Practical, no-fluff guides to the kind of travel WRVR is built for: open-jaw routes, flexible dates, and trips where you care more about a good deal than a fixed itinerary.
1 · How to find cheap open-jaw flights
An open-jaw ticket flies you into one city and home from a different one - for instance, into Milan and home from Venice. The middle (Milan → Venice) you cover yourself by train, bus, or a cheap hop. Done well, it's both cheaper and a better trip than backtracking to where you landed just to fly home.
Why open-jaw can beat a round trip
Round-trip fares are priced on the specific city pair you pick. Two nearby cities can have very different fare levels on a given week - a budget carrier may flood one route while the other stays expensive. An open-jaw lets you take the cheap inbound to one city and the cheap outbound from another, instead of being locked to the worse of the two in both directions. You also save the time and money of returning to your arrival airport.
How to actually find them
Type a city or country, not just codes. In WRVR's From/To boxes you can type “Rome”, “Italy”, or a 3-letter code; pick a single airport or “All Rome airports” to let the arrival and departure cities float to wherever the fares are cheapest.
Use the nearby-airport radius. Under each box, open “+ nearby airports” and widen the radius so the search can pair, say, an arrival in Prague with a departure from Vienna.
Mind the ground gap. Open-jaw only pays off if the two cities are realistically connected. Check the overland transfer (train/bus) and fold its cost and time into your comparison - a €30 train that saves €120 on flights is a clear win; a €200 flight between them is not.
Compare against the round trip. Always sanity-check the equivalent round trip. Open-jaw usually wins on flexible routes, but not always.
WRVR does this pairing automatically: because it fetches one-way legs and joins them, an open-jaw itinerary is just another combination it ranks next to round trips, and each result shows the ground gap between the arrival and departure cities.
“Be flexible” is the oldest advice in cheap travel, and also the vaguest. Here's what flexibility is worth and how to use it deliberately.
Two kinds of flexibility
When you leave and how long you stay are separate levers, and they interact. A Friday departure carries a weekend premium; mid-week is usually cheaper. Trip length matters too - a fare can drop sharply if you stay one night longer or shorter, because it shifts your return onto a cheaper day. Searching a single date misses all of this.
Search a window and a range together
Give the search a date window - a long weekend, or “any time in July” - rather than one departure date.
Give it a range of nights - say 5 to 9 - instead of an exact duration. The engine then checks every length against every departure day and surfaces the cheap combinations.
Watch the trade-off, not just the price. The cheapest result might mean an awkward Tuesday-to-Sunday. WRVR lets you sort by price, total flight time, or convenience so you can see what a few euros of saving actually costs you in hassle.
The wider your window and night range, the more pockets of cheap pricing the search can find - flexibility is most valuable exactly when you have the most of it.
Three ways to say “when”
WRVR's Dates selector offers three modes, so you can describe your constraints the way you actually have them:
Flexible nights. The default: a departure window plus a range of nights away. Best when you're open on both dates and trip length.
Departure & return windows. Set an outbound window and a separate return window - “leave any time July 1-5, come back July 15-20”. Useful when the two ends are pinned to different events but each has some give. Nights becomes an optional extra trim.
Fixed dates in destination. Give the days you must be there - “in Rome July 10-14” - and WRVR finds the cheapest trip that arrives by the 10th and leaves on or after the 14th, allowing an earlier arrival or later departure if it's cheaper. Best for a wedding, conference, or any fixed event.
3 · One-way and multi-city trips without overpaying
One-way tickets used to carry a stiff penalty. On many short-haul and low-cost routes that's no longer true - two one-ways can cost the same as, or less than, a round trip, and they unlock itineraries a round trip can't express.
When one-way wins
Open-jaw and multi-city trips are just sequences of one-ways. If you're hopping between cities, pricing each leg independently is often cheaper than forcing a round-trip structure onto the trip.
Mixing carriers. One-ways let you fly out on whichever airline is cheapest that day and home on another - something a single round-trip fare won't do.
Uncertain return. If you don't yet know when or from where you're coming back, book the outbound now and the return later.
Things to check first
Long-haul can still penalise one-ways. On intercontinental routes a one-way is sometimes nearly the price of a return - compare before assuming.
Visa and immigration. Some countries want proof of onward travel; a one-way in can mean questions at the border.
Baggage adds up. Two separate tickets can mean paying for bags twice - fold that into the comparison.
In WRVR, switch the trip type to One way to search single legs across your whole date window, ranked the same way as round trips.
Building a multi-city trip
For a proper hop between several cities, switch the trip type to Multi-city. You get a route builder: your starting airport, then an ordered list of stops - add as many as you need, and give each stop its own range of nights to stay. WRVR prices the cheapest one-way for every hop across your date window and sums them, so a Rome → Athens → Istanbul trip is planned as one search instead of three.
Per-stop nights. Each stop has its own min-max nights, so you can spend “2-4 in Rome, then 3-5 in Athens”.
Return home, or don't. Tick Return home at the end to add a final hop back to your origin, or leave it off to end the trip at your last city.
