Hi
You can have 2 other people (or your family with all kids under 24) on your staff travel and then get :-
- Unlimited ID90's (either economy or Club priority)
-1 free J ticket when you join (per year)
-a second free ticket after 5 years (on a F priority)
Also get 30 Hotlines per year (to use for friends / family)
ID90's are not cheap anymore though (eg £220 to singapore, sounds cheap but it a busy route)
