I was @ TIA today.
Its been a long time since I have been there. All the construction is done in the main terminal and it looks really nice. They have new centralized Departure and Arrival Information for all airlines in the main terminal now. Northwest has moved to Terminal A. They have new electronic signs above the entrance to the tram stations to the various airsides that are really nice. I wasnt in baggage claim though, can anyone tell me if construction is still going on there? I know they were going to update baggage claim.
