If you are looking to go to Europe this summer, with the adding of weekly flights to LHR, now may be the time to find some good flights.
As you can see searching one way each way I find many days with 100k seats. Now it is you turn to do the work to find seats from where you are to ATL and from LHR to where ever you want to go in Europe!

Enjoy! – Rene
