I've never used the seat selector so can't comment on that, but the prices matrix looks the same as it does now doesn't it?
No. The previous version presented Standard and First Class tickets in the same single-view matrix; they're now tabbed and have to be toggled-between.
I've been using the LNER site for a long time (plus its predecessors, ever since they put in the "MixingDeck" interface), whatever they have done recently which introduced this booking engine update has finally driven me away.
Neither my wife nor I could find the option to "add" additional tickets to the basket any more, and the information density is just terrible for a computer (you used to be able to see the whole carriage at a time on the seat selector, not any more), plus you used to be able to get a good overview of all the pricing.
I do wonder if this was yet another way of "trying to make split tickets difficult to buy", I wouldn't put it past them.
LNER's webmasters have also clearly been going super zealous on blocking any nonstandard browser, I just get blocked outright when using Chromium on a Raspberry Pi (in incognito mode).
The forum's own new booking engine is now clearly superior in many ways and this was the final tipping point for me to take the plunge. I'll miss the automatic delay repay, but hey ho.
It appears possible to still 'force' the site back to the old interface, which may be of particular interest/use to those wishing to avail of AmEx (et al) cashback.
The process is to put a random search in, select a random non Advance ticket (to avoid locking out any limited availability for the journey you actually wish to make) and go through the log in to your account stage and as far as the Delivery Information page at new.lner.co.uk/buy-tickets/delivery-information/.
At this point, go into the address bar and delete 'new.' and press enter.
The site will then revert to lner.co.uk/buy-tickets/booking-engine/ and the previously-selected ticket will disappear into the ether of an unclaimed basket.
You should then be able to buy tickets through the old process, including the functionality to add multiple tickets to the same basket and use the panoramic seat selector for LNER-operated services.
And that's why they stopped selling them a while ago, they don't want to.
As I understand it, the implementation of the functionality was blocked from the website at the last minute, as the DfT wasn't a fan.
It was released to the App. only, quietly.
Then it disappeared from the App., too.
