The UK has a few sleeper trains, where you get a proper (if small) cabin with a proper bed etc. They run from London to some of the major cities; I'm particularly fond of the London-to-Inverness sleeper (the buffet car does a killer haggis). Cost wise, it's considerably more expensive than an Easyjet cattle-car class flight. But the big benefit is that it takes no working-day wall clock time. I can leave the office in London after work, comfortably reach Euston where I board the train and settle down in the buffer car with a drink and wifi; then I arrive at Inverness at about 0700 the next morning, refreshed having slept well. All the travel happens while I'm asleep. Conversely, flying Easyjet takes waking time. I have to leave the office in the middle of the day, get to the airport, wait, check in, wait, board, fly, and arrive at my destination still during waking hours --- it eats most of an entire day. I can't tell how this bus would compare against an overnight red-eye flight, because we don't have those (the UK's not big enough!). But I imagine that having a bunk would mean that I could actually sleep on one of these buses, unlike the fake sleep you get on planes. I'd definitely consider this, even if it was more expensive than the plane.
