LAN just rescheduled my flight from Santiago to San Francisco connecting in Lima.

The connection time went from 110 minutes to 40 minutes (arriving at 23:55 departing at 00:35). I am traveling in Business so should be able to get off the plane quickly. Is this going to be enough time?

There is a flight departing SCL at 21:00 and arriving in LIM at 22:50 but LAN is not showing any availability for an award ticket on that flight. The award was booked with British Airlines miles. Do you think there is any chance of getting LAN to put me on that flight instead?

Thanks!
Mike
