Matrix currently quoting EGP29k (about GBP1100) for CAI-LHR-JFK-LAX-HNL and back every day in September except Thursdays and Sat 30th... no idea why !
As previously noted, the journey itself is about £1.00 / TP so excellent value for BAEC however getting to CAI is a PITA and being in CAI is a PITA and leaving CAI is a PITA so I'm out ...
