ATL is certainly a marvel of an airport, but I would have to agree it's not near as much fun in terms of the livery of international airlines... nothing like the SFOs, ORDs, DFWs and JFKs of the US (or AMS/LHR/CDG of EU) where one can see oh-so-many big and small ranging in colours from Air Canada Red to KLM Royal Dutch Blue. ATL just seems to be a whole lotta' Delta, with some other coloured specks. Though I am pleased AirTran is doing well!
To add to BA's point, a city need not be large to support massive aircraft movement. Minneapolis-Saint Paul is a classic example of this. The "Twin Cities" barely creep into the 3MIL mark for population (with 4MIL for the whole state total,) yet they were ranked in the top 10 for aircraft movement (even above DTW,) and in the top 20 in terms of passengers carried.
MSP is indeed small, but a very nice simple terminal with great shopping and restaurants. Construction on a 4th runway has began, and MSP's facelift should be completed in 2010; the new LRT (light-rail transit) connecting the airport to the Mall of America (with it's tax-free shopping) and downtown Minneapolis will open for riders in early 2004. (MSP has come a long way since its movie debut in AIRPORT, heh.)
Though Northwest does dominate here, much like Delta does Atlanta, we still get to see some nice international carriers like Air Canada, KLM Royal Dutch, and Icelandair... If only Aer Lingus or SAS would open a gate here!
Oh, and SAXman66... DFW is a way fun airport. Though AA dominates, and getting around that airport is difficult (my only complaint about DFW is that its tram system bites,) the FOUNDERS PARK they have there for viewing planes is almost in between the runways! It's amazing. Is it still open after 9/11? And do they still have the speaker playing ATC so you can listen as you watch? If only more airports had such a park...
Thanks for listening to my rant on my hometown in Minnesota...
