Train seat or boarding pass — the real London–Paris fork
Eurostar from St Pancras drops you at Gare du Nord with one bag and no security theatre — unbeatable for Marais or République hotels if you live north of the river. Flying wins on schedule choice and from addresses far from King's Cross; a cheap Stansted ticket can erase its saving if you cross London twice before you even reach Paris.
Compare door-to-door time, not romance: a 7 a.m. flight from Luton with two bags rarely beats an 8 a.m. train with a croissant at the buffet car.
Flying vs Eurostar — door-to-door
| Factor | Flying | Eurostar |
|---|---|---|
| Typical centre-to-centre time | Often 3.5–5 hours+ once airports and transfers are in | Often about 2.5–3.5 hours St Pancras ↔ Gare du Nord |
| Best when | You live far from King’s Cross, or need a specific flight time | Light bags; hotel near Marais, République or northern Paris |
| Baggage | Basic fares often charge for cabin bags and seats | Standard tickets are usually more luggage-friendly |
| Weak when | Late landing + far airport + two hold bags | Heavy luggage; living far south or west of central London |
| How to decide | Price the flight with bags, then add Express/coach both ends | Compare total time and arrival station to your hotel pin |
Leaving London — which airport matches your postcode
Heathrow suits full-service connections and west London bases. Gatwick feeds many short-haul leisure fares for south-east travellers. Stansted and Luton sell the lowest headlines — factor the train or coach before calling them cheap.
Friday evening queues at any airport punish short breaks; mid-week departures often pair with quieter Left Bank restaurants and easier Louvre slots.
London airports for Paris — quick compare
| Airport | Best For | Main Advantage | Main Drawback |
|---|---|---|---|
| Heathrow (LHR) | West London; full-service / connections | BA and Air France frequency to CDG | Peak security queues; fares often higher than leisure airports |
| Gatwick (LGW) | South / south-east London | Strong easyJet and leisure short-haul choice | Awkward if you live north of the river |
| Stansted (STN) | North-east London / Essex; low headlines | Often the cheapest ticket on the calendar | Express + cross-London time can wipe the saving |
| Luton (LTN) | North London / M1 corridor | Regular low-cost Paris schedules | Early starts and DART/coach hops with bags |
Airlines on London–Paris
British Airways and Air France dominate Heathrow–Charles de Gaulle — useful if you want frequency, connections or a bag-inclusive fare. easyJet and Vueling cover many Gatwick, Luton and Orly/CDG leisure schedules and usually win the headline when you travel light. Ryanair often lands at Beauvais rather than a city airport — cheap only after you price the coach. Schedules change; filter non-stop and compare bags on the live results before you pick a brand.
Arriving in Paris — CDG scale versus Orly ease
Charles de Gaulle carries the widest airline choice and RER links into central Paris — strong if you are heading to the Marais or northern arrondissements. Orly sits closer to the Left Bank and can feel faster for Montparnasse or Saint-Germain addresses if schedules align.
Late arrivals favour arrondissements with straightforward taxi ranks; dragging luggage through narrow Marais streets after midnight is a Paris initiation few travellers want.
Paris airports — CDG, Orly or Beauvais
| Airport | Best For | Transfer to Central Paris | Main Drawback |
|---|---|---|---|
| Charles de Gaulle (CDG) | Airline choice; north / east / Marais hotels | RER B roughly 35–50 minutes to central stations | Large terminals; longer walks with luggage |
| Orly (ORY) | Left Bank / south addresses; many short-haul leisure flights | Orlybus / Orlyval + RER often about 25–40 minutes | Fewer long-haul options than CDG |
| Beauvais (BVA) | Ultra-low fare only, when you have time | Coach often 1 hour 15 minutes or more, then metro | Not a city airport — weak for late arrivals and short weekends |
Airport transfers — quick guide
- Heathrow: Elizabeth line or Piccadilly into town; Heathrow Express is faster and dearer. Allow extra time at peak security before you treat it as a short hop.
- Gatwick: Gatwick Express or Thameslink into central London. Works cleanly from south London — less so if you start north of the river with bags.
- Stansted: Stansted Express to Liverpool Street, then Tube or taxi. Factor that cost and time before a “cheap” Paris fare wins.
- Luton: DART to Luton Airport Parkway, then Thameslink or East Midlands into London. Fine with a cabin bag; slower with two hold cases on an early departure.
- CDG: RER B is the usual rail link into central Paris (often about 35–50 minutes to the main stations). Late nights favour a taxi if your hotel is awkward on stairs.
- Orly: Orlybus, Orlyval + RER, or taxi depending on your arrondissement. Often feels quicker for Left Bank and southern hotels when schedules align.
- Beauvais: Coach into Paris typically 1 hour 15 minutes or more before any metro. Skip it for late arrivals into a two- or three-night break.
Seasons, fashion weeks and when fares breathe
April to June and September to October balance café terraces and museum hours without August's empty Parisian streets mixed with tourist peaks. Fashion weeks, Roland-Garros and UK school holidays tighten both seats and hotel rates.
Low-cost fares may exclude cabin bags — add bag and seat fees before comparing with Eurostar's included luggage allowance on standard tickets.
After landing — arrondissement before attraction tickets
Paris moves by arrondissement: Saint-Germain for literary cafés and walking the Seine; Marais for smaller hotels and gallery mornings; Montmartre for views but steeper climbs. Lock your base before reserving timed Louvre or Orsay entries — crossing the city twice a day eats the savings on a budget fare.
Use the Paris stays guide for neighbourhoods, then compare Paris experiences. Car hire suits Normandy or Loire extensions, not boulevard traffic inside the périphérique.
