Hi, if you have an advance ticket marked ‘Lner & Connectns’ for a journey on Thameslink into London then LNER, can you catch an earlier train than your booked Thameslink (and then connect onto the correct booked LNER) or is this against the ticket terms please? And either way, if you have any evidence that you could link to please that’d be really helpful for me getting my head around it. Thank you
