I know there are many answers to these questions somewhere in the helpline, but with the search function not working......
Is the best/quickest way to get from Heathrow to Kings Cross via the Underground (Picadilly Line) or Heathrow Express then taxi to Kings Cross? Since we are using miles we have two connections before getting to London, so we will be rather jet lagged/tired once we arrive in London. We'll each have a roller bag carry-on with our day packs.
Next questions are regarding train tickets. Our flight is scheduled to arrive at 10:30am at Heathrow, so we plan to take a train to Edinburgh same day.
1) How much time should we plan on from the time we get off the plane, through immigration, then to Kings Cross?(no checked luggage)
2) The advance tickets are definitely the least expensive (21 pp), but it appears that if our flight is delayed, or we miss a connection, we are out of luck if we do not make the train for which we would have tickets. Please confirm.
3) But need some clarification on Super Off Peak fares. So about 3 months out Super off peak fares are 67.50 pp. It sounds like if we arrived earlier or later than planned, as long as we traveled same day, we could exchange our tickets for a different train. Does this apply even if the train with tickets already departed? Are are the Super off peak fares available same day of travel at the same price as 3 months out, so we could just buy tickets when we get to Kings Cross?
4) If we purchase tickets in advance, it sounds like we'd have to get the tickets at the station from a kiosk using the credit card they were purchased with. Will magnetic strip credit cards work, or will we need to obtain reserved tickets from a ticket window?
