Hi all! I will be traveling to London Heathrow from Chicago O'Hare on June 4th and returning June 10th. Has anyone recently been to either of these airports and can give me insight on the security and/or custom lines?
I've heard the news recently about the 2 hour lines in security and want to get an idea of when to arrive at each airport. I normally plan to arrive 2 1/2 hours before my flight, but now I'm thinking I should arrive almost 4 hours before. Any recent experience you can provide will be helpful!
