I've just spotted this fare on ITA was able to get it priced up on AA.com. Not sure if this has been posted here yet.

It's an IL7SALE fare. Restricted to 12th to 27th April outbound. On sale until 4th Feb.

BRU-LHR/LCY-JFK-LAX-HNL | I/I/I/A | £1,397 return | americanairlines.co.uk | 1200 TPs | £1.16/TP

The evidence (plenty of variations were available, there are probably better timings etc). If anyone can push this onto an A transcont leg that would be astonishing.
