Best UK Flight Deals in March 2026: From £31 to Tokyo

After the January slump, finding a flight under £50 to anywhere sunny feels like winning something. March is consistently one of the cheapest months to fly from the UK, with airlines still pricing aggressively after the half-term rush fades in late February.

School holidays don't kick in until late March, which means the first three weeks are genuinely quiet. Planes are less full, prices drop, and hotels that were rammed in February are suddenly bookable for a Tuesday check-in without a premium.

The weather argument is stronger than people give it credit for. Southern Europe sits in the mid-to-high teens by mid-March, occasionally nudging 20 degrees in Spain and Portugal. That's not beach weather, but it's absolutely city-break weather, and honestly preferable to sweating through Seville in August.

Booking 3-6 weeks out in March tends to work unusually well. Airlines haven't sold out, demand isn't surging, and the sweet spot for Ryanair and easyJet pricing often sits in that window. Set a price alert, check Tuesday and Wednesday departures, and you'll usually find something worth jumping on.

Seville from £39 one-way on Ryanair from Stansted is the one to beat in March. Mid-month temperatures sit around 19-21 degrees, the orange blossom is out, and crowds are nothing like Easter week. My mate booked a long weekend last March for under £290 total including a central flat.

Lisbon from £44 one-way on easyJet from Gatwick is close behind. TAP Air Portugal also flies from Heathrow from around £67 one-way if Gatwick doesn't work for you. March in Lisbon is mild, occasionally rainy, but the city genuinely doesn't care and neither should you.

Porto from £41 one-way on Ryanair from Stansted or £48 from Bristol on Ryanair is the one worth checking mid-week. Three nights there in March can come in under £300 all-in if you stay slightly east of the centre. The food alone justifies the 6am departure.

Prague from £31 one-way on Wizz Air from Luton is still one of the cheapest flights in Europe in March. It'll be cold, around 6-10 degrees, so pack properly. Returns from £62 are realistic, and a long weekend in Prague for under £250 all-in is completely doable if you stay in a hostel or a cheap guesthouse near Žižkov.

Worth also checking Ryanair from Edinburgh to Alicante from £35 one-way for a March sun fix without the London airport stress. Jet2 fly from Manchester to Malaga from around £58 one-way, which is solid value for a direct flight from the North.

Marrakech from £67 one-way on easyJet from Gatwick is a proper deal for a four-hour flight. March temperatures in Morocco hover around 20-22 degrees, which is genuinely warm, and the souks are far less chaotic than peak summer. I did four nights there in March 2024 for under £420 including flights and a riad, which felt like a result.

Casablanca from £79 one-way on Royal Air Maroc from Heathrow is worth knowing about if you want to combine cities. The train between Casablanca and Marrakech runs for a few pounds and takes around two and a half hours. It's an underused route combination for UK travellers.

Amman, Jordan, from £189 one-way on Royal Jordanian from Heathrow sounds steep until you factor in what March gets you. Petra in March is uncrowded and around 18 degrees, which is ideal for walking. Returns on Turkish Airlines via Istanbul from Heathrow can dip to £310, which for a trip to Petra and Wadi Rum is genuinely good value.

Tokyo from £489 return on Japan Airlines from Heathrow is the big one. March is cherry blossom season, which means crowds, yes, but also one of the best times to visit the country. Check British Airways from Heathrow too, where I've seen March returns dip to £520. Book six weeks out minimum, not three, as Tokyo in blossom season fills up fast.

Ryanair and Wizz Air are doing the heavy lifting for cheap March flights right now. Ryanair from Stansted to Seville, Porto, Faro, and Palma regularly prices under £45 one-way in March when you book 4-5 weeks ahead. Wizz Air from Luton to Bucharest from £29 and Sofia from £33 are also worth knowing if you're flexible on destination.

easyJet is the one to watch from Gatwick, Bristol, and Manchester for slightly more comfortable short-haul. easyJet from Bristol to Amsterdam from £38 one-way and from Manchester to Nice from £52 one-way are both solid March options. The bag fees sting if you're not careful, so factor in £13-£23 for a cabin bag if you're travelling with more than a small rucksack.

For longer haul, Turkish Airlines from Manchester and Heathrow consistently undercuts the competition on routes to the Middle East and Asia. Istanbul from Manchester on Turkish Airlines from £149 return is a regular feature in March, and using Istanbul as a stopover to Amman or Tokyo adds surprisingly little cost if you book the through-ticket.

The 3-6 week booking window works in March because most people have already planned their spring half-term trips and booked ahead for Easter. The gap between those two travel peaks is where airlines quietly drop prices to fill seats. Check prices on a Tuesday morning, clear your cookies or use incognito mode, and avoid the Sunday evening browse when everyone else is looking.
