Cheap Flights from London to Rome: Fares from £21 (2026)

Cheap Flights from London to Rome, Starting at £21

You can be standing in front of the Colosseum this weekend for less than the price of a London theatre ticket. Cheap flights from London to Rome start at just £21 one-way, and in the quiet months a midweek return for under £50 is genuinely on the table. The catch is knowing where to look and when to book, because the same seat can cost £21 or £150 depending on the date you choose.

This is one of the most fiercely contested routes in Europe. Six London airports and two Rome airports, with Ryanair, Wizz Air, easyJet, British Airways and ITA Airways all scrapping for your booking. That competition is your edge. Below you will find the exact cheapest months, an airline-by-airline price table, the airport that saves you the most, and live tools to lock in a London to Rome fare before it climbs.

Start by checking live prices for your dates, then read on to find the cheapest possible combination of airport, airline and day.

Best Time to Fly from London to Rome

Pick the right month and you fly for the price of two pizzas. Pick the wrong week and you pay triple. Here is the month-by-month picture for the cheapest London to Rome airfare.

The pattern is clear. January and November are the bargain twins, while October and September give you the best mix of low prices and good weather. Fly 1-15 December and you get near-winter fares before the Christmas surge hits.

London to Rome Airlines Compared

Five carriers do the heavy lifting on this route, each with a different trade-off between price and comfort.

Ryanair

Ryanair is almost always the cheapest, with flash-sale fares as low as £15 from Stansted into both Ciampino and Fiumicino. The honest trade-off is baggage: only a small personal bag is free, and a cabin bag or hold luggage costs extra. Pack into a backpack and nobody beats it.

Wizz Air

Wizz Air flies Luton to Fiumicino at £20 to £40 one-way. The pricing model mirrors Ryanair’s, so add-ons stack up fast. Wizz Priority bundles a cabin bag plus boarding and is worth it the moment you need more than a personal item.

easyJet

easyJet runs Gatwick to Fiumicino from around £30 to £50, but a larger cabin bag is included in the base fare, which narrows the gap with Ryanair once you add Ryanair’s bag fee. Gatwick is also far easier to reach if you live south of the Thames.

British Airways and ITA Airways

Both fly Heathrow to Fiumicino from roughly £60 with a checked bag, seat selection and refreshments included. BA earns you Avios; ITA is the smart pick if you are connecting onward to Sicily, Sardinia or the wider Mediterranean through its Fiumicino hub. Sale fares occasionally dip below £50.

Which London Airport Saves You the Most?

Your departure airport changes the total cost more than the headline fare suggests, because the train to Stansted can wipe out the saving over Heathrow.

London Stansted (STN)

Best for the lowest Ryanair fares. The Stansted Express from Liverpool Street takes 47 minutes (about £20 to £28 return booked ahead), while National Express coaches run £10 to £16 return. It is the furthest major airport from the centre, so factor the journey in.

London Luton (LTN)

Best for Wizz Air. Thameslink to Luton Airport Parkway takes 25 to 40 minutes (£15 to £20 return) plus a shuttle bus to the terminal, which adds a little time and cost.

London Gatwick (LGW)

Best for easyJet and a balance of price and ease. Gatwick Express from Victoria is 30 minutes (£20 to £32 return), or take cheaper Southern and Thameslink services. Check whether you depart from North or South Terminal.

London Heathrow (LHR)

Best for British Airways and ITA. The Elizabeth Line is the value pick at around £13 in 30 to 40 minutes; the Heathrow Express is faster but pricier.

The real door-to-door maths

A £21 Ryanair fare from Stansted, plus a £25 Stansted Express, plus a £20 cabin bag, totals £66. A £60 BA fare from Heathrow, plus £13 on the Elizabeth Line with a bag included, totals £73. The gap is far smaller than the headline £21 versus £60 suggests, so always add it all up.

Seven Ways to Pay Less for London to Rome Flights

1. Be flexible on your London airport and compare all four in one flight search. The same dates can vary by £40 between Stansted and Heathrow.
2. Fly midweek. Tuesday, Wednesday and Saturday departures beat Friday and Sunday by £15 to £30 each way.
3. Set price alerts. Flash sales on this route last 24 to 48 hours and cut fares 40 to 60 percent.
4. Book six to ten weeks ahead, or ten to twelve for Easter, summer and Christmas.
5. Travel with carry-on only. A checked bag costs £20 to £40 each way and you rarely need one for a long weekend.
6. Consider an indirect flight via Dublin or Milan in peak season for surprise savings.
7. Mix airlines: a Ryanair outbound from Stansted plus an easyJet return into Gatwick often saves £20 to £40.

Get online the moment you land

Italian airport SIM queues are long and pricey roaming charges add up fast. A travel eSIM gives you maps, restaurant reviews and ride-hailing the second your plane touches down at Fiumicino, so you walk off the jet bridge already connected.

Frequently Asked Questions

What is the cheapest month to fly from London to Rome?

January and November are the cheapest, with one-way Ryanair and Wizz Air fares regularly £21 to £30. Demand collapses after the Christmas holidays and again in late autumn, so prices follow. Skip the Christmas and Easter weeks to avoid sharp spikes.

How long is the flight from London to Rome?

A direct flight runs about 2 hours and 30 minutes. Stansted to Ciampino is the quickest at roughly 2 hours 25 minutes, while Heathrow to Fiumicino is closer to 2 hours 35 minutes.

Which London airport is cheapest for Rome flights?

Stansted usually has the lowest headline fares on Ryanair, with Luton a close second on Wizz Air. That said, always add transfers and bag fees, because a £60 BA fare from Heathrow with a free bag and a cheap Elizabeth Line ride can land within a few pounds of a Stansted budget fare.

Should I fly to Fiumicino or Ciampino airport in Rome?

Fiumicino (FCO) wins for transport, thanks to the Leonardo Express train to Roma Termini in 32 minutes for about 14 euros, and it handles late-night arrivals and onward connections better. Ciampino (CIA) is closer to the city but depends on slower buses, though it often has the cheapest Ryanair fares.

When should I book London to Rome flights?

Book six to ten weeks before departure for the best prices. For Easter, summer and Christmas, stretch that to ten to twelve weeks. Set up price alerts, as flash sales on this competitive corridor can cut fares by 40 to 60 percent overnight.

Can I get a return flight from London to Rome for under £50?

Yes, especially January, February and November. Fly midweek with hand luggage only and mix carriers, for example a Ryanair outbound and an easyJet return, and a sub-£50 round trip is realistic. Add price alerts so you pounce the moment a sale lands.
