The train: two thirty-minute services that are not the same train
Two rail services run from Brighton railway station to the airport station in the South Terminal, and both are quoted at half an hour. They are not the same train. Both are operated by the same parent company, Govia Thameslink Railway. The stopping patterns differ. The prices differ. The headline number does not — comparing them on time alone is comparing the wrong thing.
Same headline number, different train
30 min
Gatwick Express · non-stop
Runs non-stop in 30 minutes. It is a limited-stop service run by Govia Thameslink Railway, and the fare is usually the higher of the two.
33 min
Thameslink · average, 30 at fastest
Thameslink publishes 33 minutes on average and 30 minutes at its fastest, across 107 services a day. It calls at intermediate stations, so the fare is usually lower than the express and the frequency is higher.
Rail fares move with how far ahead you book. As of 3 August 2026, an advance single is seen at £10.30 and a walk-up single at £14.50. Split fares and promotional pricing occasionally reach as low as £4.00 but depend on availability. Check the current price on the operator's own site before you travel, because these figures move.
Against the advance rail single at £10.30 a head
Book far enough ahead and the train holds the advantage until the party reaches seven.
Against the walk-up rail single at £14.50 a head
Turn up and buy on the day and the balance moves much earlier — from four passengers onwards.
Two crossover points, marked
On the advance single our fare wins from seven passengers, and the margin at that point is only £0.86 — close enough that anyone choosing on price alone could reasonably go either way. On the walk-up single our fare wins from four passengers, with a margin of £1.09.

So the honest sentence is not "we beat the train". It is that one or two people travelling light and booking ahead should take the train. A family with cases, an early departure before the trains run, or anyone starting a mile from Brighton station with a suitcase is better off in a car. The station-to-airport-station journey is 30 minutes. The walk to the station, the change if any, the ticket queue and the platform time are all extra, and none of them appears in the headline number.
The airport station is in the South Terminal. If you are flying from the North Terminal, arriving by rail means the free inter-terminal shuttle with your luggage.
