Heathrow connects to more London neighbourhoods without changing trains.
05
On a ~5-hour journey, the transfer time difference is proportionally significant.
When Gatwick is actually the better choice
Budget airline ticket savings of €70+ can justify the longer Gatwick transfer.
If travelling with only hand luggage — the baggage cost gap disappears.
Gatwick is better for south London, Gatwick Airport hotels and Brighton connections.
easyJet and Vueling offer frequent MAD–LGW flights at very competitive prices.

Common mistakes on this route
Choosing by ticket price only
Add baggage fees, airport transfer cost and schedule waiting time. A €50 saving on the ticket can disappear after one checked bag and a coach transfer.
Ignoring the airport transfer
Gatwick is 45km from central London. The transfer costs time and money — factor it in.
Forgetting baggage costs
Budget airlines into Gatwick often charge €35–60 for a checked bag. Full-service airlines into Heathrow frequently include it.
Not comparing Madrid airport access
Metro Line 8 — factor this into the total journey before comparing London airports.
Quick answers
Gatwick and other budget-airline airports often have cheaper advertised ticket prices from Madrid. However, once you add baggage fees (€35–60 on budget airlines) and the longer, more expensive airport transfer, Heathrow is frequently cheaper overall. Always compare the complete door-to-door cost.
Gatwick Express — ~30 min, ~£20 off-peak.
Elizabeth Line — ~35 min, ~£12 off-peak.
Yes. Late-night arrivals at Gatwick mean fewer transport options. Late-night arrivals at Heathrow still have the Piccadilly Line (24-hour on Fri/Sat) and night buses. Early morning departures may require arriving at the airport the night before.
The Piccadilly Line costs £5–6 and takes 50–60 minutes. The Elizabeth Line costs ~£12 and takes ~35 minutes. Both run frequently throughout the day. The Piccadilly Line is the budget option; the Elizabeth Line is faster and more comfortable.
