Best Flight Deals From UK Airports in March 2027

After the January slump, finding a £39 one-way to Seville feels genuinely emotional. February deals are patchy because half the country is still skint from Christmas, but by late January the March fares start dropping and they stay low right through to mid-February if you know where to look.

March sits in that sweet spot before Easter prices detonate. Schools are still in, the half-term rush is over, and airlines are filling seats at prices they won't touch again until October. That gap is your window.

The weather angle matters too. You're not gambling on sunshine in northern Europe, but Seville, Lisbon, and Porto are regularly hitting 17-21°C in March. That's jumper weather, not beach weather, but after a British winter it feels like a different planet.

March also suits shorter trips well. A Thursday-to-Sunday city break works perfectly because mid-week fares are low and you're back before the weekend price spike on the return. Three nights is plenty for most of these cities if you actually walk around and don't spend half of it in a rooftop bar.

Seville from £39 one-way on Ryanair from Stansted is the one I keep coming back to. Mid-March temperatures sit in the low 20s, the Easter crowds haven't arrived yet, and a central flat costs half what it does in April. My mate went last March for under £290 total including flights and three nights in a decent Airbnb near the Alameda.

Lisbon from £44 one-way on easyJet from Gatwick is similarly well-priced and the city is genuinely enjoyable in the cooler months. The hills are easier to walk when it's 16°C rather than 30. TAP Air Portugal also fly from Heathrow from around £61 one-way if Gatwick doesn't work for you.

Porto from £41 one-way on Ryanair from Stansted is one of the best-value flights in Europe in March full stop. Three nights there typically comes in under £300 all-in if you avoid Saturday night. The wine, the food, the fact it's genuinely less overrun than Lisbon, all of it.

Prague from £31 one-way on Wizz Air from Luton is the cold-weather option that actually delivers. It's going to be 8-12°C, so pack properly, but Prague in March before the stag do season fully kicks off is a different city. easyJet also fly from Bristol from around £47 one-way, which suits anyone in the south-west.

Jet2 fly to Malaga from Manchester from around £52 one-way in March, which is worth a look if you're in the north and want guaranteed mild weather. The Costa del Sol is quiet, cheap, and very easy in March. Not exciting, but sometimes that's exactly what you want.

The 3-6 week window before travel is where March deals live. Unlike peak summer where you need to book months out, March fares often soften in late January and early February as airlines try to shift remaining seats. Set a price alert on Google Flights for your route and check it every few days rather than obsessing over it hourly.

Ryanair and Wizz Air are the ones to watch for the very lowest base fares, but be honest with yourself about bags. A Ryanair fare of £31 from Luton to Prague becomes £62 once you add a 10kg cabin bag. That's still decent, but factor it in before you screenshot it to your group chat.

easyJet tend to be slightly more generous with included baggage and their Gatwick and Bristol routes to Lisbon, Seville, and Porto are worth checking alongside the budget carriers. I've seen Gatwick to Lisbon on easyJet dip to £44 one-way in February for March travel, which is hard to argue with.

Midweek departures, so Tuesday or Wednesday out and Thursday or Sunday back, consistently undercut weekend fares by £15-30 each way. If your job allows any flexibility at all, that saving adds up to an extra night in a good hotel.

Marrakech from £89 one-way on easyJet from Gatwick is one of the best longer-haul punts you can make in March. Temperatures are around 20-22°C, the city is busy but not overwhelming, and a four-night trip can come in under £450 all-in if you're sensible about accommodation. Ryanair also fly from Stansted from around £79 one-way if you're willing to get up at 4am.

Amman, Jordan from £210 one-way on Royal Jordanian from Heathrow sounds steep until you price up a week there properly. Petra in March, before the summer heat and the peak crowds, is a seriously good call. Flights occasionally drop closer to £180 if you catch a sale in January. Turkish Airlines via Istanbul from Heathrow can bring it down to around £195 one-way too.

Tokyo from £420 one-way on JAL from Heathrow in March is genuinely worth considering if you've been putting it off. March is cherry blossom season, which sounds like a cliché until you're actually there and realise why everyone talks about it. Fares from Heathrow with JAL or ANA hover between £420-£560 one-way depending on how far out you book, and March demand is high, so six weeks out rather than three is the smarter call here.

Turkish Airlines from Manchester to Istanbul, then onward to Tokyo, can shave the fare down to around £390 one-way in March, which is one of the better long-haul deals going from a northern UK airport. The layover in Istanbul is usually 2-3 hours, which is fine. Two stops is a mild inconvenience when you're saving £150.
