OnceOver

See the prices we have already collected without signing up.

Every date on one screen, not in ten tabs

OnceOver is for when two dates and a destination are not enough. You search by what matters to you: how long the flight and the layover are, which cities you change in and which airline you fly, which days you can leave, a route with long stops and anything else you need. An ordinary search can’t do this; here you run the search. Enter the route and a few possible days to leave and come back, and you get a price for every date pair under your conditions, as a table or as trips on a calendar.

Round trip or one way. We show how old every price is.

A price calendar on your terms

You have probably seen a price calendar before. This one works differently: you set the window for leaving and for coming back, every cell holds the cheapest price that meets your terms (how many stops, how long each layover may be each way, no self-transfer), and every price shows when it was retrieved and what the same flights cost at other sellers. You set your terms once, and they hold for the whole table.

The same example in numbers

One flight at four sellers, €

The same flights, 21% apart from seller to seller. Fare rules may differ: check them at the seller.

What it does

Where and how to fly

How the route is flown, when it is cheaper to go, and how to take in several cities on one trip.

Times are scheduled time in the air; the layover itself is not included.

Arrows show which way flights go through a city; a line without arrows means we do not know yet

Click a city to keep options through it plus direct flights; its card keeps it for the way out or the way back only, or hides it; you can pick several; click the direct line for direct only.

Ways with a price for these dates are in colour; ways the routes allow without a price for these dates are grey

The route map before any dates
Enter two cities. Before you pick any dates, the map shows whether there are direct flights and which cities you can connect through.
When it’s cheaper to fly
If your dates are open, say how many nights you want. We show which days over the coming months are cheapest to leave.
A trip through several cities
From home to one or two cities and back, spending as many nights in each as you like. We work out the cheapest way in separate tickets, one for each flight.

Your conditions on every price

You set your conditions once, and every price in the table already meets them.

Every date pair in one table
Pick a few days to leave and a few to come back. Departure dates run down the rows, return dates across the columns. Each cell holds the lowest price that passes your filters. The cheapest cell is the cheapest trip that suits you.
Layovers that suit you
Set how many hours you are ready to wait between flights, say 2 to 6, how many stops you accept and which airlines and airports suit you. Flights out and back are checked separately. The table updates at once without a new search, and your settings stay.
You can see how fresh each price is
We show the price the seller quoted. Every price shows the date it is valid for, so you can tell how far to trust it: our fresh prices matched checkout within 1.2%, day-old ones were off by up to 7%.

From the price to the ticket

Who sells the ticket and for how much, what exactly you are buying, and how to compare your options in one shortlist.

Every seller’s price for the same flight
Pick a cell in the table to see every offer for those dates: the same flights from everyone who sells them, cheapest first. The gap for identical seats can be large: on a flight to Milan two sellers asked $129.97 and $146.99 for the same seats. You buy the ticket on the seller’s own site.
Separate tickets, clearly marked
A self-transfer, different airlines out and back, two one-way tickets instead of a return: each case is marked right at the price. Each ticket has its own seller and link.
A shortlist
Mark the options you’re choosing between and save them in a shortlist. The prices stay as they were when you chose. Print the shortlist or send it to someone.

We compare, we do not sell

OnceOver does not sell tickets and adds nothing to the price. The prices of airlines, low-cost ones included, and of ticket sellers stand in one table: one and the same flight can have more than ten of them, each with its own price.

No need to open the sites one by one: you see at once who is cheaper. You buy from the one you chose, on their site, at their price.

Routes with the most collected dates

We count prices only: no addresses, no accounts, nothing about who searched for what. A route with fewer than 5 collected dates is not named.

Routes with our prices

For each of them, a table of prices for the dates ahead: which pair of dates is cheaper.

Search is open without signing up

Enter a route and dates and see the prices we have already collected, without an account. An account is needed only to check prices again.

Quick search and Detailed search

Quick search gives a short answer for your dates. Detailed search shows the whole table of dates, filters and sellers. The switch is at the top of the search page.

Route pages with prices by date

The Routes section lists routes with prices for dates still ahead. Each page shows the date pairs we collected, the cheapest of them and how far apart the sellers of one flight are.

Who it’s for

  • Travellers whose dates can shift by a few days while one condition can’t: a connection they will surely make, a convenient airport or a budget.
  • Anyone tired of running the same search in ten tabs who wants to see every option at once.
  • Families and groups: the price covers all the passengers you entered at once, for example two adults and a child.

How it works

  1. Enter the route

    Where you fly from and to. Before you pick any dates, you see whether there are direct flights and which cities have connecting flights.

  2. Pick your dates

    A few days to leave and a few to come back, for example 12 to 15 November and 19 to 22. The table shows a price for each of the 16 date pairs.

  3. Set your filters

    Layover length, number of stops, airlines, departure time, airports. The table updates at once, no new search needed.

  4. Open the dates you like

    A cell holds every offer for those dates: where to buy it and the date each price is valid for.

  5. Buy from the seller

    OnceOver doesn’t sell tickets. Follow our link and buy on the seller’s or the airline’s own site.
