Rather than fly I opted for the scenic 8 hour bus ride . Booking through BusBud.com I was able to reserve one of the top front seats.

Bus service in Chile and Argentina is fantastic.

Unfortunately I fell asleep during some sections of the journey.

From Mendoza I did the second half two more times as my local bus to Aconcagua took the same highway. Well worth doing if you get the chance.
