agree...I always think companion tickets are quite a good choice, esp when used with e.g. some segments of RTW tickets which are somewhat less expensive already. e.g. on some US/Europe trips I have, I often start in TPE/BKK, buy a RTW ticket (which is cheaper than roundtrip J/F anyway), and include HKG-xxx-HKG segments in the end as a "free sidetrip". and use this in the future as my leisure trip, by redeeming companion ticket on this side roundtrip for my wife to go with me.
