Summer is the most expensive time to travel to Europe so finding cheap airfare is nearly impossible. While I've been able to fly from Chicago to the London for under $500 in the winter, I am lucky to find anything under $800-900 in the summer which really is frustrating because of course I want to be there when the weather is nice (although we all know the weather is rarely nice in England) and somewhat warm. I've searched tons of websites for the last 3 months looking for something decent and I found something just the other day so I thought I'd share. I'm sure this site has great deals available anywhere, not just from the US to the UK.
