London Heathrow to Miami is a long leisure and business overnight where BA, Virgin Atlantic and American have typically flown non-stop — verify live. Lie-flat business is the main sleep upgrade; premium economy suits upright resters. MIA ground access is car-heavy compared with Heathrow rail. Not for travellers who need same-day flexibility without checking visa and connection rules.
