LH is supposedly going to stop crediting UA flights toward HON status effective April 1. That will make it very difficult for anyone to get HON unless they are flying in C or F on the LH (and integrated) airlines. You'd need to average over 130K miles per year in paid C on LH (and the other allowed airlines). And the upgrades for a UA 1K are much more generous than for HON (5 long haul segments allowed over two years).
You may wish to consider crediting some flights to LH to earn SEN status (and keep 1K), which you could get with 40-50K *A in paid C, D, or Z in a year, once every other year. You'd have to decide if the benefits are worth it to you.
Considering that UA is giving 2 more SWUs for each 50K *A status miles over 100K, you have an incentive to stick with UA I think, to earn those.
