Expedia and One Key
There is a version of travel loyalty that works perfectly. You fly with one airline, stay in hotels from one or two major groups, earn points and status on every trip, and redeem them for upgrades and free nights at properties you would have booked anyway. For frequent business travellers whose itineraries are dictated by corporate routes and city-centre Marriotts, this system delivers real value.
But most travel does not look like that.
A family choosing a villa in the Greek islands is not cross-referencing Hilton’s property map before they pick their destination. A couple booking a long weekend in a Cotswolds farmhouse is not searching for IHG properties in Burford. Someone planning a cycling holiday in rural Tuscany is not filtering by Marriott Bonvoy hotels in the Val d’Orcia. They are choosing where they want to go and finding the best place to stay when they get there — which, more often than not, is a private villa, an independent hotel, a holiday apartment, or a boutique property that no loyalty programme has ever heard of.
This is not a failure of loyalty strategy. It is simply the reality of how most people travel. The destination comes first. The property follows. Loyalty is a bonus that applies when it happens to align — not a framework that should dictate where you go or what you stay in.
Understanding this distinction is the most important thing a points traveller can grasp. Chase loyalty hard when the hotel you want is in the programme. Do not let loyalty considerations push you into a hotel you do not actually want. And for every trip that falls outside the loyalty grid entirely, make sure you are earning something from it anyway.
That last part is where Expedia One Key comes in.
What is One Key?
One Key is Expedia Group’s loyalty programme, available in the UK across Expedia and Vrbo. It is free to join and earns a rewards currency called OneKeyCash on eligible bookings. The mechanic is simple: £1 of OneKeyCash equals £1 off a future booking. No conversion rates, no transfer partners, no complexity. OneKeyCash does not expire as long as you make or redeem an eligible booking at least once every 18 months.
There are four tiers based on trip elements. Each individual hotel room night, each flight ticket, each car rental day and each activity ticket counts as one element — so a seven-night villa stay plus seven days of car hire plus return flights for two people earns well over 20 elements from a single family holiday. The minimum spend per element is £20 excluding taxes.
| Tier | Elements needed | Member price saving |
|---|---|---|
| Blue | Base (automatic) | 10% or more |
| Silver | 5 per year | 15% or more |
| Gold | 15 per year | 20% or more |
| Platinum | 30 per year | 20% or more |
Status resets each calendar year on 1 January. Because hotel nights, car rental days and flight tickets each count individually, a single family holiday can generate enough elements for Gold or even Platinum status in one trip.
All members earn the standard 2% OneKeyCash rate on every eligible booking regardless of tier. The higher tiers unlock an enhanced earn rate — up to 3% at Silver, 4% at Gold and 6% at Platinum — but only when staying at VIP Access properties. VIP Access is Expedia’s collection of highly-rated hotels that meet certain quality and service standards. For stays outside VIP Access properties, the 2% rate applies to everyone.
What you earn
The standard earn rate is 2% in OneKeyCash on hotels, holiday rentals, packages, car rentals and activities. Standalone flights earn 0.2% — poor enough that booking flights through Expedia purely for the rewards makes no sense. On a £500 flight you would earn £1.
Package bookings are the exception. When a flight and hotel are booked together as a package the earn rate on the flight element rises to 2%, in line with everything else. One practical note: OneKeyCash earned on package bookings cannot be redeemed on package bookings — it must be spent on standalone hotels, car rentals, activities or other eligible bookings. Earn on the package, spend on the next trip.
Always book Expedia packages as Pay Now rather than Pay Later. OneKeyCash can only be redeemed on Pay Now bookings — Pay Later bookings are not eligible for redemption.
Stacking with your other rewards
One of One Key’s most underappreciated qualities is how it layers on top of rewards you are already earning.
Book through Expedia using a rewards credit card and you earn card points on the full spend — Membership Rewards on an Amex, for example — exactly as you would booking anywhere else. Book a flight through Expedia and you continue to earn your frequent flyer miles with the airline as normal. One Key does not interfere with either.
The result is that a booking through Expedia can earn in three places simultaneously: card points, OneKeyCash and airline miles. For the trips where hotel loyalty is not in play — which, as we have established, is a lot of trips — that three-way earn is genuine incremental value.
The loyalty trade-off: when it matters and when it does not
For branded hotel stays, the trade-off is real and significant. Book a Hilton, Marriott, IHG or Hyatt property through Expedia rather than direct and you will typically receive no hotel loyalty points and no elite night credit. The 2% OneKeyCash does not compensate for lost hotel points and the elite nights that build status. For anyone actively chasing Hilton Gold, Marriott Gold or IHG Platinum, booking those properties through a third party is almost always the wrong call.
But this trade-off only exists when the hotel you want is already part of a loyalty programme — and that is a much smaller slice of travel than most loyalty content suggests.
The trips loyalty cannot touch
Consider how much of a typical family’s annual travel falls outside the branded hotel grid entirely.
Expedia Group lists around 1.2 million hotels and other accommodation across its platform — far beyond the reach of any single loyalty programme. More significantly, through Vrbo it offers access to approximately 2.4 million private and alternative accommodation options: villas, apartments, cottages, farmhouses, chalets, and holiday homes of every description. None of these come with loyalty points. None of them ever will. But all of them are bookable through Expedia, and all of them earn OneKeyCash.
The Greek island villa your family has been looking at. The apartment in Lisbon. The mountain chalet in the Alps. The converted barn in Suffolk for a long weekend. Every one of these bookings is currently earning you nothing beyond your credit card points — unless you book through Expedia, in which case it earns you 2% back in OneKeyCash on top of whatever your card gives you.
For a £3,000 villa booking that is £60 in OneKeyCash. Not life-changing. But entirely free, earned on a booking you were making anyway, from a property that will never appear in a loyalty catalogue. Stack that across three or four non-loyalty trips a year and the balance accumulates meaningfully.
Rural and boutique destinations sit in the same category. A small independent hotel in a Cornish fishing village, a family-run inn in rural Umbria, a boutique riad in Marrakech with no affiliation to any international group — none of these have loyalty programmes, and booking direct earns nothing beyond your credit card points. Booking through Expedia adds OneKeyCash to that earn at no cost.
Loyalty programmes earn nothing on villas, private apartments, independent hotels, or boutique properties outside the major groups. Expedia One Key earns 2% OneKeyCash on all of these — stacked on top of your credit card points — at no cost and with no trade-off.
The practical approach
The cleanest way to use Expedia One Key is as a passive earner for everything outside your primary loyalty strategy. Not instead of it — alongside it.
When the hotel you want is a Hilton, Marriott, IHG or Hyatt property: book direct, earn hotel points and elite nights, use your loyalty rate. Expedia adds nothing here that compensates for what you give up.
When the property you want is a private villa, an independent hotel, a holiday apartment, or anything else outside the loyalty grid: book through Expedia, earn OneKeyCash on top of your card points, and let the programme quietly build a balance you can spend on a future trip.
The OneKeyCash you earn on a week in a Corfu villa could pay for a night in a hotel on your next city break. The rewards from a cottage in Devon could knock money off a future car hire. It is not a high-octane points strategy. It is a sensible habit that extracts value from bookings that would otherwise earn nothing beyond your card points.

What is happening with Hotels.com?
Hotels.com — a sister brand within Expedia Group — is separating from One Key on 8 April 2026 and launching its own new rewards scheme. The new Hotels.com Rewards operates on a stay 10 nights, earn £100 Hotels.comCash structure. Qualifying nights must cost at least £75 on average including taxes. The £100 credit can be split across multiple future bookings and can also be used toward flights on Expedia. Any unspent OneKeyCash converts to Hotels.comCash at full value when accounts transition.
The Hotels.com scheme is worth considering alongside Expedia One Key for independent hotel stays, particularly for mid-market travellers booking rooms in the £75–£120 range where the flat £100 reward represents good value. For higher-spending stays the flat cap makes the return less competitive. And the same fundamental rule applies: booking via Hotels.com means giving up chain hotel loyalty points and elite nights, so it works best for independent properties and destinations where chain loyalty has no foothold.
For a full breakdown of how the new Hotels.com scheme works, how it compares to the original, and who it suits, see our Hotels.com Rewards 2026 guide.
Is One Key worth joining?
Yes — without qualification. It is free, it requires no behaviour change beyond making bookings you were already going to make, and it earns on precisely the trips that traditional loyalty programmes ignore.
Join it. Link it to your Expedia account. Use it whenever you are booking outside the loyalty grid. And do not overthink it — One Key is not a programme to optimise around. It is a programme to have running in the background, earning quietly on the travel that matters most to most people: the holidays chosen for the destination and the property, not the points.
Loyalty programmes work brilliantly when the hotel you want happens to be in the programme. Expedia One Key works brilliantly when it is not. Between them, they cover almost everything. Join One Key for free, use it for villas, apartments, independent hotels and any trip where branded loyalty has no foothold, and earn on bookings that would otherwise give you nothing back. The Greek island villa comes first. The points are the bonus.
