Have flown out of Midway numerous times this year and also Ohare in May. After that fiasco in May, they did some serious looking at the problem. Now, we flew out between Christmas and New Years from Midway when a few days before the flights were shut down, so the crowd was full since flights had resumed and we may have waited 30 min (no tsa pre that time) Southwest Airlines was giving random tsa pre boarding passes at one time. I really have no explanation for the midway lines in May...
but less than one week later from the long lines at Midway and O'hare, I was flying on United from O'hare and got to the airport rediculously early (4 hrs) for an international flight, only to find I got a random tsa pre stamped on my boarding pass... 5 min later ...So Hello airport bar! And the wait but it was with a cold drink and getting to know other travelers.
I believe that TSA is pushing people to get this Global or TSA pre for the income. Let them. I don't mind chatting with the people in line to go thru security.
Coming up will be our 5th trip to Europe in 2 yrs. No Global or TSA Pre... We've lived in Asia before and during 9/11 and waiting in the queue is just part of the travel experience, as long as it isn't over 30 min. haha.
Happy Travels.
