Cheap Flights from London to Rome: Everything You Need to Know
London to Rome is one of Europe’s most popular air routes, and for good reason. The Eternal City draws millions of visitors every year with its ancient ruins, world-class cuisine, and incomparable street life. The good news for budget-conscious travellers is that fierce competition between airlines keeps prices remarkably low on this corridor. One-way fares regularly dip below £25, and if you time your booking right you can find return flights for under £50.
With six London airports and two major Rome airports serving this route, there is no shortage of options. Budget carriers like Ryanair and Wizz Air battle it out alongside full-service airlines such as British Airways, ITA Airways, and easyJet. That competition is your advantage. In this guide, we break down exactly when to fly, which airline to choose, which airports make the most sense, and how to lock in the lowest possible price for your London to Rome trip in 2026.
Current Prices for London to Rome Flights
As a general benchmark, expect £21-£45 one-way on budget carriers during off-peak months, and £60-£150 during summer. Full-service airlines run £80-£200, though sales can bring those figures down. Use the tool below to compare live prices for your dates.
Best Time to Fly from London to Rome
Choosing the right month can mean the difference between a £21 fare and a £150 one. Here is a month-by-month breakdown to help you plan.
January and February
The cheapest months to fly. Rome is cool but pleasant (10-13 degrees Celsius), tourist crowds are thin, and one-way fares on Ryanair and Wizz Air frequently drop to £21-£30. Hotel prices hit their annual low too, making this the best window for a genuinely cheap city break.
March and April
Prices climb as Easter approaches. Expect one-way fares of £30-£60. Late March still offers bargains, but Easter week sees a significant spike. Fly midweek in early March for near-winter pricing with warmer weather.
May and June
Prime visiting season with ideal weather. One-way fares range from £45-£90. June pushes higher during half-term school holidays. Book at least eight weeks ahead for this period.
July and August
Peak summer brings fares of £70-£150 one-way. Rome regularly exceeds 35 degrees Celsius. Mid-August can soften hotel prices slightly as Romans head to the coast, but airfares stay high.
September and October
Shoulder season delivers excellent weather with falling prices. September fares hover around £40-£70; October drops to £30-£55. Many experienced travellers consider this the best window to visit.
November and December
November is the bargain hunter’s sweet spot at £21-£30 one-way. Early December is similarly cheap, but fares spike sharply for Christmas and New Year. Fly between 1-15 December for some of the year’s best deals.
Airlines Operating the London to Rome Route
Several airlines compete on this route, each with distinct strengths.
Ryanair
Ryanair is typically the cheapest option, with one-way fares starting as low as £15 during flash sales. They operate from London Stansted (STN) to Rome Ciampino (CIA) and Rome Fiumicino (FCO). Multiple daily frequencies mean flexible scheduling. The trade-off is a strict baggage policy — a small personal bag is included free, but cabin bags and checked luggage cost extra. If you pack light, Ryanair is hard to beat on price.
Wizz Air
Wizz Air flies from London Luton (LTN) to Rome Fiumicino (FCO). Fares are competitive with Ryanair, often in the £20-£40 range one-way. Wizz Air’s pricing model is similar to Ryanair’s, with add-ons for baggage and seat selection. Their Wizz Priority product, which includes a cabin bag and priority boarding, can be good value if you need more than just a personal item.
easyJet
easyJet operates from London Gatwick (LGW) to Rome Fiumicino (FCO). Fares are slightly higher than Ryanair and Wizz Air, typically starting around £30-£50 one-way, but easyJet includes a larger cabin bag in the base fare. Gatwick is also more convenient than Stansted or Luton for many Londoners, particularly those south of the Thames. easyJet’s frequency on this route is excellent, with multiple departures daily.
British Airways
British Airways flies from London Heathrow (LHR) to Rome Fiumicino (FCO) several times daily. Fares start around £60-£80 one-way in economy, but you get a more inclusive product: a checked bag, seat selection, and complimentary snacks and drinks. For business travellers or anyone who values the Heathrow experience and Avios points, BA is a strong choice. Sale fares occasionally dip below £50.
ITA Airways
Italy’s national carrier flies from Heathrow (LHR) to Fiumicino (FCO) at prices similar to BA, with checked baggage and meals included. Particularly worth considering if you are connecting onward to other Italian or Mediterranean destinations via their Fiumicino hub.
Vueling
Vueling runs seasonal services from London Gatwick (LGW) to Rome Fiumicino (FCO) during peak summer months, with fares competitive with easyJet.
Which London Airport Should You Choose?
Your departure airport has a bigger impact on total cost than you might expect.
London Stansted (STN)
Best for: Lowest headline fares via Ryanair. Getting there: Stansted Express from Liverpool Street (47 minutes, around £20-£28 return if booked in advance). National Express coaches are cheaper at £10-£16 return. Watch out for: Stansted is the furthest major airport from central London. Factor in travel time and cost when comparing against slightly pricier flights from closer airports.
London Luton (LTN)
Best for: Wizz Air’s competitive fares. Getting there: Thameslink train to Luton Airport Parkway (25-40 minutes from central London, around £15-£20 return), plus a shuttle bus to the terminal. Watch out for: The shuttle bus adds time and a small additional cost. Luton’s terminal can feel cramped during peak periods.
London Gatwick (LGW)
Best for: easyJet flights with a balance of price and convenience. Getting there: Gatwick Express from Victoria (30 minutes, around £20-£32 return) or Southern/Thameslink trains for less. Watch out for: Check whether your flight departs from the North or South Terminal to avoid a last-minute shuttle transfer.
London Heathrow (LHR)
Best for: Full-service flights on British Airways and ITA Airways. Getting there: The Elizabeth Line offers the best value at around £13 from central London, taking 30-40 minutes. The Heathrow Express is faster (15 minutes from Paddington) but pricier. Watch out for: Heathrow flights cost more, but cheaper transport and included baggage on BA narrow the total trip cost gap.
The Bottom Line on Airports
Always calculate the full door-to-door cost. A £21 Ryanair fare from Stansted plus a £25 Stansted Express ticket plus a £20 cabin bag add-on totals £66. A £60 BA fare from Heathrow plus a £13 Elizabeth Line ride with included baggage totals £73. The gap is often smaller than headline fares suggest.

Money-Saving Tips for London to Rome Flights
1. Be Flexible with Your Departure Airport
As outlined above, checking all four major London airports can reveal dramatically different prices for the same travel dates. Use a multi-airport search to compare them side by side.
2. Fly Midweek
Tuesday, Wednesday, and Saturday departures are consistently cheaper than Friday and Sunday flights. Shifting your trip by even one day can save £15-£30 each way.
3. Set Up Price Alerts
This route sees frequent flash sales, especially from Ryanair and Wizz Air. Set up alerts on multiple comparison sites so you are notified the moment prices drop. These sales often last only 24-48 hours.
4. Book 6-10 Weeks in Advance
Data consistently shows that the sweet spot for European short-haul flights is six to ten weeks before departure. Booking too early means airlines have not yet started competing on price; booking too late means only expensive seats remain.
5. Travel with Carry-On Only
Budget airline fares look cheap until you add baggage. A checked bag on Ryanair or Wizz Air can cost £20-£40 each way. Pack into a personal item or small cabin bag to keep the total cost low. Rome is a city break destination — you probably do not need a full suitcase for a long weekend.
6. Consider Indirect Flights for Deep Discounts
Connecting flights through hubs like Dublin, Barcelona, or Milan can sometimes undercut direct services during peak season. The journey takes longer, but the savings can be significant.
7. Mix and Match Airlines
There is no rule saying you must fly the same airline both ways. Book the cheapest outbound with Ryanair from Stansted and the cheapest return with easyJet into Gatwick. This approach frequently saves £20-£40 on the round trip.
