LGW-AMS-LGW-JER//JER-LGW-AMS-LGW - 240TPs in Club Europe, spread over a two weeks booking LGW-AMS-JER return on AA's Multi City tool.
You need to book two one way tickets - JER-LGW and LGW-JER - these can be Euro Traveller to add a further 20 TPs to your balance, or POUed to CE for 80 TPs.
This trip takes two days in total, but is cheaper than a Club World return (around £600 excluding the two one way positioning flights (not needed if you stop over in JER)).
