if you are checking in here to see the latest on flights, just to let you know, we haven't booked ours yet. We got a great deal last year at the end of Feb and are hanging out to check.
We are using Delta e-savers, US Airways, Aerlingus predominantly, as they have great deals usually as the time gets on. Please check on their respective pages, and also enter your dates into bing.com to see what you get.
If anyone has any questions or worries, just comment or send an email to firstname.lastname@example.org and I will happily answer or help you figure this out.
All the best!
