A couple of weeks ago I bought 2 Advance tickets to Kings Cross on 29th April and the e-ticket was the only option.
I was a bit wary of not having a "proper" ticket, but am more relaxed now having given it a try and finding the e-tickets are printable. I think this comes from having had my pocket unsuccessfully felt on holiday in Rome a few years ago, and the consequent fear of having my phone lifted along with much essential info etc.
Now that tickets for 1st May are available, this morning I bought an Advance for the LNER part of the return journey, and found that all the usual ticket options were there.
I wondered whether the "e-ticket only" option might be connected with easier cancellation of tickets should timetables be changed and many refunds need to be issued.
On a different aspect of buying tickets online.
Interesting to see that the allocated reservations for both the Avanti tickets from Euston to Glasgow and LNER from Stirling to Inverness both came up with 2 seats at the end of the coach alongside the luggage racks. These were soon edited.
Is it possible to select seats on the RailForums Ticket page? There are a couple of open Day tickets I need to get and will have a look there, but wanted to be selective for the longer legs of this trip.
