AgreeThat sometimes happens…just as often me and my Global Entry are long gone from the luggage carousel before the immigration line clears.
These days I rarely have trouble at the airport because I have the luxury of traveling during the week (not weekends). Not everyone has the opportunity, but if you can swing it, it takes a lot of stress out of air travel. That said, you still have to deal with the airlines prior to travel which I currently find more problematic. All IMHO, YMMV.
We avoid Saturday travel like the plague. Often flown on a Tuesday and it's been great.
