Interlaken to Zurich early morning

Hi,
I will be in interlaken for 4 nights.
I will have flight at 7:45 from Zurich airport to London.

My question:
> How much time before I need to reach airport.
> Will there be any train available early morning like 4 AM.
> Will there be any other mode available to commute.
> Or should I go to Zurich a day before and then catch something from there early morning.

Hi atanwar,

I assume you need to be at the airport 1 - 2 hours in advance or so, but you best get that info from your airline. Anyway, you need to be there pretty early so I would personally prefer to get an hotel nearby. Please check this list of hotels near the airport, some even offer free transfers to the airport. The timetable shows all the options to get from Interlaken to Zurich airport. There's only a train connection.
