Which London airports should you search for cheap flights?
Search the LON multi-airport code first, then isolate LHR, LGW, STN, LTN and LCY. Heathrow wins long-haul connection density; Stansted and Luton often win headline short-haul fares; Gatwick sits between leisure long-haul and low-cost Europe; City suits short business hops when the fare gap is small.
Heathrow (LHR): deepest long-haul and alliance connecting inventory — often not the cheapest leisure one-way.
Gatwick (LGW): strong leisure long-haul and easyJet Europe; compare against STN/LTN on the same dates.
Stansted (STN) / Luton (LTN): low-cost Europe magnets — factor Stansted Express, Thameslink or coach into all-in cost.
London City (LCY): premium short-haul convenience; rarely the cheapest cash fare.
Multi-airport method: Google Flights complete guide.
| Airport | Usually best for | Watch-out |
|---|---|---|
| LHR | Long-haul + alliances | Higher base fares; longer security peaks |
| LGW | Leisure long-haul / easyJet | Rail vs tube trade-off to central London |
| STN / LTN | Ultra-low-cost Europe | Bag + transfer can erase the win |
| LCY | Short business hops | Aircraft/route limits |
Which airlines compete on cheap flights from London?
London’s cheap-fare edge comes from overlapping BA/Iberia/Vueling Avios networks, Virgin Atlantic long-haul sales, and dense easyJet/Ryanair/Wizz short-haul competition from secondary airports — not from one “always cheapest” airline. Short-haul: easyJet (LGW/LTN/STN patterns), Ryanair (STN-heavy), Wizz — force them into the same date grid.
Short-haul: easyJet (LGW/LTN/STN patterns), Ryanair (STN-heavy), Wizz — force them into the same date grid.
Long-haul cash: BA, Virgin Atlantic, plus Gulf and US majors — compare via metasearch then airline-direct when disruption risk matters.

When are flights from London usually cheaper?
London outbound leisure peaks school holidays (late July–August, Christmas/New Year, Easter) and half-terms; shoulder wins are typically late January–March and mid-September–early November excluding half-term weeks. Long-haul to Australia and Caribbean still follows destination seasons more than London weather.
Set alerts for a whole month window rather than a single Friday–Sunday city break — see how holiday deal alerts work.
Ski and summer Med routes inflate early; book those earlier than generic Europe city breaks.
No invented fare amounts on this page — read the live month grid for the week you can actually travel.
When is a nearby airport or positioning flight worth it from London?
A train or short hop to Manchester (MAN), Birmingham (BHX) or Bristol (BRS) is worth it when the fare gap clearly exceeds rail/coach plus the value of your time — common on ultra-low-cost Europe, rarer on long-haul where LHR/LGW inventory is deeper.
Run LON vs MAN/BHX on the same outbound week before you commit.
True positioning flights (fly cheaply to another hub, then onward) need buffer — positioning flights guide and separate-ticket risk.
Eurostar sometimes beats flying to Paris/Brussels once you price centre-to-centre — compare before defaulting to STN.
- Price LON multi-airport + one regional UK airport
- Add Express/coach and bag fees before celebrating STN/LTN
- Only position via MAN/AMS/DUB with a protected buffer
- Compare Eurostar for near-Europe city pairs

When does cash beat points for London departures?
Cash usually wins for simple short-haul Europe with flexible dates, basic-economy-tolerant packing, and when Avios surcharges or award space make points worse than a sale fare. Points win more often on peak long-haul when a companion voucher or sweet-spot award undercuts the cash cabin you actually want.
