Quick answer
London is one of the nine destinations Gigi Becker curates personally. The default board-meeting city. Book the Concorde Room, not economy. Sample routing: LAX → LHR nonstop, overnight (about 10.5 hours) · Business.
Best for
Investor meetings in the City, dinner in Marylebone.
When to go
May–Sep for weather that cooperates; Dec for the lights.
