Cheap Flight Ticket from London to Paris: How I Keep Doing It for Under £30

I’ll be real with you — the first time I booked a flight from London to Paris, I spent £180 and felt pretty good about myself. My friend called me out about an hour later. She’d just grabbed the same route for £23. I wanted to disappear into the Thames.

That was years ago, and since then I’ve probably made this trip more times than I can count. Paris is kind of my “reset” city — the place I go when I need a weekend that feels indulgent but doesn’t have to cost a fortune. And trust me, once you know how this route actually works, overpaying for it feels genuinely criminal.

So let’s talk about cheap flight tickets from London to Paris, because this is honestly one of the most misunderstood routes in all of budget travel.

The Cheap Flight Ticket from London to Paris Mistake Almost Everyone Makes

Here’s the thing nobody tells you upfront: the London-to-Paris route has so many options that people get overwhelmed and just… pick whatever pops up first on Google Flights. That’s how you end up paying £150 for a 50-minute flight.

The route is served by budget carriers like easyJet and Vueling, and they’re constantly competing for your money. Prices fluctuate wildly depending on the day, the time, and honestly sometimes what feels like the phase of the moon. I’ve seen the same easyJet flight go from £19 to £210 within a 48-hour window. No joke.

The real mistake is thinking of this as a “standard” flight and booking it like one. It’s not. This is a short-haul budget corridor, and it plays by totally different rules.

When Cheap Flight Tickets from London to Paris Actually Show Up

Timing is everything here, and I don’t mean that in a vague, unhelpful way. Let me get specific.

Tuesday and Wednesday departures are almost always cheaper than Friday or Sunday — sometimes by £40 to £60 on the same airline. If you have any flexibility at all in your travel dates, even shifting by a single day can be the difference between a great deal and an overpriced one.

Early morning flights (think 6am, the ones that require a 4am alarm) tend to be significantly cheaper. I once grabbed a 6:05am easyJet departure from Gatwick for £14. Fourteen pounds. I was exhausted on that flight but also extremely smug about it.

In terms of how far in advance to book — for this route, somewhere between 4 to 8 weeks out tends to hit the sweet spot for cheap flight tickets from London to Paris. Book too early and you’re often paying a premium before the sales kick in. Book the week before and you’re gambling with prices that have usually spiked.

London Has Multiple Airports and It Actually Matters

This is where people get tripped up. “London” can mean Heathrow, Gatwick, Stansted, Luton, or Southend — and they are not all created equal when it comes to Paris flights.

Gatwick tends to have the most frequent budget options to Paris Charles de Gaulle, and easyJet operates a lot of those flights. Stansted is worth checking for Vueling and occasional Ryanair deals, though Ryanair sometimes flies to Beauvais instead of CDG — and Beauvais is technically in a different region. Like, it’s not Paris. It’s an hour and a half from Paris. I learned this the slightly hard way during my second year of traveling, and the €17 bus from Beauvais to Paris felt a lot less charming after a delayed flight.

Always check which Paris airport you’re actually flying into before you book. CDG is the main one, Orly is closer to the city center and fine, Beauvais is only acceptable if the price difference is genuinely massive and you’ve budgeted the transfer time.

The Tools That Actually Help You Find Cheap London to Paris Flights

Google Flights is your starting point, not your ending point. Use it to get a feel for price ranges and check the calendar view — that grid of dates showing prices across a whole month is incredibly useful for spotting the cheaper days at a glance.

Skyscanner is my personal favorite for this route because their “cheapest month” search feature is genuinely good. You can type in your origin and destination, select “cheapest month,” and it’ll show you which weeks are looking favorable. That’s how I planned a spontaneous Paris weekend last spring for £26 return.

For alerts, I use Google Flights price tracking on the specific dates I’m considering. Once I’ve narrowed down roughly when I want to go, I’ll set an alert and just wait a few days to see if prices shift. Sometimes they drop, sometimes they spike — but at least you’re not going in blind.

One thing worth knowing: Kayak and Momondo sometimes surface slightly different fare combinations, especially if you’re open to mixing airlines for outbound and return. Worth a quick check once you’ve found a baseline price elsewhere.

Don’t Sleep on the Eurostar Question (Seriously)

Okay, this is technically not a flight tip, but I’d be doing you a disservice if I didn’t mention it. The Eurostar from London St Pancras to Paris Gare du Nord takes around 2 hours 15 minutes, city center to city center — no airport faff, no security theater, no bag restrictions that charge you extra for carrying a full-size shampoo.

When Eurostar has sales, you can find tickets from £29 each way. Not always, and not reliably, but it happens. And when you factor in getting to and from airports (a Gatwick Express return is about £35 by itself), the total cost comparison sometimes makes the train genuinely competitive with flying.

I’m not saying skip the flight every time. I’m saying run the numbers properly. The cheap flight ticket from London to Paris that costs £22 can quietly become £70 once you add airport transfers both ways, a checked bag, and a €4 bottle of water you definitely didn’t need but bought anyway because airports do that to you.

The Bag Situation — Because Budget Airlines Will Get You Here

easyJet, Vueling, and most budget carriers on this route have strict hand luggage policies, and this is where casual travelers get stung. A lot of fares include only a small personal item (under-seat bag) and charge separately for a cabin bag.

If you’re packing for a weekend, a 40L backpack that fits in the overhead bin is your best friend. I’ve done Paris long weekends with a 35L pack and come back with cheese, wine, and a scarf I didn’t need but absolutely don’t regret. It’s doable. If you need a bigger bag, build that cost into your price comparison from the start — don’t discover it at checkout.

You Can Absolutely Do This Trip Cheaply — Here’s the Move

Cheap flight tickets from London to Paris are genuinely available, pretty regularly, if you know what you’re looking for. The combination of flexible dates, setting price alerts a month or two out, checking your departure airport options, and actually doing the math on total trip cost (not just the headline fare) is what separates the people who brag about £20 flights and the people who end up confused about why their “budget” trip cost more than expected.

Paris doesn’t have to be the expensive European capital its reputation suggests — especially when you’re getting there for less than the cost of a nice dinner. If you’ve been putting off the trip because of flight prices, hopefully this gives you a realistic starting point.

Go find your cheap fare. Then eat a proper croissant and feel very good about yourself.
