I BARELY made the flight due to insanely long screening by TSA. They literally looked at every single item in my carry on bag. This was particularly ridiculous given my early check in at the counter and entry to security screening, the fact that few people were traveling (day after Thanksgiving). DSM is the worst airport I've been at in the world (!) for efficiency of security screening and TSA. There were something like 8 TSA agents working and very few passengers passing through security. I could have easily missed the flight - was one of the very last to board. Can't an airline like AA follow up on something like this?
