i work at london city airport, and commute there every day from crystal palace road! my main way of getting there is overhead (from ED or peckham rye) to london bridge; jubilee line from london bridge to canning town; then DLR from c-town (as an ex-east londoner, i'm allowed to call it that) to LCY. though mad, manic shift work means five thirty in the morning starts sometimes! when i'm on those, i'll hop on the first 40 to aldgate, then n15/n50/115 to canning town, then 474 to the airport. a nice little variety for all you travellers, there! how many of you use British Airways from LCY?
