This week's Net special e-mail has BOS-LHR for $269, which is pretty good in my book. You can usually get 10,000+ miles out of that city pair with creative routing, making it easily worth a mileage run (if you bring your own food and sleep on park benches; otherwise 2+ days in London can do a number on your budget).
The same e-mail also has RDU-LGW for $359, not as outstanding but still a decent fare.
Usual rules: ticket by this Friday (3/28), depart April 2-4, return April 7-9.
(edited to correct $10 typo in RDU-LGW fare)
