A new initiative from Singapore Airlines and First Great Western allows through ticketing (on SQ issued tickets) from various railway stations in the West.
Here's the press release from the
FGW website:
First Great Western and Singapore Airlines are proud to announce the launch of through-ticketing from selected towns and cities in the South West and those served by Singapore Airlines' route network from London Heathrow Airport, including the Heathrow Express rail link between Paddington Station and the airport. Travellers will therefore be able to purchase a ticket for hundreds of different route options such as Cardiff to Singapore, or Sydney to Plymouth, etc.
The stations on our network which will be open to these arrangements are as follows:
Bath Spa
Bristol Parkway
Bristol Temple Meads
Cardiff Central
Exeter St. David's
Oxford
Par
Penzance
Plymouth
St. Austell
Swansea
Bookings open on 24JAN14 at
this website.
It looks like it's being powered by
Accesrail, which operates as a virtual airline with the code 9B. Each train is allocated a 9B 'flight number', and many UK railway stations are already allocated IATA airport codes.
