I had kiosk issues this afternoon at JFK and was pretty aggravated to have to stand in the huge line to "please see a service agent." I think the kiosk got confused because I tried to check in at home, but couldn't print the boarding pass and figured I'd just print it at a kiosk like I do for other airlines. I did not bank on having to stand in a line for 30 minutes because the kiosk decided to not find my reservation. I noticed that the line was long only because there seem to be A LOT of passengers who don't know how to use the self-service kiosks to check in for a boarding pass and then get in the shorter & faster line to hand in your checked luggage. They just get in the line for the service agent and have the agent do everything for them, tying up the passengers who actually need to see the agents. Well it feels better to vent.
