Which London airports should you search for cheap flights?
Link to this answerSearch 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?
Link to this answerLondon’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?
Link to this answerLondon 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?
Link to this answerA 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?
Link to this answerCash 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.
