Yep, it must be Keflavik - Reykjavik is too small and I think 737's are the biggest thing that go in there.
I work for Air Atlanta Icelandic and have been to Keflavic a few times - A bit too cold & windy for me!
I can totally agree with Taildragger's comments though.
AFAIK we don't have any ex- QF 747's with us, our latest aquisitions are from BA and a few other people. We have three 747-236's from BA that are fitted with Honeywell FMS's and are used as freighters.
