My husband and I ( USA senior citizens) are traveling Heathrow to Moreton-on-Marsh in September for a week stay in Chipping Campden and Blockley. Then back to London near to Kensington Gardens for a second week. Trying to determine if we would be best purchasing a pass for two traveling together or just individual tickets.
'A pass for two traveling together' - do you mean the Two Together Railcard? Or something else?
With what on the face of it is one return rail journey the answer to that would be no unless you are travelling at peak time and can't get an advance type ticket.
Moreton to London Paddington from £6
A pass would be overkill
You might not want to commit to an advance-discount ticket to match up with your Heathrow arrival, but could commit further ahead for your return to London. If booking both legs on shorter notice, roundtrip discounts can be significant.
Why would you recommend not purchasing an advance ticket from Heathrow? We were thinking of allowing two to three hours following arrival time.
A Railcard is not valid on Heathrow Express.
You can get it at Paddington, carrying those pictures you will need.
If you plan too tight a connection, your plane may be late (or rescheduled by the airline, not unheard of), you could have the bad luck to spend 90 minutes in the immigration queue, you might just miss a Heathrow Express and herefor have difficulty making your train at Paddington.
I don't believe that through fares are available from Heathrow which is not on the National network.
The trains from Heathrow are run by the airport.
