Is there such a thing? I ask because I am about to go on a two-week research trip, and will be flying out of Heathrow. I'd rather not get tied down to one particular route, so is there a ticket that will allow me to travel out and back from any station in Zone 6. In practice, this means going to Hayes and getting an extension on Heathrow Connect one way, and taking the Piccadilly Line the other way (I'm yet to decide which way round).
On the other hand, would two singles be cheaper?
