The departures board at the Qantas terminal at 6am is funny. There's a flight to Sydney – a fully loaded 737-800 – every 15 minutes. Over in Jetstar it's the same, Virgin the same.
Notice that SFO to Newark makes the list further down. If you summed all Bay Area airports to all New York serving airports. Across all airlines... You might see a closer contest.
Also the fact is that the Business lounge at CBR is practically an extension of the office from 5-7pm. Everyone you know is there.
Do any other airlines have an equivalent to CL? I assume the greater availability of private jets in the US rules it out there.
They've got just enough of an edge, plus the whole tie-in to the global Oneworld program. Our company's Chairman is a member of the CL, but AFAIK if I requested a Virgin flight that wouldn't be an issue.
