Not sure why anyone in SE1 bothers with the Gatwick Express when you can get a train direct to Gatwick (and Luton) from Blackfriars Station
. It takes around 35 mins, so not much difference time-wise. It's probably also cheaper, but I can't vouch for that - no doubt someone on here will know the answer to that. Also, anything which involves road transport when you have a flight to catch is decidedly risky, in my opinion, as you can never be certain how long the trip will take due to congestion, road closures, possible accidents etc.
