight portions. “Eligible” excludes taxes and fees and anything paid at the property — you earn on the room/product rate, not the full checkout total. Coupons used on a booking reduce the amount you earn on.
Three US changes deserve emphasis. Flights no longer earn OneKeyCash at all (the old 0.2% was removed; flights still count as Trip Elements toward tier status). Blue members — most casual users — now earn 1%, half the old rate. And the old Hotel Price Guarantee has been sunset. The defence of the new structure is at the top: Platinum’s 3% plus VIP Access rates (below) can beat the old flat 2% — for the small minority who reach Platinum.
UK: flat 2%, but Hotels.com walked away
The UK kept the simpler deal: 2% in OneKeyCash on eligible bookings at every tier, plus 0.2% on flights — no tiering. But the brand map changed underneath it. Since April 2026, Hotels.com UK no longer earns One Key; it runs a relaunched Hotels.com Rewards instead: you collect Reward Progression Nights, only counting stays averaging £75+ per night, and 10 nights = £100 of Hotels.comCash — which the UK terms define as the same currency as OneKeyCash. The UK migration ran 8 April – 8 May 2026 and appears to have been phased, so some UK accounts saw different states at different times. Practical consequence: a UK traveller’s Expedia and Vrbo bookings earn One Key; their Hotels.com bookings now play a completely separate (and, for pricier stays, arguably better) game. Cross-border warning: your earn rules follow your account’s programme version, so US and UK advice is no longer interchangeable — most “One Key explained” content that doesn’t specify a country is now wrong somewhere.
Tiers: Trip Elements, thresholds and Member Prices
Status is counted in Trip Elements per calendar year — broadly, qualifying booking components worth at least $25 (US) / £20 (UK) each after coupons and OneKeyCash are applied:
- Blue: entry tier, no elements required
- Silver: 5 Trip Elements
- Gold: 15 Trip Elements
- Platinum: 30 Trip Elements
Status lasts the rest of the qualifying year, the whole following year, and through 28 February of the year after. Separately, tier drives Member Prices: Blue 10% or more off selected properties, Silver 15% or more, Gold and Platinum 20% or more. For most members, Member Prices are quietly worth more than the earn itself — a 10–20% price cut now beats 1–3% cashback later, every time. When we built our London on a Budget guide, the same principle applied: the headline saving mechanism is rarely the real one.
A worked year: what the tiers are actually worth
Take a US traveller booking six hotel nights a year at $150 a night — $900 of eligible spend, all on Expedia, no VIP Access properties. At Blue (1%), the year earns $9. At Silver/Gold (2%), $18. At Platinum (3%), $27. Now the same traveller at Gold booking VIP Access properties instead: 4% = $36, plus Member Prices of 20%+ on the rooms themselves — on $900 of rooms, even a conservative Member Price saving dwarfs the cashback. Two conclusions follow. First, OneKeyCash earn alone is a minor rebate, not a strategy — nobody should route bookings for 1–3%. Second, the programme’s real value is concentrated exactly where Expedia wants it: Member Prices for everyone, and VIP Access earn for the top tiers. For UK members the maths differs in shape: flat 2% on £900 of spend is £18 regardless of tier, and the relaunched Hotels.com Rewards is the richer scheme on paper for qualifying stays — 10 nights at exactly £75 averages £750 of spend returning £100 (13.3%), though the return percentage falls as nightly rates rise above the threshold, and sub-£75 nights earn nothing at all.
The Vrbo trap
The single most-missed rule in the programme: on Vrbo, Blue members earn 0% — in both markets. Earning on Vrbo starts at Silver (1%) and tops out at 2% (Gold/Platinum), and only at participating properties. A Blue member who books all their stays on Vrbo — a very common pattern for families renting houses — accumulates nothing while believing they’re in the programme. If Vrbo is your main brand, your tier progress has to come from Expedia or Hotels.com bookings (US) before Vrbo spends start counting for earn.
VIP Access: the earn rates that actually move
VIP Access is an invitation-only network of 20,000+ properties (selected on review scores). Its enhanced earn is where One Key gets generous:
- Silver: 3% · Gold: 4% · Platinum: 6% in OneKeyCash at VIP Access properties (US programme pages; note some regional Expedia pages still display a 5% Gold figure — an inconsistency in Expedia’s own estate that we’ve flagged rather than resolved)
- Silver and above get in-stay perks; Gold and Platinum get room upgrades when available
- The catch in the terms: VIP perks never apply on third-party-supplied rates
For a Gold member, a VIP Access hotel at 4% plus a 20%+ Member Price is the closest One Key comes to the old Hotels.com rewards generosity — narrow, but real.
Spending OneKeyCash: the rules and the flight trap
Redemption is 1:1 with no blackout dates — but the boundaries matter:
- Flights trap: you can only pay with OneKeyCash if your balance covers the entire fare including taxes and fees. A $187 balance cannot part-pay a $210 flight.
- Not usable on: Pay Later bookings, buy-now-pay-later, cruises, most insurance products, and charges payable at the property.
- No stacking, generally: OneKeyCash generally cannot be combined with coupons, gift cards or other promotions in the same booking.
- Cancellation risk: if a booking paid partly with OneKeyCash is partially refunded, the OneKeyCash portion can be forfeited rather than returned.
- Only the booker earns — the named traveller doesn’t.
- Programme risk, for completeness: the terms let Expedia end the programme; if it ever did, members would have 60 days to spend accumulated balances. Standard clause, worth knowing before you treat a balance as savings.
A pattern worth seeing across all of these rules: OneKeyCash is engineered to be just sticky enough — valuable anywhere across three brands, but fenced off from flights unless it covers everything, from coupons in the same basket, and from accounts that go quiet for 18 months. None of that makes it a bad programme. It makes it a programme whose value depends entirely on using it the way it’s shaped: hotels and rentals first, flights last, and never as a reason to book something you wouldn’t otherwise book.
What happened to your old points and free nights
Legacy members were migrated, and the treatment was split. Expedia Rewards points converted at 100 points = $1 of OneKeyCash — full value. Hotels.com Rewards reward nights converted at full value, but stamps (part-nights) converted at just 10% of each night’s value. That’s the devaluation in one line: the old Hotels.com scheme returned roughly 10% (a free night per ten stamps); its replacement earns 1–3% in the US. Anyone who loved the old programme and feels One Key is thinner is, on the published numbers, simply right — except at VIP Access properties at the top tiers.
New for late 2026 (official announcements)
Expedia announced additional top-tier benefits in October 2026: delayed-flight lounge access for Gold and Platinum members (flights delayed 90+ minutes, LoungeKey network, with a $20 OneKeyCash fallback; a pilot covering flights booked 30 September 2026 – 31 December 2027), Price Drop Protection for Gold/Platinum on app-booked flights (the difference paid in OneKeyCash if the fare drops), and tier pricing on CLEAR+ in the US. Valuable if you’re already Gold+; not a reason to chase status from zero.
Who should bother — and who shouldn’t
Bother if: you already book through Expedia or Hotels.com (the membership is free and automatic, so the only real action is staying signed in); you’re UK-based and book Expedia/Vrbo regularly at flat 2% with no tier chase; or you’re a genuinely frequent traveller who can hold Gold or Platinum, where VIP Access earn (4–6%) plus 20%+ Member Prices plus the new lounge and price-drop benefits add up to a real discount stack. Also bother to set one diary rule: never let 18 months pass without a booking or redemption, because the expiry is total.
Don’t reorganise your travel around it if: you’re a Blue member booking mostly Vrbo stays (you earn 0% — book direct or elsewhere until other bookings lift your tier); you were loyal to the old Hotels.com free-night scheme (its ~10% return is gone in the US, and the UK replacement only rewards £75+ nights); or you collect airline/hotel points elsewhere — One Key’s 1–3% doesn’t beat a good hotel programme’s earn on its own brand, and splitting loyalty usually loses to concentrating it. The honest summary: One Key is a pleasant rebate on bookings you’d make anyway, with two sharp edges (the Vrbo Blue rule and the flight-redemption trap) that cost real money only if you don’t know them. Now you do.
Frequently asked questions
Is Expedia One Key free?
Yes. Creating an Expedia account enrols you automatically, and the same account and OneKeyCash balance work across Expedia, Hotels.com and Vrbo. You must be signed in before booking to earn.
How much do you earn with One Key in the US?
Since the 2026 overhaul, earn is tiered: Blue 1%, Silver 2%, Gold 2%, Platinum 3% on eligible hotels, rentals, activities, packages (non-flight parts), cars and cruises — and nothing on standalone flights. VIP Access properties pay enhanced rates (Silver 3%, Gold 4%, Platinum 6%). The UK still earns a flat 2% (plus 0.2% on flights), but Hotels.com UK no longer participates.
Does One Key work on Vrbo?
Partly — and this is the trap. Blue members earn nothing on Vrbo in either market. Earn starts at Silver (1%) and reaches 2% at Gold and Platinum, at participating properties only.
When does OneKeyCash expire?
Your balance survives as long as you make an eligible booking or a redemption at least once every 18 months. Miss that window and the whole balance is lost. Promotional OneKeyCash can have shorter expiry.
Can I pay for a flight partly with OneKeyCash?
No. For flights, your balance must cover the entire fare including taxes and fees — partial payment isn’t offered. Hotels and other products are more flexible, though OneKeyCash generally can’t be combined with coupons or gift cards.
What happened to Hotels.com free nights?
In the US, reward nights converted into OneKeyCash at full value (stamps at 10% of a night’s value) when One Key replaced the scheme. In the UK, Hotels.com has since left One Key (April 2026) and runs a relaunched Hotels.com Rewards: nights averaging £75+ count, and 10 nights earn £100 of Hotels.comCash.
Sources and how we checked
All earn rates, tier thresholds, redemption and expiry rules are from Expedia’s official One Key terms and programme pages — US terms effective 28 July 2026 and UK terms effective 8 April 2026, read in November 2026 — with the October 2026 benefits from Expedia Group’s official press release. Cross-region inconsistencies we found in Expedia’s own pages (a 5% Gold VIP Access figure on some regional sites versus 4% on US pages) are flagged in the text. We do not repeat third-party explainers’ pre-overhaul figures. One eligibility note for transparency: Expedia’s affiliate programme has historically restricted coupon publishers, which is a matter for the site owner and doesn’t change the consumer mechanics described here.
