I haven't experienced nosecone on a 747, but have done the Concorde. My partner at the time (1996) worked for BA, and they were struggling to fill the seats for most trips. You probably know, but the BA service was 100 seats, and entirely first class.

The trip was LHR to JFK.

Pricing was ludicrous -- I think around AUD $600 (one way). This would have been 10% of list. The joys of ID90.

I have a handful of recollections. Most of the seats were empty. I could not stand fully upright in the aisle (I'm 188cm, or ~ 6'2"). Breakfast was delicious, and it was five courses. The whole flight was very noisy. At cruising altitude I was sure I was seeing curvature of the planet (I concede this may have been wishful thinking, or an artefact of the windows).

It was about four hours, and you really did land before you took off, on that particular leg.

At the time - young & holidaying - this wasn't as big a deal as it would have been in more recent years, when work obligations transformed travel from enchantingly wondrous, to onerous obligation.
