Pulled the trigger on my July trip to US - £1,602 (including CC fee) for 920 TPs. DUB-LHR/LCY-JFK-LAS/SEA-JFK-LCY/LHR-DUB (AA flights on AA code of course, as learnt here). Now just need to come up with best way to fit in various places between arrival and departure (family in LAX, friends in NYC and SEA etc)
