I haven't been to Cleveland Hopkins Airport for a few years. How early should I arrive before my flight?
I'll be leaving on Sept 1st, which is around Labor Day weekend. Don't know if this will effect anything. It leaves in the afternoon, and I'm guessing I want to get there 2 hours before my flight leaves, but I wanted to hear from anyone who has been there lately. I'm flying through Delta. Also, if anyone knows of any websites that list what NOT to take on an airplane now, that would also be helpful. I wasn't sure where to place this question, either Cleveland or Air Travel, but figured Cleveland was more local. Fryemall Thanks for the link :o)

For Labor Day weekend only, arrive 2 hours early and you'll be fine. Otherwise, get these an hour early and you'll be fine. Here's the TSA forbidden list: http://www.tsa.gov/travelers/airtravel/assistant/editorial_1012.shtm
