How we measured this
Fares for this route are queried once a day and stored as observations, each one with the moment it was read. The band above is the tenth, fiftieth and ninetieth percentile of those observations over a rolling ninety days, computed on integer minor units so no rounding accumulates. Observations in different currencies are never mixed into one band.
This page becomes indexable only once it holds at least 60 observations, 90 days of history and fares from 3 distinct carriers. Until then it says so, and stays out of the sitemap. The full method is published, including what the percentiles do not claim.
The next decisions
The band above answers what the flight costs. These are the things that cost money after it, and where most of a trip budget quietly goes.
- insurance
Travel insurance that pays on medical
Most claims are refused for a reason the policy stated plainly. Check the medical limit, the excess and the activity exclusions before you buy, not after.
Compare cover - esim
Data before you land
An eSIM installs before departure and connects the moment the plane doors open. Your number and your 2FA codes stay on your existing SIM.

London to Barcelona — questions
What is a good price for London to Barcelona?
Anything at or below €39.00 sits in the cheapest tenth of the fares we observed, and €54.00 is the middle of the distribution. Above €89.00 you are paying more than nine fares in ten.
Where do these prices come from?
We query fares for this route once a day and store every result with the moment we read it, the departure and return dates, the carrier and the currency. Nothing is averaged before storage and no observation is edited afterwards. The full method is on our methodology page.
Are these the prices I will pay?
No. A price here is a fare that was available at the moment we read it. Fares change constantly, so the figure you see when you follow a link may differ. We publish what we observed, with the date, and nothing more than that.
Do these figures include baggage?
No. The observed fares are return economy tickets as quoted, before checked baggage, seat selection or any other extra. On low-cost carriers that gap is often the largest single cost of the trip, so compare like with like before booking.
How far ahead should I book?
We do not publish booking-window advice on this route yet. It requires comparing the fare against the date we observed it, over many departures, and we will publish it when we have enough history to make the claim honestly rather than repeat the usual rule of thumb.
Which airlines fly this route?
We have observed fares from 4 distinct carriers on this route in the current window. Carrier mix changes by season, and a route served by more carriers usually shows a wider band.
Do I need travel insurance for this trip?
That depends on what you would lose if it went wrong, not on the destination. The two things worth checking before you buy are the medical limit and the activity exclusions, because those are what refused claims usually turn on.
Will my phone work when I land?
Usually yes, at roaming rates that can exceed the cost of the flight over a fortnight. An eSIM installed before departure connects on landing and leaves your existing number and its two-factor codes untouched on your physical SIM.
