You can fly from Amsterdam to London for under €40. You can also pay €180 for the same journey. The difference has nothing to do with which airline you trust — it’s entirely about when you search and what you assume is included in the price.
I’ve seen people book a Ryanair flight to Stansted thinking they’ve landed a bargain, then pay nearly as much again for a backpack fee and a National Express coach to Victoria. That’s not a cheap flight. That’s a budget flight that quietly became a normal-priced trip.
Five London airports — and why it matters which one you pick
Amsterdam has one airport. London has five. Heathrow (LHR), Gatwick (LGW), Stansted (STN), Luton (LTN), and London City (LCY) — and they are not equal when it comes to cost, convenience, or stress.
Stansted and Luton attract the cheapest fares because that’s where Ryanair and easyJet park most of their cheap seats. But Stansted sits 50km northeast of central London, and a Stansted Express train to Liverpool Street runs around £19 each way. Luton is barely better. Add that to a return fare and suddenly Heathrow — which costs more on the ticket — lands you on the Piccadilly Line for £5.50 into Zone 1, and often comes out cheaper total.
British Airways and KLM run Schiphol to Heathrow daily. They’re not budget carriers, but they include cabin baggage, get you to the best-connected airport, and have far shorter delays on average. For anything shorter than a week’s trip, that reliability is worth more than you’d think.
January is cheap. August is painful. Everything else is negotiable.
The Amsterdam–London route runs year-round and is busy enough that it almost never collapses into genuinely dirt-cheap fares. But there’s a clear pattern. January and February are the cheapest months — the city quiets after New Year, and flights that cost €120 in December drop to €45 in the second week of January. October and November are similarly low outside of school holidays.
The expensive periods are predictable: summer (late July through August), both Dutch and British Easter weeks, and the Christmas–New Year window. A long weekend in May or early June is also more expensive than people expect because half of Amsterdam seems to be booking the same trip. If you have any flexibility and you’re comparing dates, Tuesday and Wednesday departures save you 15–25% over Friday. That’s not a small number on a trip you might take several times a year.
The booking window people get wrong
Book too early — more than three months out — and you’ll pay a premium. Airlines hold their cheapest seats back and release them in waves. Book the morning a flight goes on sale and you’re not getting the best deal; you’re getting whatever they’ve priced to test demand.
The sweet spot on a short-haul European route like this is six to ten weeks before departure. That’s when the cheap seats still exist and the algorithm hasn’t yet started squeezing for scarcity. Closer than three weeks, prices spike fast. The exception is distressed inventory — the 48-hour window sometimes shows genuinely cheap leftover seats — but that requires you to be flexible with almost no notice, which isn’t how most people travel.
One specific tip: avoid searching on Sunday evenings. That’s when business travellers start planning the week ahead, prices tick upward, and the algorithm picks it up fast. Early Tuesday morning tends to see fresher, more competitive pricing.
What “€29 one-way” actually means in practice
The floor fares are real. EasyJet does sell Amsterdam to London for €29 one-way. Ryanair sometimes goes lower. But you need to read what that includes, because the headline fare often doesn’t cover what you assume it does.
At €29, you’re typically getting a seat and a bag that fits under the seat in front — nothing in the overhead bin. Add a standard cabin bag and you’re paying €20–35 more each way. Add hold luggage and it doubles again. If you’re going to London for three nights and can genuinely travel with a small backpack, the budget fare makes sense. If you’re bringing a rolling suitcase, factor in the fees before you click.

The trip itself: a few things worth knowing
The flight is 55 minutes. With boarding and deplaning, block around two hours door-to-door airside. You need to arrive at Schiphol about 90 minutes before a European flight — the airport is efficient but it’s also massive, and gate distances vary a lot depending on which terminal you depart from.
London border control at Stansted can be genuinely slow during peak times. Heathrow T2 and T5 are usually faster, particularly if you have an EU biometric passport — the Dutch ID card works fine at the automated gates, which are considerably faster than the staffed desks.
Don’t leave accommodation to chance. Hotels in central London are expensive and fill up fast, particularly around any major event. Shoreditch, Bermondsey, and Bethnal Green are all well-connected and noticeably cheaper than the West End or South Bank. Book at least three weeks out for anything reasonable.
