last few years there have been decent ex-EU sales right about now.
2 years ago I got DUS-LHR-LAS-JFK-LCY-(LHR-DUS) - 600 TPs for £1200 (booked on AA.com). Last year the same routing was £1500 ex-BRU.
In this sale you can do BRU-LAS in J for £1280 which is very good. Haven't checked the TP run routing above, but I expect it will still work. The minimum 7 day rule, which hasn't applied in previous years, is rather annoying though - I usually do 5 nights.
