Let me see here...
SAT - nope
ATL - yup, it's huge, but I didn't think it was that bad?
SMF - only been there once, didn't seem half bad, some funny art
STL - been there a few times, nothing special
CLE - nope (but will this spring)
SAN - when I was 7
MDW - been through here too many times on Southwest transfers... nowhere to eat here

BWI - I like BWI, really good food choices, and direct flights practically everywhere?
DCA - so glad that Southwest goes here... cramped as hell, but really convenient location
FLL - nope
LAS - hilarious to see the slot machines off the plane, that's worth some points right there
HOU - nope
BOS - nope
JFK - nope
DEN - some really good food, been transferred through here a few times and didn't mind it
PHL - nope
DFW - only bounced through here quickly
LAX - actually, this is one of my least favorite airports, but the approach vector has a fun view
MIA - nope
LGA - been here, didn't spent enough time to really think too badly about it
IAD - I don't know why you would hate on this place--it's meant as an international hub
ORD - been through a few times, superior to MDW, at least
IAH - nope
SFO - not much there but the gates, but easy enough to get downtown from there
EWR - never been
15/25 for me, some of the rankings up there I have to disagree with (BWI in particular).
What did they rank highly that we are missing? DTW? Nashville? Love Field? Charlotte? Pittsburgh? Cincinnati? MCI? The smaller LA airports? AUS? Sky Harbor? Albuquerque Sunport? Minneapolis? PDX? I can't think of many more big ones that serve as anything like a hub for any of the major airlines.
