I was once fortunate enough to be seated on G-BOAG from Heathrow to Barbados (& back).
Heathrow was in cold, grey & dismal November. Barbados was 5(?) time-zones away, and tropical: and all I'd done was have an excellent lunch. Maybe with more wine.
The overwhelming feeling on arrival (because it was only then that exactly how far we'd travelled finally sank in) was, why aren't there hundreds of these things around: why do we bother with anything else? (though I think the normal airfare may have had something to do with it)
