One's impression of this airport greatly depends on the location of the gate you arrive at vs. the gate you're going to depart on.
It can sometimes feel like you're never going to reach your gate no matter how long you walk.. Or to be more specific, I once had a 20 minute walk from my arrival gate to baggage claim.. and that was in business class.
I do enjoy the restaurants and other amenities..
The baggage arrives mostly on time depending on airline.
Pro tip: check out the Starbucks by the baggage carousels.. they brew some good beans.
Watch out for: its difficult to actually leave the baggage area,, there are a myriad of barriers and more exits than you can count on one hand.
Big minus one star for having off-site care rental.. No one wants to have to take a not insignificant bus ride after a 5 hour flight from the east coast.
Usually at this point you hate most modes of transportation anyway (US Airways I'm looking firmly in your direction)...and having to lug your luggage up and down more times than you would need to at other airports with on-site car rentals is just not going to create a positive experience with the traveler.
And finally, not enough power outlets for charging mobile devices!! In this day and age these should be ubiquitous! But instead, one sees tired looking business people sitting on the floor around a charging tower with the life draining out of their eyes. Actually this last bit made me change my rating from a 3 to a 2 when I thought about it.
