Gee I keep reading how bad MIA is, my last trip though lines went really fast 10 minutes tops, not worth using the speed pass I paid for, maybe next time. But I will say they could use some better signs on how to get from one end to the other end.. Some one's advice here on how to find the elevator, was accurate. I was at the elevator right away, then I some air port genius employee thought I was lost and gave me direction to some where else

wasted 20 minutes back tracking to where I wa.
On the way back once out of immigration I was trying to find how to get to the Tri Rail for future reference, and was sent from one end of the airport to the other end 3 times by the "Official Help Booth" finally gave up on that and asked a Non airport cop who was working security for the Governor to stop in, he did not know, but asked his buddies and they showed me where to go ( not to hell, the bus stop) .
But In Jan 10 I try again, and we see,
We all have our bad airports, but how many of them were ever designed for the amount of traffic they are expected to carry these days. Most probably need to torn down and completely replaced,ex-ORD ( not practical)remember most are pre 9/11 so that adds a whole extra layer of stuff they were not designed for. Us old guys can still remember the days when any one could walk up to the gate. So they add and adjust and add some more,rebuild a little, change again with limited funds. Unless of course every one is willing to pay some taxes or fees to speed up the reconstructions and do it right , and that's not a very popular idea .
