I've used it in ATL going to PHX, at JFK headed to SVO, and loved it. It allowed me to the front of a line at JFK with a Russia typical 100+ pushing people in it.

However, for the first time yesterday, I felt the ire of my fellow passengers. I and my wife along with our 4 kids (great travelers btw) walk out of the CRC at DFW and stroll to E15 where about 30 people are in line. We Breezeway it up to the front where the GA stopped processing the other passengers and hopped over to us instead. The ire came because dummy me failed to get a gate check tag for the stroller and car seat before going to the front of the line. That was not right and I apologized once I remembered my fub-up. Still though it probably took 90-120 seconds to process the 6 of us. Shame on me.

Other than that I've never felt the glares of other passengers though I am sure they are there. I tend to look straight ahead and get in my big blue seat as soon as I can.

So far, I LOVE the Breezeway concept!
