Makes no difference to you Kendrick, it only affects the ex BMI captains and all of them are senior to you wherever they end up anyway. This thread is historically known for thread drift (guilty in that respect myself) so don’t worry too much about it.
Personally I think JSS will be better for Short Haul (virtually no one wants a mixture of daytips and tours which is all 90% of the Triplines are, although it remains to be seen how effectively you can build a roster consisting of either day trips or tours and a lot will depend on seniority/knowing the correct JSS tweaks). I suspect for Long Haul it will be a !!!!show compared to Bidline, but who knows?
