I had bought a ticket for 2:12( Golders Green am as my flight was at 6 from Stansted. 3 fricking busses didn't actually show up, imagine the amount of people in the station. It did arrived one after 3:30 and obviously almost full leaving plenty of 2:12 tickets on ground as the priority is the actual hour. At return, in stratford got in the station, the assistant said it's arriving in 15 minutes. Half an hour later comes back to say arrives in 10 minutes. 45 minutes later and still no buss. Won't recomand, absolutely not reliable. You will end-up paying 3 times more for a cab or re-book your flights.
