- Bargin berths aside, the problem with Serco's pricing isn't the prices per se - although they did dramatically increase from Scotrail - but the per-cabin pricing, so that for a person travelling alone the price is effectively doubled. For two people travelling together there is much less difference. Last time I tried to use the sleeper, while I was living in Aberdeen, a return to London booked five months ahead was over £400. Obviously I didn't take it.
Sharing with strangers is never coming back. It's far too problematic for women sadly, so per cabin pricing for Sleeping Cars is here to stay.
I can only surmise you were either booking ahead in a holiday period Friday or Sunday. The late booked last berth available sleepers I've been on have been ~£200 one way, but needs must.
IMHO this sleeper service will be safe for the forseeable future, because it's a favoured method for Scottish MPs to travel to/from their constituencies. But they do it on expenses, so they don't care about the prices.
My MP likes to fly. A lot. At £500 a month according to his expenses. Yes, there's also a Caledonian Sleeper claim for near 2K, which I presume is a Flexipass.
His neighbouring same party MP has
a total for £8 for rail expenses, but nearly 5K for air. I think the days of it being an MP favourite are in the past, not the present.
(Actually, it's wronly coded as a Railcard but he's got a £1650 claim for CS too.)
