Bargain travel to LHR: the N9 night bus
I arrived at T5 this morning on the N9 night bus from central London. It cost me £1 on my Oyster Card. The journey time from Aldwych is about 1 hr 15 mins, and from Kensington High Street 1 hour. The buses run roughly every 20 minutes through the night. Worth considering by anyone who is feeling the effects of the credit crunch and has an early flight from LHR. (I realise that it won't necessarily appeal to everyone!)
