In 2026, the average round-trip transatlantic flight in the first two weeks of March cost around $490. The same routes in the last week of March — Spring Break — ran $720. Same airline. Same destination. A $230 difference based purely on which week you travel.
March is genuinely one of the cheapest months to fly. But it is not uniformly cheap. There is a predictable spike embedded inside it, and most people book straight into it without realising.
This guide covers why prices drop, which destinations see the biggest discounts, how to find real deals using specific tools, and when budget carriers are worth the gamble.
Why March Flights Drop in Price — But Only for Specific Weeks
Airlines price seats based on demand. Demand in early-to-mid March is genuinely low. January and February travelers have gone home. Holiday trips are over. The summer rush does not start until late April, when bookings begin to fill aircraft heading into June and July. That gap — roughly March 1 through March 10, and again March 17 through March 22 in most years — is where airlines quietly discount to fill planes.
The mechanism is not a sale. Airlines do not announce March deals. What happens is that dynamic pricing algorithms drop fares automatically when seats are not selling. A flight from New York to Rome that sat at $780 in January might slip to $510 by late February if bookings are thin. That is how revenue management systems work.
For European routes specifically, March is the deepest shoulder-season window available. Summer fares start climbing by late March as summer-booking season accelerates. If you are flying from North America or the UK to Mediterranean destinations, the first three weeks of March often represent the annual low point for airfare.
What Airlines Are Actually Doing in March
Carriers like Turkish Airlines and Iberia run their most aggressive transatlantic promotions in late January and February, targeting March departures. These are not flash sales — they are deliberate attempts to move inventory during historically soft demand. Turkish Airlines uses Istanbul as a connecting hub and consistently prices March transatlantic routes $100–150 below comparable Delta or United fares for the same travel dates.
Low-cost carriers in Europe — Ryanair and easyJet — also discount heavily in early and mid-March. Ryanair’s intra-European fares in this window regularly hit €19–39 one-way on routes like London Stansted to Lisbon or Dublin to Barcelona. easyJet’s off-peak pricing kicks in for the same period, dropping London Gatwick to Amsterdam under £30 on certain dates.
The One Exception: Destinations With Their Own Peak Season
Not every destination gets cheaper in March. Japan during cherry blossom season — typically late March to mid-April — sees flight prices spike 40–60% above January levels. Flights to India during Holi week, which falls in March, cost more, not less. The cheap-March rule applies to most of Europe, North Africa, and domestic US routes. It does not apply globally.
The Spring Break Problem
Spring Break is the single biggest pricing trap in March. Most US college Spring Breaks run March 8–22, with the heaviest travel falling March 13–21. Prices on popular leisure routes — Florida, Mexico, Caribbean, Las Vegas — spike 30–60% in that window. Book outside those dates and you are in the cheap zone. Book into them and you are paying near-summer prices.
| March Week | Typical Price Impact | Best Routes |
|---|---|---|
| March 1–7 | Lowest fares of the month | Europe, North Africa, domestic US |
| March 8–14 | Mixed — early Spring Break begins | International still reasonable; avoid Florida/Caribbean |
| March 15–22 | Peak Spring Break — prices spike | Worst week for domestic US and beach destinations |
| March 23–31 | Prices normalise; Easter can affect this | Check Easter dates — they shift every year |
If your dates are flexible, March 1–7 is consistently the cheapest week of the entire month. Book this window and you will typically pay 15–25% less than the monthly average on most routes.
Where Flights Get Cheap in March: Destination Breakdown
Not every route discounts equally. Here is where the real savings show up — with fare ranges based on 2026 pricing data pulled from Google Flights and Skyscanner searches.
| Destination | Flying From | Avg March Fare (RT) | Why It’s Cheap |
|---|---|---|---|
| Lisbon, Portugal | New York (JFK) | $420–550 | Off-peak before summer; TAP Air Portugal often discounts |
| Barcelona, Spain | London (LGW) | £60–110 | easyJet base route, low March demand |
| Marrakech, Morocco | London (STN) | £80–140 | Ryanair route; ideal weather; pre-tourist-season |
| Bangkok, Thailand | London (LHR) | £380–520 | End of dry season; fewer bookings than December |
| New Orleans, USA | Chicago (ORD) | $120–200 | Post-Mardi Gras lull; Southwest frequently drops fares |
| Mexico City, Mexico | Los Angeles (LAX) | $180–280 | Not a Spring Break hotspot; Aeromexico competes aggressively |
| Nairobi, Kenya | London (LHR) | £480–640 | Shoulder season; Kenya Airways and Turkish Airlines compete |
Best value in March overall: Lisbon from North America and Morocco from the UK. Lisbon offers full infrastructure, English widely spoken, and excellent March weather at 17–19°C. Morocco from London Stansted on Ryanair regularly hits sub-£100 return — hard to beat for a long weekend.
Mexico City from the US West Coast is consistently underrated. It does not attract the Spring Break crowd that Cancun does, so fares stay suppressed through the whole month.
How to Find Cheap March Fares Before They Disappear
Five steps. Do them in this order.
- Start with Google Flights’ price grid. Go to flights.google.com, enter your origin, leave destination blank or enter a region like Europe, and switch to the flexible dates calendar view. You will see a colour-coded map showing the cheapest days to fly. This is the fastest way to identify which specific March dates are cheapest without manually checking 30 combinations.
- Set a fare alert and stop manually checking. Use Hopper (iOS and Android, free) or Google Flights’ built-in price alerts. Hopper’s Price Freeze feature — $1–10 depending on route — lets you lock in a fare for 14 days while you decide. Genuinely useful for March trips where you want to commit but are not 100% certain on dates.
- Check Skyscanner’s Everywhere search. skyscanner.net lets you set destination to Everywhere and sort by price. In early-to-mid March this view regularly surfaces flights to Lisbon, Porto, Marrakech, and Southern Spain under $300 from major US cities. Skyscanner is better than Google Flights for catching Ryanair and easyJet fares that do not always appear in Google’s results.
- Prioritise Tuesday and Wednesday departures. For domestic US routes, these days are consistently $20–50 cheaper than Friday or Sunday. The effect is smaller on international routes but still worth checking before you lock dates in.
- Do not book more than 10 weeks out. The sweet spot for March flights is 6–10 weeks before departure — roughly January through mid-February. Booking in December is often counterproductive. Airlines are still riding holiday-season demand signals and fares have not dropped yet. Booking in late February works for most economy routes but premium seats fill faster.
One thing that does not work: clearing your browser cache or searching in incognito mode to reset prices. Flight pricing is server-side, not stored in your cookies. Airlines do not raise prices based on your search history. This myth has been debunked multiple times — Skyscanner’s own data team confirmed it years ago. It wastes your time.
Budget Carriers in March: When Ryanair or Frontier Is Actually Worth It
Budget airlines make sense in March under three conditions: the route is direct point-to-point with no connection, your bag fits under the seat or you are willing to pay the fee, and the price difference versus a full-service airline exceeds £60 or $80 after all fees are added.
In Europe, Ryanair is genuinely competitive in March on routes like London–Seville, Dublin–Faro, and Brussels–Marrakech. Fares of €25–50 one-way are real. But you pay €10–25 extra for a checked bag and another €5–15 to choose a seat. A “£29 fare” can realistically cost £75–90 after bags and seat selection. That is still often cheaper than British Airways for the same route, but run the numbers before you book.
When to Skip the Budget Carrier Entirely
For transatlantic March routes, Turkish Airlines routinely beats both budget carriers and legacy carriers on price, while offering a full-service product with free checked bags and meals included. A New York to Barcelona round-trip via Istanbul in early March 2026 was available for $480 — full-service, one checked bag, not a budget product. That is hard to justify skipping for a Ryanair connection.
For US domestic travel, Southwest Airlines is worth a dedicated check specifically because of their no-change-fee, two-free-bags policy. A Frontier or Spirit fare might look $40 cheaper on the results page. After a 35lb checked bag ($65 on Spirit) and a seat assignment ($15–25 on Frontier), Southwest’s fare is usually the better deal. March is also when Southwest runs its semi-annual sale, which historically appears in late January targeting March departure dates.
The Spirit Airlines Verdict in March
Spirit makes financial sense on exactly one type of March trip: a carry-on-only domestic flight under three hours where a delay would not ruin your plans. Spirit’s on-time performance historically runs below 70%. In March, weather-related disruptions are common. If a missed connection or a four-hour tarmac delay would destroy your trip, pay the extra $50 and fly someone else.
March Flight Questions: Direct Answers
Is March actually a cheap month to fly?
Yes. It is one of the five cheapest months of the year for air travel, alongside January, February, September, and November. Avoid Spring Break dates — roughly March 13–21 for most US markets — and you get genuine discounts on the majority of routes.
How far ahead should I book March flights?
Six to ten weeks out for most routes, meaning January to early February. International long-haul benefits from slightly earlier booking — eight to twelve weeks — for better seat selection. Domestic US routes are more forgiving; four to six weeks out is usually fine, and sometimes cheaper than booking earlier.
What is the cheapest two-stop Europe strategy for March?
Fly transatlantic into London, Lisbon, or Dublin — consistently the three cheapest transatlantic entry points — then take a budget intra-European carrier to your final destination. A New York to Seville itinerary might run $450 transatlantic to London and £35 Ryanair to Seville, totalling around $490. Flying New York directly to Seville on Iberia in March runs $650–780. The two-stop approach saves $150–300 and is worth it if you are traveling with carry-on only luggage.
Does the day of the week matter for March fares?
For domestic US routes: yes. Tuesday and Wednesday departures save $15–50 on average versus Friday or Sunday. For international routes, the effect is smaller, but Saturday departures are consistently more expensive than Tuesday through Thursday on transatlantic routes. If you have flexibility, avoid Saturday and Sunday travel on any route in March.
