This is the first report I have seen of a contact centre, albeit GGL, offering an LNER ticket, did they book you a new PNR and give you a link to a special print area? I know this is a LHR offering, but it would be useful to know if people going the other direction can use this.[/QUOTE]
Yes, this was a first for me too and somewhat surprising how easy the process was. The existing PNR was used and in fact the land sector appeared in MMB (somewhat hilariously) as “9B6732 Kings Cross to Newcastle International - this flight is operated by First Great Western” - no mention of LNER.
The GGL Supervisor liaised with LHR in order to make it happen. Although booked on a specific LNER service, it was valid on any train on the nominated date. No printing was required and the system generated a PDF ticket. Although my itinerary was in J, I was booked in Standard Class on the train but was just pleased to get home after another BA debacle.
