Thank you both. It's good to know I can hop on Zurich tram 13 when it begins operating in the morning (around 5:30AM) and manage to not feel like I am rushing if I arrive at the airport at 6AM for my 7AM flight.

I'm really more concerned now about getting my upgrade to LH F confirmed in ZRH if at all possible, so I can head to the FCT in FRA when I arrive. - but I've got another thread over in the LH forum dedicated to that mess. I've used the FCT before es-FRA and I'm spoiled rotten
