I'm flying Delta out of LGA Saturday morning, and am wondering if it is worth visiting this lounge, considering I'll be with two friends who don't have pre-Check. I've been hearing about the awful security lines across the country all week, but haven't flown out of LGA recently so I'm not sure how bad it is. How long would we have to leave to get from the lounge to terminal C, get through security, and get to our gate? Thanks
