I have a colleague who is currently doing this every day via Oyster PAYG. I advised that a Season from Sidcup to London Terminals would save a bit of money (about £3 per day) but I also noticed that the Season from Sidcup to West Hampstead Thameslink is even cheaper.
Is the latter ticket valid via LBG (assuming a walk to Blackfriars) or is it limited to a particular route? Or is there an even cheaper way of doing this which I've missed?
