谢谢你 另外想问一下，我20:35下机，想最少要大半个钟才到达underground，还有人在售卖oyster card吗?

You can use Oyster card from Heathrow Terminal 4 to Lewisham there is no need to buy ticket from railway station. It costs £4 for a single cash ticket £3.50 by Oyster card. You only need to pay £3 for a Oyster card deposit. You can return the card and have your deposit back when you finish. There is an underground station at Terminal 4 for further information please check journeyplanner.tfl.uk/user/XSLT_TRIP_REQUEST2?language=en&sessionID=JP08_331870505&requestID=1&tripSelector4=1&itdLPxx_view=detail&tripSelection=on&mand=nop Price details tfl.uk/tfl/tickets/faresandtickets/2007/farefinder/default?from=Heathrow+Terminal+4&to=lewisham&type=Adult&showfares=Show+fares Hope it helps参考: I live in London你系Heathrow T4落左机出到接机大堂你就睇返指示牌... 佢会写住Underground... 你落到去地铁站就去Ticket Office买张Oyster卡(佢个Ticket Office开到22:30)...
